Full Text Available Background: There exists a need for context-relevant research aimed at facilitating the efficacious provision of early hearing detection and intervention services in South Africa. Objectives: This study aimed to determine the hearing screening procedures and protocols as well as referral protocols in use at maternal child woman’s health (MCWH immunisation clinics in South Africa. Method: Thirty primary health care immunisation clinic managers or acting managers were interviewed in two South African sample groups. An exploratory, non-experimental,qualitative research design was employed incorporating both quantitative and qualitative information. An interview using a questionnaire was administered with all participants. The questionnaire encompassed areas such as work contexts, hearing screening contexts and information management systems, as well as quality control measures in place at these clinics.Content analysis was then used to code emergent themes into specific categories. Frequency calculations of these themes were calculated and results described qualitatively. Results: No primary health care (PHC clinics placed within the identified sites provided formalised new-born/infant hearing screening and none of these facilities had equipment to do so. Most sites attributed the lack of formalised hearing screening to budgetary and human resource issues, staff training in particular. Non-formalised hearing screening protocols in place demonstrated inconsistencies in application across districts and none complied with Health Professions Council of South Africa (HPCSA clinic guidelines or any international guidelines. Conclusion: Results from the current study have assisted in identifying procedural and logistical assets and barriers to implementation of HPCSA clinic guidelines for early hearing detection and intervention (EHDI at immunisation clinics in South Africa.

Predicting social functioning in children with a cochlear implant and in normal-hearing children: the role of emotion regulation.

Science.gov (United States)

Wiefferink, Carin H; Rieffe, Carolien; Ketelaar, Lizet; Frijns, Johan H M

2012-06-01

The purpose of the present study was to compare children with a cochlear implant and normal hearing children on aspects of emotion regulation (emotion expression and coping strategies) and social functioning (social competence and externalizing behaviors) and the relation between emotion regulation and social functioning. Participants were 69 children with cochlear implants (CI children) and 67 normal hearing children (NH children) aged 1.5-5 years. Parents answered questionnaires about their children's language skills, social functioning, and emotion regulation. Children also completed simple tasks to measure their emotion regulation abilities. Cochlear implant children had fewer adequate emotion regulation strategies and were less socially competent than normal hearing children. The parents of cochlear implant children did not report fewer externalizing behaviors than those of normal hearing children. While social competence in normal hearing children was strongly related to emotion regulation, cochlear implant children regulated their emotions in ways that were unrelated with social competence. On the other hand, emotion regulation explained externalizing behaviors better in cochlear implant children than in normal hearing children. While better language skills were related to higher social competence in both groups, they were related to fewer externalizing behaviors only in cochlear implant children. Our results indicate that cochlear implant children have less adequate emotion-regulation strategies and less social competence than normal hearing children. Since they received their implants relatively recently, they might eventually catch up with their hearing peers. Longitudinal studies should further explore the development of emotion regulation and social functioning in cochlear implant children. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Hearing regulates Drosophila aggression.

Aggression is a universal social behavior important for the acquisition of food, mates, territory, and social status. Aggression in Drosophila is context-dependent and can thus be expected to involve inputs from multiple sensory modalities. Here, we use mechanical disruption and genetic approaches in Drosophila melanogaster to identify hearing as an important sensory modality in the context of intermale aggressive behavior. We demonstrate that neuronal silencing and targeted knockdown of hearing genes in the fly's auditory organ elicit abnormal aggression. Further, we show that exposure to courtship or aggression song has opposite effects on aggression. Our data define the importance of hearing in the control of Drosophila intermale aggression and open perspectives to decipher how hearing and other sensory modalities are integrated at the neural circuit level.

SELF-REGULATION STRATEGIES OF ORAL COMMUNICATION IN CHILDREN WITH HEARING IMPAIRMENT

Directory of Open Access Journals (Sweden)

Alois GHERGUT

2011-09-01

Full Text Available The study identifies some self-regulation strategies used by deaf children in order to make their speech more intelligible. To achieve self-control while speaking, the child with severe hearing loss needs not only a high level of intelligence, but also an effective lip-reading capability and a strong intrinsic motivation. This is the reason why there are many cases of children with a high level of intelligence, but with a mediocre lip-reading capability and others with a lower level of intelligence, but with a good lip-reading capability. These differences also depend on the degree of hearing loss. Among the self-regulation strategies used by the children that achieve an intelligible speech are: the cognitive and meta-cognitive strategies, the motivational strategies etc. These results are important while designing the therapeutic activities, and especially the speech intelligibility factor being crucial in the social integration of those children with hearing impairment.

Main hearing according to the new Serbian Criminal Procedure Code: Survey in practice

Directory of Open Access Journals (Sweden)

Soković Snežana

2017-01-01

Full Text Available The main hearing is the central part of the criminal procedure. In Serbia, the reform of the national criminal procedure legislation has brought about numerous changes related to this stage of criminal proceedings. Numerous objections have been addressed to the almost entirely new legal text. In an attempt to examine the advantages and disadvantages of the new legislation and observe how the prescribed rules are applied in practice, the authors have conducted an empirical research by attending 205 main hearings which were conducted under the rules of the new Criminal Procedure Code. The research covers a huge number of related issues but, given the page limit, this paper will focus on individual issues observed in trial proceedings. The focal point of reference is the examination of witness, but the authors also consider a number of other issues: the examination of expert witness, the delay of the trial, and the use of a video-link as a novelty introduced owing to the technological achievements of the modern era. The article is organized into several parts. The authors first provide a theoretical background of the issue under consideration and, then, present and discuss the research results provided in tables. In the third part of the article, the authors draw specific conclusions about the current practice in trials proceedings.

Hearing loss associated with repeated MRI acquisition procedure-related acoustic noise exposure: an occupational cohort study.

Science.gov (United States)

Bongers, Suzan; Slottje, Pauline; Kromhout, Hans

2017-11-01

To study the effects of repeated exposure to MRI-related acoustic noise during image acquisition procedures (scans) on hearing. A retrospective occupational cohort study was performed among workers of an MRI manufacturing facility (n=474). Longitudinal audiometry data from the facility's medical surveillance scheme collected from 1973 to 2010 were analysed by studying the association of cumulative exposure to MRI-related acoustic noise from voluntary (multiple) MRI scans and the hearing threshold of the volunteer. Repeated acoustic noise exposure during volunteer MRI scans was found to be associated with a small exposure-dependent increased rate change of hearing threshold level (dB/year), but the association was only found related to the number of voluntary MRI scans and not to modelled cumulative noise exposure (dB*hour) based on MRI-system type. The increased rate change of hearing threshold level was found to be statistically significant for the frequencies 500, 1000, 2000, 3000 and 4000 Hz in the right ear. From our longitudinal cohort study, it appeared that exposure to noise from voluntarily MRI scans may have resulted in a slight amount of hearing loss. Mandatory use of hearing protection might have prevented more severe hearing loss. Lack of consistency in findings between the left and right ears and between the two exposure measures prohibits definitive conclusions. Further research that addresses the study's methodological limitations is warranted to corroborate our findings. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Regulation and construction of nuclear powerplants: South Texas Nuclear Project. Hearing before the Subcommittee on Oversight and Investigations of the Committee on Interstate and Foreign Commerce, House of Representatives, Ninety-sixth Congress, Second Session

International Nuclear Information System (INIS)

Anon.

1981-01-01

On September 23, 1980, the Subcommittee of Oversight and Investigation held a congressional hearing to discuss the regulation and construction of the South Texas Nuclear Power Plant project. Discussion included recommendations to prevent problems, like the problem encountered at Three Mile Island, from occurring during construction and operation. The chairman of the Nuclear Regulatory Commission discussed the procedure for inspection and regulation process. One power plant at the South Texas project experienced significant problems because of an inadequate quality assurance and quality control program. These difficulties caused delay in construction, increased cost, and raised questions of safety. The problems encountered at Three Mile Island and at the first plant of the South Texas project provided the reasons for this congressional hearing

The seminar was intended to examine current practices regarding the conduct of public hearings and how these practices related to the statutory intent, to assess whether existing procedures are being followed, and to explore whether administrative or legal changes are warranted. The seminar format allowed exchanges of views among participants in the hearing process and was attended by members of the public, the General Accounting Office, Congressional staffs, NRC, and the nuclear industry. The report contains panel reports on scheduling of public hearings, procedures for Board notification, selection and training of panel members, hearing procedures, and Board functions

The results of the hearings concerning Wyhl and Biblis C show that the basic tendencies can also be found in the analysis of the formal licensing procedure within the ATVfV - Atomrechtliche Verfahrensordnung (an order of the Atomic Energy Law concerning the licensing procedure). The corresponding explanations are formulated in an understandable manner; thus disputes about function and procedure of the hearing are theoretically not to be expected. In practice, however, it is obvious that disputes about the usefulness and purpose of the procedure itself continue to remain the topic of violent controversies during the hearing. (DG) [de

Noise exposure and hearing loss prevention programmes after 20 years of regulations in the United States.

Science.gov (United States)

Daniell, W E; Swan, S S; McDaniel, M M; Camp, J E; Cohen, M A; Stebbins, J G

2006-05-01

To evaluate noise exposures and hearing loss prevention efforts in industries with relatively high rates of workers' compensation claims for hearing loss. Washington State workers' compensation records were used to identify up to 10 companies in each of eight industries. Each company (n = 76) was evaluated by a management interview, employee personal noise dosimetry (n = 983), and employee interviews (n = 1557). Full-shift average exposures were > or =85 dBA for 50% of monitored employees, using Occupational Safety and Health Administration (OSHA) parameters with a 5 dB exchange rate (L(ave)), but 74% were > or =85 dBA using a 3 dB exchange rate (L(eq)). Only 14% had L(ave) > or =90 dBA, but 42% had L(eq) > or =90 dBA. Most companies conducted noise measurements, but most kept no records, and consideration of noise controls was low in all industries. Hearing loss prevention programmes were commonly incomplete. Management interview scores (higher score = more complete programme) showed significant associations with percentage of employees having L(ave) > or =85 dBA and presence of a union (multiple linear regression; R2 = 0.24). Overall, 62% of interviewed employees reported always using hearing protection when exposed. Protector use showed significant associations with percentage of employees specifically required to use protection, management score, and average employee time spent > or =95 dBA (R2 = 0.65). The findings raise serious concerns about the adequacy of prevention, regulation, and enforcement strategies in the United States. The percentage of workers with excessive exposure was 1.5-3 times higher using a 3 dB exchange rate instead of the OSHA specified 5 dB exchange rate. Most companies gave limited or no attention to noise controls and relied primarily on hearing protection to prevent hearing loss; yet 38% of employees did not use protectors routinely. Protector use was highest when hearing loss prevention programmes were most complete, indicating that

Stearn, Natalie; Swanepoel, De Wet

2006-11-13

Isolated reports of hearing loss presenting as markings on the iris exist, but to date the effectiveness of iridology to identify hearing loss has not been investigated. This study therefore aimed to determine the efficacy of iridological analysis in the identification of moderate to profound sensorineural hearing loss in adolescents. A controlled trial was conducted with an iridologist, blind to the actual hearing status of participants, analyzing the irises of participants with and without hearing loss. Fifty hearing impaired and fifty normal hearing subjects, between the ages of 15 and 19 years, controlled for gender, participated in the study. An experienced iridologist analyzed the randomised set of participants' irises. A 70% correct identification of hearing status was obtained by iridological analyses with a false negative rate of 41% compared to a 19% false positive rate. The respective sensitivity and specificity rates therefore came to 59% and 81%. Iridological analysis of hearing status indicated a statistically significant relationship to actual hearing status (P iridology were not comparable to those of traditional audiological screening procedures.

2014-07-01

To evaluate the possible effects of extracorporeal shock wave lithotripsy (ESWL) on the hearing status of the patients in this prospective controlled study. A total of 40 patients with normal hearing function were included to the study. We had 20 patients each in the study group and control group. The treatment parameters were standardized in all 3 sessions in which a total of 3000 shock waves with a rate of 90/min along with a total energy value of 126 J at the fourth energy level have been applied (Dornier Compact Sigma, Medtech, Germany). In addition to the testing of hearing functions and possible cochlear impairment by Transient Evoked Otoacoustic Emissions test at 1.0, 1.4, 2.0, 2.8, and 4.0 kHz frequencies, complications such as ear pain, tinnitus, and hearing loss have been well evaluated in each patient before the procedure and 2 hours and 1 month after the completion of the third session of ESWL in the study group. The same evaluation procedures were performed before the study and after 7-weeks in the control group. Regarding Transient Evoked Otoacoustic Emissions data obtained in study group and control group patients, there was no significant alteration in values obtained after ESWL when compared with the values before the procedure. A well-planned ESWL procedure is a safe and effective treatment in urinary stones and causes no detectable harmful effect on the hearing function of treated patients. Copyright © 2014 Elsevier Inc.

Age-related hearing loss in sea lions and their scientists

Science.gov (United States)

Schusterman, Ronald J.; Southall, Brandon; Kastak, David; Reichmuth Kastak, Colleen

2002-05-01

Interest in the hearing capabilities of California sea lions (Zalophus californianus) was first stimulated by the echolocation hypothesis and more recently by rising concern about coastal noise pollution. During a series of audiometric tests, we measured the absolute hearing sensitivity of two sea lions and two of their human investigators. Aerial hearing curves for each subject were obtained with a go/no-go procedure and standard psychophysics. Additionally, underwater hearing curves were obtained for the sea lions using the same procedures. Underwater, the older sea lion (22-25 years of age) showed hearing losses relative to the younger sea lion (13-16 years) that ranged from 10 dB at lower frequencies to 50 dB near the upper frequency limit. The older sea lions' hearing losses in air were consistent with those measured underwater. The older human (69 years) tested also showed losses relative to the younger human (22 years). These differences ranged from 15 dB at lower frequencies up to 35 dB at the highest frequency tested. The results obtained in this study document age-related hearing losses in sea lions and humans. The findings are consistent with data on presbycusis in other mammalian species, showing that maximum hearing loss occurs at the highest frequencies.

Apps for Hearing Science and Care.

Paglialonga, Alessia; Tognola, Gabriella; Pinciroli, Francesco

2015-09-01

Our research aims at the identification and assessment of applications (referred to as apps) in the hearing health care domain. This research forum article presents an overview of the current availability, affordability, and variety of hearing-related apps. The available apps were reviewed by searching on the leading platforms (iOS, Android, Windows Phone stores) using the keywords hearing, audiology, audio, auditory, speech, language, tinnitus, hearing loss, hearing aid, hearing sys tem, cochlear implant, implantable device, auditory training, hearing rehabilitation, and assistive technology/tool/device. O n the bas is of the offered services, apps were classified into 4 application domains: (a) screening and assessment, (b) intervention and rehabilitation, (c) education and information, and (d) assistive tools. A large variety of apps are available in the hearing health care domain. These cover a wide range of services for people with hearing or communication problems as well as for hearing professionals, families, or informal caregivers. This evolution can potentially bring along considerable advantages and improved outcomes in the field of hearing health care. Nevertheless, potential risks and threats (e.g., safety, quality, effectiveness, privacy, and regulation) should not be overlooked. Significant research—particularly in terms of assessment and guidance—is still needed for the informed, aware, and safe adoption of hearing-related apps by patients and professionals.

[Rehabilitative measures in hearing-impaired children].

Science.gov (United States)

von Wedel, H; von Wedel, U C; Zorowka, P

1991-12-01

On the basis of certain fundamental data on the maturation processes of the central auditory pathways in early childhood the importance of early intervention with hearing aids is discussed and emphasized. Pathological hearing, that is acoustical deprivation in early childhood will influence the maturation process. Very often speech development is delayed if diagnosis and therapy or rehabilitation are not early enough. Anamnesis, early diagnosis and clinical differential diagnosis are required before a hearing aid can be fitted. Selection criteria and adjustment parameters are discussed, showing that the hearing aid fitting procedure must be embedded in a complex matrix of requirements related to the development of speech as well as to the cognitive, emotional and social development of the child. As a rule, finding and preparing the "best" hearing aids (binaural fitting is obligatory) for a child is a long and often difficult process, which can only be performed by specialists who are pedo-audiologists. After the binaural fitting of hearing aids an intensive hearing and speech education in close cooperation between parents, pedo-audiologist and teacher must support the whole development of the child.

Coronary artery bypass grafting and sensorineural hearing loss, a cohort study

Directory of Open Access Journals (Sweden)

Ashraf Omer

2005-12-01

Full Text Available Abstract Background Sudden sensorineural hearing loss is routinely encountered by the otologist. The etiology is varied and often identifiable. One of the relatively less frequent causes is surgery. Apart from being an established entity with otological surgeries, sensorineural hearing loss has also been known to occur after non-otological procedures under general anesthesia. Commonest amongst these procedures is cardiopulmonary bypass, an association that has long been recognized. However, despite the proposition of diverse hypotheses in the past, the pathophysiology remains unclear. Methods The study is a prospective matched cohort study that will be carried out in Aga Khan University Hospital, Karachi, Pakistan. Participants among exposed would include all those patients who would be undergoing coronary artery bypass surgery in the hospital who fall under the criteria for inclusion. Unexposed group would comprise of patients undergoing a non-bypass procedure of similar duration under the same type of anesthesia who meet the selection criteria. Both these groups will undergo audiometric testing at our hospital on three different occasions during the course of this study. Initially before the procedure to test the baseline hearing capacity; then one week after the procedure to assess any changes in hearing ability following the surgery; and finally a third audiogram at six weeks follow-up to assess further changes in any hearing deficits noted during the second phase of testing. Certain variables including the subjects' demographics and those concerning the procedure itself will be noted and used later for risk factors analysis. A detailed past medical and surgical history will also be obtained. Data analysis would include calculation of relative risk and significance of the results, by running the chi-square test. Other statistical tests like Fisher exact test may then be employed to facilitate data interpretation. Continuous scale may then be

Public hearings and environmental management in Latin America

International Nuclear Information System (INIS)

Fischer de Lemos, Chelen

2002-01-01

The study attempts to review comparative environmental public hearings, regulation regions in four Latin America countries: Argentina, Brazil, Uruguay and Colombia. It seeks the similarities and differences, advances and limits from public participation on decision making and environmental management process. The main characteristics of the normative instruments are looking for the following aspects: who requests and who convokes the hearings, which are the objectives and the matters of the hearings, when they occur and which are its legal effects. Four summaries of public hearings are presented to illustrate the analysis. The analysis follows two approaches: the first one is based on the instrumental conception of the public hearings for social conflicts control and the second stress that new forms of subjectivity and participation can arise in the process of public hearings accomplishment

Autonomous motivation is associated with hearing aid adoption.

Ridgway, Jason; Hickson, Louise; Lind, Christopher

2015-07-01

To use the self-determination theory of motivation to investigate whether different forms of motivation were associated with adults' decisions whether or not to adopt hearing aids. A quantitative approach was used in this cohort study. Participants completed the treatment self-regulation questionnaire (TSRQ), which measured autonomous and controlled motivation for hearing aid adoption. Sociodemographic data and audiometric information were also obtained. Participants were 253 adults who had sought information about their hearing but had not consulted with a hearing professional. Participants were categorized as hearing aid adopters if they had been fitted with hearing aids 4-6 months after completing the TSRQ, and as non-adopters if they had not. Multivariate logistic regression was used to examine associations between autonomous and controlled motivation, sociodemographic and audiometric variables, and hearing aid adoption (n = 160). Three factors were significantly associated with increased hearing aid adoption when the influence of other variables was accounted for: autonomous motivation, perceived hearing difficulty, and poorer hearing. Controlled motivation was not found to influence hearing aid adoption. These empirical findings that link autonomous motivation to decisions of hearing help-seekers have implications for the ways practitioners may evaluate motivation and could inform discussions with clients about hearing aid adoption.

Auditory brainstem response screening for hearing loss in high risk neonates.

Science.gov (United States)

Watson, D R; McClelland, R J; Adams, D A

1996-07-01

The present paper reports the findings of a 7 year study evaluating the use of the auditory brainstem response (ABR) as the basis of a hearing screening procedure in a group of newborns at increased risk of hearing impairment. A Special Care Baby Unit (SCBU) population of 417 infants with diverse clinical backgrounds and treatment histories was tested for hearing impairment at birth using ABR audiometry. Some 332 passed the original screen at 30 dBnHL test level in both ears. Of the failure group, 18 did not survive and 32 had some degree of hearing impairment confirmed, nine of which were sensorineural in origin. An increased incidence of persistent middle ear disease was also noted in the failure group. A detailed operational analysis demonstrates that provided appropriate pass/fail criteria are adopted, the ABR technique offers excellent sensitivity and specificity for the detection of significant hearing loss in the test population. Furthermore, the study establishes that implementation of an ABR-based screening programme could reduce the average age at detection of permanent hearing loss by 7 months. A cost assessment shows that the introduction of such a targetted screening procedure could be done at a reasonable outlay.

2002-10-01

Washington State has experienced a striking increase in workers' compensation claims for hearing loss. This cross-sectional study examined noise exposures and hearing conservation practices in one industry with a high rate of hearing loss claims. We evaluated 10 representative foundries with personal noise dosimetry, management interviews, employee interviews, and existing audiometry. Noise levels routinely exceeded 85 dBA. All companies were out of compliance with hearing conservation regulations. Most employees with important findings on audiograms were not aware of their findings. There was a significant positive correlation between management-interview scores and worksite-average employee-interview scores (r = 0.70, P = 0.02). Companies where more effort is put into hearing conservation program activities can achieve a greater positive impact on employee awareness. However, there were broad deficiencies even in the better programs in this sample, suggesting that workers in this industry probably face a continuing substantial risk of occupational hearing loss.

Paths toward reclamation: therapeutic jurisprudence and the regulation of medical practitioners.

Science.gov (United States)

Freckelton, Ian; Flynn, Joanna

2004-08-01

Much about what used to be termed "disciplinary" investigations and hearings is being revisited in the modern era. Therapeutic jurisprudence enables informed and sensitive awareness to potentially therapeutic and counter-therapeutic effects of both investigations and hearings conducted by medical regulatory authorities. This article analyses key aspects of authorities' processes from the perspective of notifiers/complainants and practitioners. Using developments at the Victorian Medical Practitioners Board as a base, it addresses issues of both investigative procedures and decision-making at formal and informal hearings, as well as the ramifications of re-hearings for the integrity of peer review informed regulation. It argues that where reclamation of practitioners is possible (namely where impropriety is not of the most serious order), there is much that is constructive about a focus upon enhancement of performance and competence levels, rather than the traditional preoccupation with whether registered status needs to be affected as a result of practitioner conduct.

Working alliance, interpersonal trust and perceived coercion in mental health review hearings

Full Text Available Abstract Background There is some evidence that when mental health commitment hearings are held in accordance with therapeutic jurisprudence principles they are perceived as less coercive, and more just in their procedures leading to improved treatment adherence and fewer hospital readmissions. This suggests an effect of the hearing on therapeutic relationships. We compared working alliance and interpersonal trust in clinicians and forensic patients, whose continued detentions were reviewed by two different legal review bodies according to their legal category. Methods The hearings were rated as positive or negative by patients and treating psychiatrists using the MacArthur scales for perceived coercion, perceived procedural justice (legal and medical and for the impact of the hearing. We rated Global assessment of Function (GAF, Positive and Negative Symptom Scale (PANSS, Working Alliance Inventory (WAI and Interpersonal Trust in Physician (ITP scales six months before the hearing and repeated the WAI and ITP two weeks before and two weeks after the hearing, for 75 of 83 patients in a forensic medium and high secure hospital. Results Psychiatrists agreed with patients regarding the rating of hearings. Patients rated civil hearings (MHTs more negatively than hearings under insanity legislation (MHRBs. Those reviewed by MHTs had lower scores for WAI and ITP. However, post-hearing WAI and ITP scores were not different from baseline and pre-hearing scores. Using the receiver operating characteristic, baseline WAI and ITP scores predicted how patients would rate the hearings, as did baseline GAF and PANSS scores. Conclusions There was no evidence that positively perceived hearings improved WAI or ITP, but some evidence showed that negatively perceived hearings worsened them. Concentrating on functional recovery and symptom remission remains the best strategy for improved therapeutic relationships.

2015-01-01

Background We examined the association between self-reported hearing protection use at work and incidence of hearing shifts over a 5-year period. Methods Audiometric data from 19,911 workers were analyzed. Two hearing shift measures—OSHA standard threshold shift (OSTS) and high-frequency threshold shift (HFTS)—were used to identify incident shifts in hearing between workers’ 2005 and 2009 audiograms. Adjusted odds ratios were generated using multivariable logistic regression with multi-level modeling. Results The odds ratio for hearing shift for workers who reported never versus always wearing hearing protection was nonsignificant for OSTS (OR 1.23, 95% CI 0.92–1.64) and marginally significant for HFTS (OR 1.26, 95% CI 1.00–1.59). A significant linear trend towards increased risk of HFTS with decreased use of hearing protection was observed (P = 0.02). Conclusion The study raises concern about the effectiveness of hearing protection as a substitute for noise control to prevent noise-induced hearing loss in the workplace. Am. J. Ind.

[Hearing loss and idoneity--the segnalation of noise-induced hearing loss hearing Loss].

Science.gov (United States)

Albera, Roberto; Dagna, Federico; Cassandro, Claudia; Canale, Andrea

2011-01-01

Work idoneity in hearing loss must be related to working ability and evolution risks. Working ability is referred to the difficulties found in speech comprehension and in signals perception. As regards hearing loss evolution it is necessary to define if the subject is affected by conductive or neurosensorial hearing loss. In conductive hearing loss it is necessary to evaluate entity and frequential distribution of the deficit. In neurosensorial hearing loss it is necessary to distinguish between noise-induced hearing loss and extraprofessional hearing loss. In noise-induced hearing loss the evolution risk is high if the noise exposure is less than 10-15 years or the actual noise exposure is louder than the former. In case of extraprofessional hearing loss the evolution risk is higher in presbycusis, endolymphatic hydrops and toxic hearing loss. The necessity to report the presence on professionale noise-induced hearing loss arises if audiometric threshold is more than 25 dB at 0.5-1-2-3-4 kHz and if it is verified the professional origine of hearing loss.

2014-01-01

The aim of this study is to assess the impact of hearing status on age-related decrease in verbal short-term memory (STM) performance. This was done by administering a battery of verbal STM tasks to elderly and young adult participants matched for hearing thresholds, as well as to young normal-hearing control participants. The matching procedure allowed us to assess the importance of hearing loss as an explanatory factor of age-related STM decline. We observed that elderly participants and hearing-matched young participants showed equal levels of performance in all verbal STM tasks, and performed overall lower than the normal-hearing young control participants. This study provides evidence for recent theoretical accounts considering reduced hearing level as an important explanatory factor of poor auditory-verbal STM performance in older adults.

Full Text Available RA (rheumatoid arthritis is a chronic multisystem disease with a variety of systemic manifestations. One of these manifestations, is hearing disorder, so study of the relation between RA and hearing disorders is seem important. This was a case-control study which has done from December 2004 to August 2006. This study compared 50 patients with RA, with age, sex and job-matched as control. Audiometric tests in different frequencies show that hearing threshold in high frequencies specially in 8000 Hz had a significant difference between two groups, also acoustic reflexes were absent in case groups and had significant difference between two groups too. The evaluation of sensory neural hearing loss showed that this hearing loss is sensory not neural. Based on this study, frequent evaluation of audiometric tests is recommended for controlling hearing disorders by therapeutic and rehabilitation procedures in RA patients.

To develop a tool for use in hearing screening and to evaluate the patient journey towards hearing rehabilitation, responses to the hearing aid rehabilitation questionnaire scales aid stigma, pressure, and aid unwanted addressing respectively hearing aid stigma, experienced pressure from others; perceived hearing aid benefit were evaluated with item response theory. The sample was comprised of 212 persons aged 55 years or more; 63 were hearing aid users, 64 with and 85 persons without hearing impairment according to guidelines for hearing aid reimbursement in the Netherlands. Bias was investigated relative to hearing aid use and hearing impairment within the differential test functioning framework. Items compromising model fit or demonstrating differential item functioning were dropped. The aid stigma scale was reduced from 6 to 4, the pressure scale from 7 to 4, and the aid unwanted scale from 5 to 4 items. This procedure resulted in bias-free scales ready for screening purposes and application to further understand the help-seeking process of the hearing impaired. PMID:28028428

ASPECTS OF CRIMINALISTICS TACTICS RELATED TO WITNESS HEARING

Directory of Open Access Journals (Sweden)

Nicolae Mărgărit

2017-12-01

Full Text Available The article analyses some aspects related to witness statements, with regard to the actual tactics of hearing witnesses and the hearing of child witnesses. Judicial practice has well shown that giving evidence is the most important phase in the course of the activity carried out by judicial bodies, being the way for determining the facts, for finding the truth in the case referred for settlement. Giving the evidence in a correct and complete way, the value of the administered evidence and its correct and lawful evaluation are decisive for the judicial bodies to come to an intimate belief with regard to the factual reality on which the solution they pronounce should be based, the lawfulness itself of court rulings and other solutions given by the judicial bodies being dependant on these elements. In order to obtain the evidence and make the most of it in a criminal trial, legal activities or operations are necessary to discover it and to present it in a form which is perceptible for the judicial bodies, an aspect which is accomplished by legal means of evidence. Criminal doctrine and judicial practice alike have determined that for finding the truth in a criminal trial, besides the statements made by the suspect or the accused, the statements of the other parties in the trial have an appreciable contribution too. In this context, the contribution of Criminalistics – the science of crime investigation – to establishing the facts in a criminal trial is especially noticeable with the conclusions of forensic examinations and findings. The study put forward reveals some aspects of criminalistics tactics related to witness hearing in a criminal trial, as well as that the result of the investigation depends on how the activity of witness hearing is prepared and the compliance with all procedural rules. At the same time, as Criminalistics supports the witness hearing activity, it develops a particular tactical hearing procedure, starting precisely

Noise-induced hearing loss

Full Text Available Noise-induced hearing loss (NIHL still remains a problem in developed countries, despite reduced occupational noise exposure, strict standards for hearing protection and extensive public health awareness campaigns. Therefore NIHL continues to be the focus of noise research activities. This paper summarizes progress achieved recently in our knowledge of NIHL. It includes papers published between the years 2008-2011 (in English, which were identified by a literature search of accessible medical and other relevant databases. A substantial part of this research has been concerned with the risk of NIHL in the entertainment sector, particularly in professional, orchestral musicians. There are also constant concerns regarding noise exposure and hearing risk in "hard to control" occupations, such as farming and construction work. Although occupational noise has decreased since the early 1980s, the number of young people subject to social noise exposure has tripled. If the exposure limits from the Noise at Work Regulations are applied, discotheque music, rock concerts, as well as music from personal music players are associated with the risk of hearing loss in teenagers and young adults. Several recent research studies have increased the understanding of the pathomechanisms of acoustic trauma, the genetics of NIHL, as well as possible dietary and pharmacologic otoprotection in acoustic trauma. The results of these studies are very promising and offer grounds to expect that targeted therapies might help prevent the loss of sensory hair cells and protect the hearing of noise-exposed individuals. These studies emphasize the need to launch an improved noise exposure policy for hearing protection along with developing more efficient norms of NIHL risk assessment.

[Progressive noise induced hearing loss caused by hearing AIDS, a dilemma for the worker and the expert alike].

Science.gov (United States)

Feldmann, H

2001-12-01

Investigating cases of noise induced hearing loss the expert is often confronted with the situation that the hearing loss is progressive although the noise exposure has been reduced to almost non-damaging levels. Other causes such as age, hereditary deafness, head injuries, blasts, internal diseases can be excluded. Hearing aids as sources of damaging noise? By consulting the protocol of the hearing-aid acoustician and by own examinations the expert should obtain the following data: loudness level that yields best discrimination score of speech; level of discomfort for tones and speech, discrimination score that is achieved under free field condition with a speech level of 65 dB, using the hearing aids. Furthermore he should explore the circumstances under which the hearing aids are used: how many hours per day, at what occasions etc.? It is likely that in using the hearing aids they are adjusted to emit an intensity level identical to the one yielding the optimal discrimination score. If this e. g. is 100 dB and the hearing aids are used for 2 hours per day this would be equivalent to an exposure to industrial noise of 94 dB (A) for 8 hours daily without ear protection. Among all individuals working under industrial noise exposure today only about 1 - 2 % having unusually vulnerable inner ears will suffer a noise induced hearing loss. On the other hand workers in industrial noise are accustomed to loud noise levels, usually have a raised threshold of discomfort and therefore are likely to adjust their hearing aids to such high intensities. The expert will have to decide whether in an individual case the industrial noise exposure or the use of the hearing aids is the dominant risk for further damage. The consequences in respect to the regulations of the workers' health insurance are discussed.

2015-01-01

To examine the association of cognitive function, age, and hearing loss with clinically assessed hearing aid benefit in older hearing-impaired persons. Hearing aid benefit was assessed using objective measures regarding speech recognition in quiet and noisy environments as well as a subjective measure reflecting everyday situations captured using a standardized questionnaire. A broad range of general cognitive functions such as attention, memory, and intelligence were determined using different neuropsychological tests. Linear regression analyses were conducted with the outcome of the neuropsychological tests as well as age and hearing loss as independent variables and the benefit measures as dependent variables. Thirty experienced older hearing aid users with typical age-related hearing impairment participated. Most of the benefit measures revealed that the participants obtained significant improvement with their hearing aids. Regression models showed a significant relationship between a fluid intelligence measure and objective hearing aid benefit. When individual hearing thresholds were considered as an additional independent variable, hearing loss was the only significant contributor to the benefit models. Lower cognitive capacity - as determined by the fluid intelligence measure - was significantly associated with greater hearing loss. Subjective benefit could not be predicted by any of the variables considered. The present study does not give evidence that hearing aid benefit is critically associated with cognitive function in experienced hearing aid users. However, it was found that lower fluid intelligence scores were related to higher hearing thresholds. Since greater hearing loss was associated with a greater objective benefit, these results strongly support the advice of using hearing aids regardless of age and cognitive function to counter hearing loss and the adverse effects of age-related hearing impairment. Still, individual cognitive capacity might

Improving Mobile Phone Speech Recognition by Personalized Amplification: Application in People with Normal Hearing and Mild-to-Moderate Hearing Loss.

Kam, Anna Chi Shan; Sung, John Ka Keung; Lee, Tan; Wong, Terence Ka Cheong; van Hasselt, Andrew

In this study, the authors evaluated the effect of personalized amplification on mobile phone speech recognition in people with and without hearing loss. This prospective study used double-blind, within-subjects, repeated measures, controlled trials to evaluate the effectiveness of applying personalized amplification based on the hearing level captured on the mobile device. The personalized amplification settings were created using modified one-third gain targets. The participants in this study included 100 adults of age between 20 and 78 years (60 with age-adjusted normal hearing and 40 with hearing loss). The performance of the participants with personalized amplification and standard settings was compared using both subjective and speech-perception measures. Speech recognition was measured in quiet and in noise using Cantonese disyllabic words. Subjective ratings on the quality, clarity, and comfortableness of the mobile signals were measured with an 11-point visual analog scale. Subjective preferences of the settings were also obtained by a paired-comparison procedure. The personalized amplification application provided better speech recognition via the mobile phone both in quiet and in noise for people with hearing impairment (improved 8 to 10%) and people with normal hearing (improved 1 to 4%). The improvement in speech recognition was significantly better for people with hearing impairment. When the average device output level was matched, more participants preferred to have the individualized gain than not to have it. The personalized amplification application has the potential to improve speech recognition for people with mild-to-moderate hearing loss, as well as people with normal hearing, in particular when listening in noisy environments.

2003-10-01

A behavioral response paradigm was used to measure pure-tone audiograms for two white whales (Delphinapterus leucas). Tests were conducted over a 20 month period at the Point Defiance Zoo and Aquarium, in Tacoma, Washington. Subjects consisted of two males, aged 8-10 and 9-11 during the course of the study. Subjects were born in an oceanarium and had been housed together for all of their lives. Hearing thresholds were measured using a modified up/down staircase procedure and acoustic response paradigm where subjects were trained to whistle in response to hearing test tones and to remain quiet otherwise. Test frequencies ranged from approximately 2 to 130 kHz. Best sensitivities ranged from 40 to 50 dB re: 1 Pa. Both subjects had traditional U-shaped mammalian audiograms; however, one subject exhibited significant high-frequency hearing loss, above approximately 37 kHz. The experimental setup and procedure will be presented and the measured hearing thresholds compared to those previously measured in white whales. The potential role of ototoxic antibiotics in the observed hearing loss will be discussed. [Work supported by ONR Marine Mammal S&T Program and the U.S. Navy CNO(N45).

Licensing procedures for Low-Level Waste disposal facilities

International Nuclear Information System (INIS)

Roop, R.D.; Van Dyke, J.W.

1985-09-01

This report describes the procedures applicable to siting and licensing of disposal facilities for low-level radioactive wastes. Primary emphasis is placed on those procedures which are required by regulations, but to the extent possible, non-mandatory activities which will facilitate siting and licensing are also considered. The report provides an overview of how the procedural and technical requirements for a low-level waste (LLW) disposal facility (as defined by the Nuclear Regulatory Commission's Rules 10 CFR Parts 2, 51, and 61) may be integrated with activities to reduce and resolve conflict generated by the proposed siting of a facility. General procedures are described for site screening and selection, site characterization, site evaluation, and preparation of the license application; specific procedures for several individual states are discussed. The report also examines the steps involved in the formal licensing process, including docketing and initial processing, preparation of an environmental impact statement, technical review, hearings, and decisions. It is concluded that development of effective communication between parties in conflict and the utilization of techniques to manage and resolve conflicts represent perhaps the most significant challenge for the people involved in LLW disposal in the next decade. 18 refs., 6 figs

Item response theory applied to factors affecting the patient journey towards hearing rehabilitation

Directory of Open Access Journals (Sweden)

Michelene Chenault

2016-11-01

Full Text Available To develop a tool for use in hearing screening and to evaluate the patient journey towards hearing rehabilitation, responses to the hearing aid rehabilitation questionnaire scales aid stigma, pressure, and aid unwanted addressing respectively hearing aid stigma, experienced pressure from others; perceived hearing aid benefit were evaluated with item response theory. The sample was comprised of 212 persons aged 55 years or more; 63 were hearing aid users, 64 with and 85 persons without hearing impairment according to guidelines for hearing aid reimbursement in the Netherlands. Bias was investigated relative to hearing aid use and hearing impairment within the differential test functioning framework. Items compromising model fit or demonstrating differential item functioning were dropped. The aid stigma scale was reduced from 6 to 4, the pressure scale from 7 to 4, and the aid unwanted scale from 5 to 4 items. This procedure resulted in bias-free scales ready for screening purposes and application to further understand the help-seeking process of the hearing impaired.

A Browser-Server-Based Tele-audiology System That Supports Multiple Hearing Test Modalities.

Science.gov (United States)

Yao, Jianchu Jason; Yao, Daoyuan; Givens, Gregg

2015-09-01

Millions of global citizens suffering from hearing disorders have limited or no access to much needed hearing healthcare. Although tele-audiology presents a solution to alleviate this problem, existing remote hearing diagnosis systems support only pure-tone tests, leaving speech and other test procedures unsolved, due to the lack of software and hardware to enable communication required between audiologists and their remote patients. This article presents a comprehensive remote hearing test system that integrates the two most needed hearing test procedures: a pure-tone audiogram and a speech test. This enhanced system is composed of a Web application server, an embedded smart Internet-Bluetooth(®) (Bluetooth SIG, Kirkland, WA) gateway (or console device), and a Bluetooth-enabled audiometer. Several graphical user interfaces and a relational database are hosted on the application server. The console device has been designed to support the tests and auxiliary communication between the local site and the remote site. The study was conducted at an audiology laboratory. Pure-tone audiogram and speech test results from volunteers tested with this tele-audiology system are comparable with results from the traditional face-to-face approach. This browser-server-based comprehensive tele-audiology offers a flexible platform to expand hearing services to traditionally underserved groups.

How to quantify binaural hearing in patients with unilateral hearing using hearing implants.

Science.gov (United States)

Snik, Ad; Agterberg, Martijn; Bosman, Arjan

2015-01-01

Application of bilateral hearing devices in bilateral hearing loss and unilateral application in unilateral hearing loss (second ear with normal hearing) does not a priori lead to binaural hearing. An overview is presented on several measures of binaural benefits that have been used in patients with unilateral or bilateral deafness using one or two cochlear implants, respectively, and in patients with unilateral or bilateral conductive/mixed hearing loss using one or two percutaneous bone conduction implants (BCDs), respectively. Overall, according to this overview, the most significant and sensitive measure is the benefit in directional hearing. Measures using speech (viz. binaural summation, binaural squelch or use of the head shadow effect) showed minor benefits, except for patients with bilateral conductive/mixed hearing loss using two BCDs. Although less feasible in daily practise, the binaural masking level difference test seems to be a promising option in the assessment of binaural function. © 2015 S. Karger AG, Basel.

Part nine of the hearing record covers testimony pertaining to activities of DOE and the Nuclear Regulatory Commission (NRC). Seven witnesses from DOE, including representatives of the Richland and Savannah River facilities, testified on the safety of US reactors in response to concerns about the Chernobyl accident. At issue was whether US research or power reactors are vulnerable to a similar kind of accident. Witnesses noted DOE's safety record, its recent reviews of oversight procedures, and modifications to correct possible weaknesses in those procedures. Technical safety appraisals at Savannah River were made earlier than originally planned, and other studies will be conducted to ensure that design and engineering will minimize the possibility of an accident. NRC Commissioners and regulators testified at the second day of hearings to describe its efforts to understand what happened at Chernobyl and to outline the differences between the Soviet and US reactors

Remote hearing aid fitting: Tele-audiology in the context of Brazilian Public Policy

Science.gov (United States)

Penteado, Silvio Pires; Ramos, Sueli de Lima; Battistella, Linamara Rizzo; Marone, Silvio Antonio Monteiro; Bento, Ricardo Ferreira

2012-01-01

Summary Introduction: Currently, the Brazilian government has certificated nearly 140 specialized centers in hearing aid fittings through the Brazilian National Health System (SUS). Remote fitting through the Internet can allow a broader and more efficient coverage with a higher likelihood of success for patients covered by the SUS, as they can receive fittings from their own homes instead of going to the few and distant specialized centers. Aim: To describe a case of remote fitting between 2 cities, with revision of the literature. Method: Computer gears, a universal interface, and hearing aids were used. Case study: An audiologist located in a specialized center introduced a new hearing aid and its fitting procedure to a remote center (200 km away). The specialized center helped the remote center in fitting a hearing aid in 2 patients, and performed fitting in one of its own patients. The whole process was done through the Internet with audio and video in real time. Results: Three patients were fitted remotely. Three audiologists were remotely trained on how to fit the hearing aids. Conclusions: Remote fitting of hearing aids is possible through the Internet, as well as further supplying technical training to a remote center about the fitting procedures. Such a technological approach can help the government advance public policies on hearing rehabilitation, as patients can be motivated about maintaining their use of hearing aids with the option to ask for help in the comfort of their own homes.

Detection threshold for sound distortion resulting from noise reduction in normal-hearing and hearing-impaired listeners.

Science.gov (United States)

Brons, Inge; Dreschler, Wouter A; Houben, Rolph

2014-09-01

Hearing-aid noise reduction should reduce background noise, but not disturb the target speech. This objective is difficult because noise reduction suffers from a trade-off between the amount of noise removed and signal distortion. It is unknown if this important trade-off differs between normal-hearing (NH) and hearing-impaired (HI) listeners. This study separated the negative effect of noise reduction (distortion) from the positive effect (reduction of noise) to allow the measurement of the detection threshold for noise-reduction (NR) distortion. Twelve NH subjects and 12 subjects with mild to moderate sensorineural hearing loss participated in this study. The detection thresholds for distortion were determined using an adaptive procedure with a three-interval, two-alternative forced-choice paradigm. Different levels of distortion were obtained by changing the maximum amount of noise reduction. Participants were also asked to indicate their preferred NR strength. The detection threshold for overall distortion was higher for HI subjects than for NH subjects, suggesting that stronger noise reduction can be applied for HI listeners without affecting the perceived sound quality. However, the preferred NR strength of HI listeners was closer to their individual detection threshold for distortion than in NH listeners. This implies that HI listeners tolerate fewer audible distortions than NH listeners.

The regulatory practice of the French financial regulator, 2006-2011. From substantive to procedural financial regulation?

Directory of Open Access Journals (Sweden)

Thierry Kirat

2015-11-01

Full Text Available Fraud and misconduct in financial markets have recently become a key regulatory issue against the backdrop of the financial crisis. This paper investigates the sanctions policy and practices of the French financial regulator, Autorité des Marchés Financiers (AMF. It argues that, over time, the AMF has shifted from substantive to procedural regulation of finance. This shift consists in departing from sanctions based on observed outcomes in the market and, instead, assessing how the internal organizational schemes of financial firms actually perform. The AMF’s new policy and practice involves a process of legalization of organizations; it also evidences a tendency to delegate regulation to financial firms themselves

Reflectance Measures from Infant Ears With Normal Hearing and Transient Conductive Hearing Loss.

Science.gov (United States)

Voss, Susan E; Herrmann, Barbara S; Horton, Nicholas J; Amadei, Elizabeth A; Kujawa, Sharon G

2016-01-01

The objective is to develop methods to utilize newborn reflectance measures for the identification of middle-ear transient conditions (e.g., middle-ear fluid) during the newborn period and ultimately during the first few months of life. Transient middle-ear conditions are a suspected source of failure to pass a newborn hearing screening. The ability to identify a conductive loss during the screening procedure could enable the referred ear to be either (1) cleared of a middle-ear condition and recommended for more extensive hearing assessment as soon as possible, or (2) suspected of a transient middle-ear condition, and if desired, be rescreened before more extensive hearing assessment. Reflectance measurements are reported from full-term, healthy, newborn babies in which one ear referred and one ear passed an initial auditory brainstem response newborn hearing screening and a subsequent distortion product otoacoustic emission screening on the same day. These same subjects returned for a detailed follow-up evaluation at age 1 month (range 14 to 35 days). In total, measurements were made on 30 subjects who had a unilateral refer near birth (during their first 2 days of life) and bilateral normal hearing at follow-up (about 1 month old). Three specific comparisons were made: (1) Association of ear's state with power reflectance near birth (referred versus passed ear), (2) Changes in power reflectance of normal ears between newborn and 1 month old (maturation effects), and (3) Association of ear's newborn state (referred versus passed) with ear's power reflectance at 1 month. In addition to these measurements, a set of preliminary data selection criteria were developed to ensure that analyzed data were not corrupted by acoustic leaks and other measurement problems. Within 2 days of birth, the power reflectance measured in newborn ears with transient middle-ear conditions (referred newborn hearing screening and passed hearing assessment at age 1 month) was significantly

Coutinho, M B; Marques, C; Mendes, G J; Gonçalves, C

2015-11-01

To report a case of successful bone-anchored hearing aid implantation in an adult patient with type III osteogenesis imperfecta, which is commonly regarded as a contraindication to this procedure. A 45-year-old man with type III osteogenesis imperfecta presented with mixed hearing loss. There was a mild sensorineural component in both ears, with an air-bone gap between 45 and 50 dB HL. He was implanted with a bone-anchored hearing aid. The audiological outcome was good, with no complications and good implant stability (as measured by resonance frequency analysis). To our knowledge, this is the first recorded case of bone-anchored hearing aid implantation in a patient with osteogenesis imperfecta.

Assessment of hearing and hearing disorders in rock/jazz musicians.

Kähärit, Kim; Zachau, Gunilla; Eklöf, Mats; Sandsjö, Leif; Möller, Claes

2003-07-01

The aim of this study was to assess hearing and hearing disorders among rock/jazz musicians. One hundred and thirty-nine (43 women and 96 men) musicians participated. The results are based on pure-tone audiometry and questionnaire responses. According to our definition of hearing loss, tinnitus, hyperacusis, distortion and/or diplacusis as hearing disorders, we found disorders in 74%, of the rock/jazz musicians studied. Hearing loss, tinnitus and hyperacusis were most common, and the latter two were found significantly more frequently than in different reference populations. The women showed bilateral, significantly better hearing thresholds at 3-6 kHz than the men. Hyperacusis, and the combination of both hyperacusis and tinnitus, were found to be significantly more frequent among women than among men. Hearing loss and tinnitus were significantly more common among men than among women. It is important to evaluate all kinds of hearing problems (other than hearing loss) in musicians, since they represent an occupational group especially dependent on optimal, functional hearing. On the basis of our results, we suggest that hearing problems such as tinnitus, hyperacusis, distortion and/or diplacusis should, in addition to hearing loss, be defined as hearing disorders.

Teresa María Lizcano Tejado

2013-09-01

Full Text Available Hearing loss is a significant public health problem. The incidence is difficult to establish because of the lack of data in people under age three, but is estimated about 1 per thousand for severe and profound hearing loss.A cochlear implant (CI is a device that converts sounds into electrical energy that triggers a sensation of hearing. The IC is indicated in patients with severe bilateral sensorineural hearing loss with null or poor benefit use of hearing aids.The general objective of this project is to understand the experiences of adult patients with severe-profound sensorineural hearing loss with IC postlingually throughout the implementation process.A personal vision of those implemented will allow us to learn how to face the possibility to hear and interact with their environment, applying this information to improve health care provided to them and identifying those areas where such assistance should be improved. Also allow us to compare the initial expectations and have been achieved, creating realistic expectations for future candidates.For its development we have designed a qualitative study, based on the principles and procedures of grounded theory, semistructured interviews, participant observation and discussion groups.The data will be analyzed using the software Nudist ViVo 9.

Emotional functioning plays a crucial role in the social development of children and adolescents. We examined the extent to which emotion control was related to the quality of friendships in pre-adolescents with and without hearing loss. We tested 350 pre-adolescents (75 deaf/hard of hearing in mainstream education (DHHm), 48 deaf/hard of hearing in special education (DHHs), and 227 hearing) through self-report. Outcomes confirmed a positive association between emotion control and positive friendships for all groups, with one notable exception: more approach strategies for emotion regulation were associated with more negative friendship features in the DHHs group. In addition, the DHHm group demonstrated high levels of emotion control, while their levels of positive friendship features were still lower compared to the hearing group.

Study Protocol for the Preschooler Regulation of Emotional Stress (PRES Procedure

Directory of Open Access Journals (Sweden)

Livio Provenzi

2017-09-01

Full Text Available Background: Emotional stress regulation (ESR rapidly develops during the first months of age and includes different behavioral strategies which largely contribute to children’s behavioral and emotional adjustment later in life. The assessment of ESR during the first years of life is critical to identify preschool children who are at developmental risk. Although ESR is generally included in larger temperament batteries [e.g., the Laboratory Temperament Assessment Battery (Lab-TAB], there is no standardized observational procedure to specifically assess and measure ESR in preschool aged children.Aim: Here, we describe the development of an observational procedure to assess ESR in preschool aged children [i.e., the Preschooler Regulation of Emotional Stress (PRES Procedure] and the related coding system.Methods: Four Lab-TAB emotional stress episodes (i.e., the Stranger, the Perfect Circle, the Missing Sticker, and the Transparent Box have been selected. Independent coders developed a list of ESR codes resulting in two general indexes (i.e., active engagement and stress level and five specific indexes (i.e., anger, control, fear, inhibition, sadness. Finally, specific actions have been planned to assess the validity and the coding system reliability of PRES procedure.Ethics and Dissemination: The study has been approved by the Ethical Committee of the Scientific Institute IRCCS Eugenio Medea, Bosisio Parini (Italy. The PRES validation and reliability assessment as well as its use with healthy and at-risk populations of preschool children will be object of future scientific publications and international conference presentations.

Prevalence of hearing loss and accuracy of self-report among factory workers.

2011-01-01

Noise represents one of the most common occupational health hazards. A Healthy People 2020 objective aims to reduce hearing loss in the noise-exposed public. The purpose of this study was to describe and compare perceived and measured hearing, and to determine the prevalence of hearing loss among a group of factory workers. Data collected as part of an intervention study promoting hearing protector use among workers at an automotive factory in the Midwest were used. Plant employees (n=2691) provided information regarding their perceived hearing ability, work role, and other demographics. The relationships among audiograms, a single-item measure of perceived hearing ability, and demographic data were explored using chi-square, McNemar's test, Mann-Whitney U-test, sensitivity, and specificity. The prevalence of hearing loss among noise-exposed factory workers was 42% (where hearing loss was defined as >25 dB loss at the OSHA-recommended frequencies of 2, 3, and 4 kHz in either ear). However, 76% of workers reported their hearing ability as excellent or good. The difference in perceived hearing ability was significant at each tested frequency between those with and without measured hearing loss. Self-reported hearing ability was poorly related to results of audiometry. Although this group of workers was employed in a regulated environment and served by a hearing conservation program, hearing loss was highly prevalent. These findings, together with national prevalence estimates, support the need for evaluation of hearing conservation programs and increased attention to the national goal of reducing adult hearing loss.

Surgical Procedures for External Auditory Canal Carcinoma and the Preservation of Postoperative Hearing

Directory of Open Access Journals (Sweden)

Hiroshi Hoshikawa

2012-01-01

Full Text Available Carcinoma of the external auditory canal (EAC is an unusual head and neck malignancy. The pathophysiology of these tumors is different from other skin lesions because of their anatomical and functional characteristics. Early-stage carcinoma of the EAC can be generally cured by surgical treatment, and reconstruction of the EAC with a tympanoplasty can help to retain hearing, thus improving the patients’ quality of life. In this study, we present two cases of early-stage carcinoma of the EAC treated by canal reconstruction using skin grafts after lateral temporal bone resection. A rolled-up skin graft with a temporal muscle flap was useful for keeping the form and maintaining the postoperative hearing. An adequate size of the skin graft and blood supply to the graft bed are important for achieving a successful operation.

Full Text Available Objective: The aim of this study was to examine the effectiveness of group training of procedural emotion regulation strategies in cognitive coping of individuals suffering substance abuse. Method: A quasi-experimental design along with pretest-posttest and control group was used for this study. Then, 16 patients suffering substance abuse were selected through convenience sampling and were randomly assigned to two control and experimental groups. The experimental group received 10 sessions of group training of procedural emotion regulation strategies while the control group received no treatment. Both groups before and after the treatment completed the Persian version of cognitive emotion regulation questionnaire (Hasani, 2011. Results: The results showed that group training of e procedural motion regulation strategies leads to a reduction in maladaptive strategies such as self-blame, rumination, catastrophizing, and other-blame and an increase in adaptive strategies such as refocus on planning, positive reappraisal, and perspective development. Conclusion: Training of procedural emotion regulation strategies via the reduction of maladaptive and increase of adaptive cognitive emotion regulation strategies can provide the opportunity for the improvement and non-return to substance abuse.

There is converging evidence for altered audiovisual integration abilities in hearing-impaired individuals and those with profound hearing loss who are provided with cochlear implants, compared to normal-hearing adults. Still, little is known on the effects of hearing aid use on audiovisual integration in mild hearing loss, although this constitutes one of the most prevalent conditions in the elderly and, yet, often remains untreated in its early stages. This study investigated differences in the strength of audiovisual integration between elderly hearing aid users and those with the same degree of mild hearing loss who were not using hearing aids, the non-users, by measuring their susceptibility to the sound-induced flash illusion. We also explored the corresponding window of integration by varying the stimulus onset asynchronies. To examine general group differences that are not attributable to specific hearing aid settings but rather reflect overall changes associated with habitual hearing aid use, the group of hearing aid users was tested unaided while individually controlling for audibility. We found greater audiovisual integration together with a wider window of integration in hearing aid users compared to their age-matched untreated peers. Signal detection analyses indicate that a change in perceptual sensitivity as well as in bias may underlie the observed effects. Our results and comparisons with other studies in normal-hearing older adults suggest that both mild hearing impairment and hearing aid use seem to affect audiovisual integration, possibly in the sense that hearing aid use may reverse the effects of hearing loss on audiovisual integration. We suggest that these findings may be particularly important for auditory rehabilitation and call for a longitudinal study.

Full Text Available The present study investigates the hemispheric contributions of neuronal reorganization following early single-sided hearing (unilateral deafness. The experiments were performed on ten cats from our colony of deaf white cats. Two were identified in early hearing screening as unilaterally congenitally deaf. The remaining eight were bilaterally congenitally deaf, unilaterally implanted at different ages with a cochlear implant. Implanted animals were chronically stimulated using a single-channel portable signal processor for two to five months. Microelectrode recordings were performed at the primary auditory cortex under stimulation at the hearing and deaf ear with bilateral cochlear implants. Local field potentials (LFPs were compared at the cortex ipsilateral and contralateral to the hearing ear. The focus of the study was on the morphology and the onset latency of the LFPs. The data revealed that effects of hearing experience were more pronounced when stimulating the hearing ear. With respect to morphology of LFPs, pronounced hemisphere-specific effects were observed. Morphology of amplitude-normalized LFPs for stimulation of the deaf and the hearing ear was similar for responses recorded at the same hemisphere. However, when comparisons were performed between the hemispheres, the morphology was more dissimilar even though the same ear was stimulated. This demonstrates hemispheric specificity of some cortical adaptations irrespective of the ear stimulated. The results suggest a specific adaptation process at the hemisphere ipsilateral to the hearing ear, involving specific (down-regulated inhibitory mechanisms not found in the contralateral hemisphere. Finally, onset latencies revealed that the sensitive period for the cortex ipsilateral to the hearing ear is shorter than that for the contralateral cortex. Unilateral hearing experience leads to a functionally-asymmetric brain with different neuronal reorganizations and different sensitive

Research shows that many older children and teenagers who have mild to moderately severe sensorineural hearing loss do not use their hearing instruments during all waking hours. A variety of reasons may contribute toward this problem, including concerns about cosmetics associated with hearing aid use and the inconvenience of daily maintenance associated with hearing instruments. Extended-wear hearing instruments are inserted into the wearer's ear canal by an audiologist and are essentially invisible to outside observers. The goal of this study was to evaluate the potential benefits and limitations associated with use of extended-wear hearing instruments in a group of children with hearing loss. A two-way repeated measures design was used to examine performance differences obtained with the participants' daily-wear hearing instruments versus that obtained with extended-wear hearing instruments. Sixteen children, ages 10-17 yr old, with sensorineural hearing loss ranging from mild to moderately severe. Probe microphone measures were completed to evaluate the aided output of device. Behavioral test measures included word recognition in quiet, sentence recognition in noise, aided warble-tone thresholds, and psychophysical loudness scaling. Questionnaires were also administered to evaluate subjective performance with each hearing technology. Data logging suggested that many participants were not using their daily-wear hearing instruments during all waking hours (mean use was less than 6 h/day). Real ear probe microphone measurements indicated that a closer fit to the Desired Sensation Level Version 5 prescriptive targets was achieved with the children's daily-wear instruments when compared to the extended-wear instruments. There was no statistically significant difference in monosyllabic word recognition at 50 or 60 dBA obtained with the two hearing technologies. Sentence recognition in noise obtained with use of the extended-wear devices was, however, significantly

Dr. Ali Asghar Kakojoibari

2011-06-01

Full Text Available Background and Aim: listening, speaking, reading and writing are considered the lingual skills. These skills are in direct relation with each other. Listening is the first skill learnt by the individual through development. If damaged by hearing impairment, listening can cause serious defect to lingual skills. The goal of our research was to study the effect of hearing loss on reading literacy in hearing impairment students in comparison with normal hearing students.Methods: Study was performed using the examination booklets of Progress in International Reading Literacy Study (PIRLS 2001. 119 hearing impairment students of 4th grade primary school, last year guidance school, and last year high school levels in schools providing exceptional student education were included. These individuals were compared to 46 normal hearing students of 4th grade primary school of ordinary schools. Comparative statistical analysis was performed using t-test.Results: Reading literacy and literal contents understanding was shown to have a significant difference between normal hearing and whole hearing impaired student (p<0.05, except the ones in high school level with moderate hearing loss. There was also seen a significant difference between normal hearing and hearing impairment students in understanding of information contents (p=0.03.Conclusion: Hearing loss has a negative effect on reading literacy. Consequently, curriculum change and evolution of educational programs in exceptional centers is needed, in order to promote reading literacy and to enhance rest hearing

Bone-anchored hearing aid (BAHA: indications, functional results, and comparison with reconstructive surgery of the ear

Directory of Open Access Journals (Sweden)

Bento, Ricardo Ferreira

2012-01-01

Full Text Available Introduction: The bone-anchored hearing aid (BAHA is a bone conduction hearing device that transmits sound directly into the inner ear. It is mainly used in patients with conductive hearing loss associated with aural atresia, but it is also used in those with mixed and sensorineural hearing loss. Goals: To review the main indications for BAHA, to analyze the audiometric results and its benefits for patients and compare them with other treatment modalities, and to compare the literature data with our sample of 13 patients. Method: The research was performed using a database covering works in English, Spanish, and Portuguese, with no limitations in the years when the procedures were performed. We compared the literature data with our results for the 13 patients who underwent BAHA implantation between the years 2000 and 2009. Results: Most of the studies showed that BAHA has great advantages over reconstructive surgery in terms of hearing results, complications, and disease recurrence. The postoperative results for our 13 patients were satisfactory and comparable with the results from the literature, with closure of the air-bone gap in 7 patients and achieving an air-bone gap of 10 dB in 6 patients. No postoperative complications were observed. Conclusion: BAHA is a better treatment option than reconstructive surgery for patients with bilateral deafness. It is a relatively simple surgical procedure with few complications and good hearing results. Recent studies have examined its use in conductive and unilateral sensorineural hearing loss.

The objective of this study was to compare the timing of hearing aid (HA) acquisition between adults in rural and urban communities. We hypothesized that time of acquisition of HA after onset of hearing loss is greater in rural adults compared with urban adults. Secondary objectives included assessment of socioeconomic/educational status and impact of hearing loss and hearing rehabilitation of urban and rural HA recipients. Cross-sectional questionnaire survey. We assessed demographics, timing of HA fitting from onset of hearing loss, and impact of hearing impairment in 336 adult HA recipients (273 urban, 63 rural) from a tertiary referral center. Amplification benefit was assessed using the International Outcome Inventory for Hearing Aids (IOI). The time to HA acquisition was greater for rural participants compared to urban participants (19.1 vs. 25.7 years, P = 0.024) for those with untreated hearing loss for at least 8 years. Age at hearing loss onset was correlated with time to HA acquisition (P = -0.54, P hearing specialists (68 vs. 32 minutes, P Hearing impairment caused job performance difficulty in 60% of all participants. Rural adults are at risk for delayed HA acquisition, which may be related to distance to hearing specialists. Further research is indicated to investigate barriers to care and expand access for vulnerable populations. 4.

Several recent investigations support the use of frequency modulation (FM) systems in children with normal hearing and auditory processing or listening disorders such as those diagnosed with auditory processing disorders, autism spectrum disorders, attention-deficit hyperactivity disorder, Friedreich ataxia, and dyslexia. The American Academy of Audiology (AAA) published suggested procedures, but these guidelines do not cite research evidence to support the validity of the recommended procedures for fitting and verifying nonoccluding open-ear FM systems on children with normal hearing. Documenting the validity of these fitting procedures is critical to maximize the potential FM-system benefit in the above-mentioned populations of children with normal hearing and those with auditory-listening problems. The primary goal of this investigation was to determine the validity of the AAA real-ear approach to fitting FM systems on children with normal hearing. The secondary goal of this study was to examine speech-recognition performance in noise and loudness ratings without and with FM systems in children with normal hearing sensitivity. A two-group, cross-sectional design was used in the present study. Twenty-six typically functioning children, ages 5-12 yr, with normal hearing sensitivity participated in the study. Participants used a nonoccluding open-ear FM receiver during laboratory-based testing. Participants completed three laboratory tests: (1) real-ear measures, (2) speech recognition performance in noise, and (3) loudness ratings. Four real-ear measures were conducted to (1) verify that measured output met prescribed-gain targets across the 1000-4000 Hz frequency range for speech stimuli, (2) confirm that the FM-receiver volume did not exceed predicted uncomfortable loudness levels, and (3 and 4) measure changes to the real-ear unaided response when placing the FM receiver in the child's ear. After completion of the fitting, speech recognition in noise at a -5

The role of insulin-like growth factor-I in the physiopathology of hearing

Full Text Available Insulin like growth factor I (IGF-I belongs to the family of polypeptides of insulin, which play a central role in embryonic development and adult nervous system homeostasis by endocrine, autocrine and paracrine mechanisms. IGF-I is fundamental for the regulation of cochlear development, growth and differentiation, and its mutations are associated with hearing loss in mice and men. Low levels of IGF-I have been shown to correlate with different human syndromes showing hearing loss and with presbyacusis. Animal models are fundamental to understand the genetic, epigenetic, and environmental factors that contribute to human hearing loss. In the mouse, IGF-I serum levels decrease with ageing and there is a concomitant hearing loss and retinal degeneration. In the Igf1-/- null mouse, hearing loss is due to neuronal loss, poor innervation of the sensory hair cells and age-related stria vascularis alterations. In the inner ear, IGF-I actions are mediated by intracellular signaling networks, RAF, AKT and p38 MAPK protein kinases modulate the expression and activity of transcription factors, as AP1, MEF2, FoxM1 and FoxP3, leading to the regulation of cell cycle and metabolism. Therapy with rhIGF-I has been approved in humans for the treatment of poor linear growth and certain neurodegenerative diseases. This review will discuss these findings and their implications in new IGF-I-based treatments for the protection or repair of hearing loss.

Hearing impairment caused by noise, traditionally called - depending on the duration of exposure - acute or chronic acoustic trauma, includes, in addition to presbyacusis, the most common adult population of hearing impaired. In Poland - according to the report of the Central Statistical Office (GUS, 2011), the number of workers employed in NDN exceeded the noise level (85 dB) is about 200 thousand, the highest in the mining, metal and metal products production, textiles and wood production. According to the Regulation of the Council of Ministers of on June 30, 2009, on the list of occupational diseases (Journal of Laws No. 132, item 1115), it is defined as "bilateral permanent hearing loss of the cochlear or sensory-nerve type, expressed as an increase in hearing threshold of at least 45 dB in the ear better heard, calculated as an arithmetic mean for frequencies 1,2 and 3 kHz. Hearing impairments also occur in the military and police during field training and in combat where the source of acoustic injuries are firearms and pulse-inducing explosions (as in some industries) with high C peak levels (Lc peak) Time to rise to a maximum of <1 ms. The prevalence of loud music listening, particularly by personal stereo players, is also affecting children and adolescents with audiometric hearing loss, according to the World Health Organization (WHO) estimates of around 15-20%. The preventive action strategy is defined by the European Union legislation and the national implementing legislation that reduces or eliminates the risk and reduces (if not eliminated), taking into account available technical and organizational solutions to minimize the risk of hearing damage. If you can not reduce the noise levels with technical and organizational methods, you need individual hearing protectors. Ear protectors may be equipped with electronic systems with active noise reduction (which can improve low and medium frequency performance), adjustable attenuation (improves speech

Despite recent technological advances in diagnostic methods including imaging technology, it is often difficult to establish a preoperative diagnosis of conductive hearing loss (CHL) in patients with an intact tympanic membrane (TM). Especially, in patients with a normal temporal bone computed tomography (TBCT), preoperative diagnosis is more difficult. We investigated middle ear disorders encountered in patients with CHL involving an intact TM and normal TBCT. We also analyzed the surgical results with special reference to the pathology. We reviewed the medical records of 365 patients with intact TM, who underwent exploratory tympanotomy for CHL. Fifty nine patients (67 ears, eight bilateral surgeries) had a normal preoperative TBCT findings reported by neuro-radiologists. Demographic data, otologic history, TM findings, preoperative imaging findings, intraoperative findings, and pre- and postoperative audiologic data were obtained and analyzed. Exploration was performed most frequently in the second and fifth decades. The most common postoperative diagnosis was stapedial fixation with non-progressive hearing loss. The most commonly performed hearing-restoring procedure was stapedotomy with piston wire prosthesis insertion. Various types of hearing-restoring procedures during exploration resulted in effective hearing improvement, especially with better outcome in the ossicular chain fixation group. In patients with CHL who have intact TM and normal TBCT, we should consider an exploratory tympanotomy for exact diagnosis and hearing improvement. Information of the common operative findings from this study may help in preoperative counseling.

An important aspect of binaural hearing is the proper detection of interaural sound level differences and interaural timing differences. Assessments of binaural hearing were made in patients with acquired unilateral conductive hearing loss (UCHL, n = 11) or congenital UCHL (n = 10) after unilateral application of a bone conduction device (BCD), and in patients with bilateral conductive or mixed hearing loss after bilateral BCD application. Benefit (bilateral versus unilateral listening) was assessed by measuring directional hearing, compensation of the acoustic head shadow, binaural summation and binaural squelch. Measurements were performed after an acclimatization time of at least 10 weeks. Unilateral BCD application was beneficial, but there was less benefit in the patients with congenital UCHL as compared to patients with acquired UCHL. In adults with bilateral hearing loss, bilateral BCD application was clearly beneficial as compared to unilateral BCD application. Binaural summation was present, but binaural squelch could not be proven. To explain the poor results in the patients with congenital UCHL, two factors seemed to be important. First, a critical period in the development of binaural hearing might affect the binaural hearing abilities. Second, crossover stimulation, referring to additional stimulation of the cochlea contralateral to the BCD side, might deteriorate binaural hearing in patients with UCHL. Copyright © 2011 S.

Hearing screening is important for the early detection of hearing loss. The requirements of specialized equipment, skilled personnel, and quiet environments for valid screening results limit its application in schools and health clinics. This study aimed to develop an automated hearing screening kit (auto-kit) with the capability of realtime noise level monitoring to ensure that the screening is performed in an environment that conforms to the standard. The auto-kit consists of a laptop, a 24-bit resolution sound card, headphones, a microphone, and a graphical user interface, which is calibrated according to the American National Standards Institute S3.6-2004 standard. The auto-kit can present four test tones (500, 1000, 2000, and 4000 Hz) at 25 or 40 dB HL screening cut-off level. The clinical results at 40 dB HL screening cut-off level showed that the auto-kit has a sensitivity of 92.5% and a specificity of 75.0%. Because the 500 Hz test tone is not included in the standard hearing screening procedure, it can be excluded from the auto-kit test procedure. The exclusion of 500 Hz test tone improved the specificity of the auto-kit from 75.0% to 92.3%, which suggests that the auto-kit could be a valid hearing screening device. In conclusion, the auto-kit may be a valuable hearing screening tool, especially in countries where resources are limited.

Hearing in young adults. Part I: The effects of attitudes and beliefs toward noise, hearing loss, and hearing protector devices

Full Text Available There is great concern regarding the development of noise-induced hearing loss (NIHL in youth caused by high sound levels during various leisure activities. Health-orientated behavior of young adults might be linked to the beliefs and attitudes toward noise, hearing loss, and hearing protector devices (HPDs. The objective of the current study was to evaluate the effects of attitudes and beliefs toward noise, hearing loss, and HPDs on young adults′ hearing status. A questionnaire and an audiological test battery were completed by 163 subjects (aged 18-30 years. The questionnaire contained the Youth Attitude to Noise Scale (YANS and Beliefs about Hearing Protection and Hearing Loss (BAHPHL. A more positive attitude or belief represented an attitude where noise or hearing loss is seen as unproblematic and attitudes and beliefs regarding HPDs is worse. Hearing was evaluated using (high frequency pure tone audiometry (PTA, transient evoked and distortion product otoacoustic emissions. First, mean differences in hearing between the groups with different attitudes and beliefs were evaluated using one-way analysis of variance (ANOVA. Second, a χ2 test was used to examine the usage of HPDs by the different groups with different attitudes and beliefs. Young adults with a positive attitude had significantly more deteriorated hearing and used HPDs less than the other subjects. Hearing conservation programs (HCPs for young adults should provide information and knowledge regarding noise, hearing loss, and HPDs. Barriers wearing HPDs should especially be discussed. Further, those campaigns should focus on self-experienced hearing related symptoms that might serve as triggers for attitudinal and behavioral changes.

The present study investigates the hemispheric contributions of neuronal reorganization following early single-sided hearing (unilateral deafness). The experiments were performed on ten cats from our colony of deaf white cats. Two were identified in early hearing screening as unilaterally congenitally deaf. The remaining eight were bilaterally congenitally deaf, unilaterally implanted at different ages with a cochlear implant. Implanted animals were chronically stimulated using a single-channel portable signal processor for two to five months. Microelectrode recordings were performed at the primary auditory cortex under stimulation at the hearing and deaf ear with bilateral cochlear implants. Local field potentials (LFPs) were compared at the cortex ipsilateral and contralateral to the hearing ear. The focus of the study was on the morphology and the onset latency of the LFPs. With respect to morphology of LFPs, pronounced hemisphere-specific effects were observed. Morphology of amplitude-normalized LFPs for stimulation of the deaf and the hearing ear was similar for responses recorded at the same hemisphere. However, when comparisons were performed between the hemispheres, the morphology was more dissimilar even though the same ear was stimulated. This demonstrates hemispheric specificity of some cortical adaptations irrespective of the ear stimulated. The results suggest a specific adaptation process at the hemisphere ipsilateral to the hearing ear, involving specific (down-regulated inhibitory) mechanisms not found in the contralateral hemisphere. Finally, onset latencies revealed that the sensitive period for the cortex ipsilateral to the hearing ear is shorter than that for the contralateral cortex. Unilateral hearing experience leads to a functionally-asymmetric brain with different neuronal reorganizations and different sensitive periods involved.

An “Uncrimped” SMart Stapes Prosthesis: A Cause of Late Hearing Deterioration in Otosclerosis

Directory of Open Access Journals (Sweden)

Premjit S. Randhawa

2012-01-01

Full Text Available Statement of Problem. Stapedotomy is the treatment of choice for otosclerosis. Numerous techniques and prosthesis are available to perform this procedure. Success rates of surgery vary from 17% to 80%, and revision surgery carries an increased risk of complications as well as poorer hearing outcomes. Method of Study. Case report. Results. We report the first case of uncrimping of a SMart stapes prosthesis with no lateral displacement as a cause of late failure despite successful crimping and improvement in audiological outcomes after initial surgery. Conclusion. The SMart stapes prosthesis is widely used and has been shown to be safe and provide good hearing outcomes. Displacement of a stapes prosthesis is the commonest cause of failure. Our case shows that deterioration of hearing thresholds can occur from uncrimping of the prosthesis with no displacement. It is important to improve our understanding of stapedotomy failure as revision procedures are associated with poorer outcomes.

Possibilities of spatial hearing testing in occupational medicine

Full Text Available Dysfunctions of the organ of hearing are a significant limitation in the performance of occupations that require its full efficiency (vehicle driving, army, police, fire brigades, mining. Hearing impairment is associated with poorer understanding of speech and disturbed sound localization that directly affects the worker’s orientation in space and his/her assessment of distance and location of other workers or, even most importantly, of dangerous machines. Testing sound location abilities is not a standard procedure, even in highly specialized audiological examining rooms. It should be pointed out that the ability to localize sounds which are particularly loud, is not directly associated with the condition of the hearing organ, but is rather considered an auditory function of a higher level. Disturbances in sound localization are mainly associated with structural and functional disturbances of the central nervous system and occur also in patients with normal hearing when tested with standard methods. The article presents different theories explaining the phenomenon of sound localization, such as interaural differences in time, interaural differences in sound intensity, monaural spectrum shape and the anatomical and physiological basis of these processes. It also describes methods of measurement of disturbances in sound localization which are used in Poland and around the world, also by the author of this work. The author analyzed accessible reports on sound localization testing in occupational medicine and the possibilities of using such tests in various occupations requiring full fitness of the organ of hearing.

The effects of hearing impairment on the perception of binaural-pitch stimuli were investigated. Several experiments were performed with normal-hearing and hearing-impaired listeners, including detection and discrimination of binaural pitch, and melody recognition using different types of binaural...... pitches. For the normal-hearing listeners, all types of binaural pitches could be perceived immediately and were musical. The hearing-impaired listeners could be divided into three groups based on their results: (a) some perceived all types of binaural pitches, but with decreased salience or musicality...... compared to normal-hearing listeners; (b) some could only perceive the strongest pitch types; (c) some were unable to perceive any binaural pitch at all. The performance of the listeners was not correlated with audibility. Additional experiments investigated the correlation between performance in binaural...

Lungfish Hearing

Recent research has shown that tympanic middle ears evolved independently in the major vertebrate groups and represent independent experiments in terrestrial hearing. Furthermore, the tympanic ear emerged quite late – ap - proximately 120 mya after the origin of the tetrapods and approximately 70...... my after the first truly terrestrial tetrapods emerged. One of the major challenges is to understand the transitional stages from tetrapod ancestors to the tympanic tetrapod ear, for example how a non-tympanic ear functions in terrestrial hearing.

A study of the high-frequency hearing thresholds of dentistry professionals

Directory of Open Access Journals (Sweden)

Lopes, Andréa Cintra

2012-01-01

Full Text Available Introduction: In the dentistry practice, dentists are exposed to harmful effects caused by several factors, such as the noise produced by their work instruments. In 1959, the American Dental Association recommended periodical hearing assessments and the use of ear protectors. Aquiring more information regarding dentists', dental nurses', and prosthodontists' hearing abilities is necessary to propose prevention measures and early treatment strategies. Objective: To investigate the auditory thresholds of dentists, dental nurses, and prosthodontists. Method: In this clinical and experimental study, 44 dentists (Group I; GI, 36 dental nurses (Group II; GII, and 28 prosthodontists (Group III; GIII were included, , with a total of 108 professionals. The procedures that were performed included a specific interview, ear canal inspection, conventional and high-frequency threshold audiometry, a speech reception threshold test, and an acoustic impedance test. Results: In the 3 groups that were tested, the comparison between the mean hearing thresholds provided evidence of worsened hearing ability relative to the increase in frequency. For the tritonal mean at 500 to 2,000 Hz and 3,000 to 6,000 Hz, GIII presented the worst thresholds. For the mean of the high frequencies (9,000 and 16,000 Hz, GII presented the worst thresholds. Conclusion: The conventional hearing threshold evaluation did not demonstrate alterations in the 3 groups that were tested; however, the complementary tests such as high-frequency audiometry provided greater efficacy in the early detection of hearing problems, since this population's hearing loss impaired hearing ability at frequencies that are not tested by the conventional tests. Therefore, we emphasize the need of utilizing high-frequency threshold audiometry in the hearing assessment routine in combination with other audiological tests.

The Master Hearing Aid

Science.gov (United States)

Curran, James R.

2013-01-01

As early as the 1930s the term Master Hearing Aid (MHA) described a device used in the fitting of hearing aids. In their original form, the MHA was a desktop system that allowed for simulated or actual adjustment of hearing aid components that resulted in a changed hearing aid response. Over the years the MHA saw many embodiments and contributed to a number of rationales for the fitting of hearing aids. During these same years, the MHA was viewed by many as an inappropriate means of demonstrating hearing aids; the audio quality of the desktop systems was often superior to the hearing aids themselves. These opinions and the evolution of the MHA have molded the modern perception of hearing aids and the techniques used in the fitting of hearing aids. This article reports on a history of the MHA and its influence on the fitting of hearing aids. PMID:23686682

Full Text Available Introduction: Parkinson disease (PD is a degenerating disease with a deceitful character, impairing the central nervous system and causing biological, psychological and social changes. It shows motor signs and symptoms characterized by trembling, postural instability, rigidity and bradykinesia. Objective: To evaluate the central hearing function in PD patients. Method: A descriptive, prospect and transversal study, in which 10 individuals diagnosed of PD named study group (SG and 10 normally hearing individuals named control group (CG were evaluated, age average of 63.8 and (SD 5.96. Both groups went through otorhinolaryngological and ordinary audiological evaluations, and dichotic test of alternate disyllables (SSW. Results: In the quantitative analysis, CG showed 80% normality on competitive right-ear hearing (RC and 60% on the competitive left-ear hearing (LC in comparison with the SG that presented 70% on RC and 40% on LC. In the qualitative analysis, the biggest percentage of errors was evident in the SG in the order effect. The results showed a difficulty in identifying a sound when there is another competitive sound and in the memory ability. Conclusion: A qualitative and quantitative difference was observed in the SSW test between the evaluated groups, although statistical data does not show significant differences. The importance to evaluate the central hearing process is emphasized when contributing to the procedures to be taken at the therapeutic follow-up.

Full Text Available The aim was to describe the outcome of neonatal hearing screening (NHS and audiological diagnosis in neonates in the NICU. The sample was divided into Group I: neonates who underwent NHS in one step and Group II: neonates who underwent a test and retest NHS. NHS procedure was automated auditory brainstem response. NHS was performed in 82.1% of surviving neonates. For GI, referral rate was 18.6% and false-positive was 62.2% (normal hearing in the diagnostic stage. In GII, with retest, referral rate dropped to 4.1% and false-positive to 12.5%. Sensorineural hearing loss was found in 13.2% of infants and conductive in 26.4% of cases. There was one case of auditory neuropathy spectrum (1.9%. Dropout rate in whole process was 21.7% for GI and 24.03% for GII. We concluded that it was not possible to perform universal NHS in the studied sample or, in many cases, to apply it within the first month of life. Retest reduced failure and false-positive rate and did not increase evasion, indicating that it is a recommendable step in NHS programs in the NICU. The incidence of hearing loss was 2.9%, considering sensorineural hearing loss (0.91%, conductive (1.83% and auditory neuropathy spectrum (0.19%.

Viral Causes of Hearing Loss: A Review for Hearing Health Professionals

Science.gov (United States)

Cohen, Brandon E.; Durstenfeld, Anne

2014-01-01

A number of viral infections can cause hearing loss. Hearing loss induced by these viruses can be congenital or acquired, unilateral or bilateral. Certain viral infections can directly damage inner ear structures, others can induce inflammatory responses which then cause this damage, and still others can increase susceptibility or bacterial or fungal infection, leading to hearing loss. Typically, virus-induced hearing loss is sensorineural, although conductive and mixed hearing losses can be seen following infection with certain viruses. Occasionally, recovery of hearing after these infections can occur spontaneously. Most importantly, some of these viral infections can be prevented or treated. For many of these viruses, guidelines for their treatment or prevention have recently been revised. In this review, we outline many of the viruses that cause hearing loss, their epidemiology, course, prevention, and treatment. PMID:25080364

The purpose of this paper was to highlight the importance of cultural influence in understanding hearing-help seeking and hearing-aid uptake. Information on audiological services in different countries and 'theories related to cross-culture' is presented, followed by a general discussion. Twenty-seven relevant literature reviews on hearing impairment, cross-cultural studies, and the health psychology model and others as secondary resources. Despite the adverse consequences of hearing impairment and the significant potential benefits of audiological rehabilitation, only a small number of those with hearing impairment seek professional help and take up appropriate rehabilitation. Therefore, hearing help-seeking and hearing-aid uptake has recently become the hot topic for clinicians and researchers. Previous research has identified many contributing factors for hearing help-seeking with self-reported hearing disability being one of the main factors. Although significant differences in help-seeking and hearing-aid adoption rates have been reported across countries in population studies, limited literature on the influence of cross-cultural factors in this area calls for an immediate need for research. This paper highlights the importance of psychological models and cross-cultural research in the area of hearing help-seeking and hearing-aid uptake, and consequently some directions for future research are proposed.

Full Text Available The purpose of this study was to examine the level of empathy in deaf and hard of hearing (preadolescents compared to normal hearing controls and to define the influence of language and various hearing loss characteristics on the development of empathy.The study group (mean age 11.9 years consisted of 122 deaf and hard of hearing children (52 children with cochlear implants and 70 children with conventional hearing aids and 162 normal hearing children. The two groups were compared using self-reports, a parent-report and observation tasks to rate the children's level of empathy, their attendance to others' emotions, emotion recognition, and supportive behavior.Deaf and hard of hearing children reported lower levels of cognitive empathy and prosocial motivation than normal hearing children, regardless of their type of hearing device. The level of emotion recognition was equal in both groups. During observations, deaf and hard of hearing children showed more attention to the emotion evoking events but less supportive behavior compared to their normal hearing peers. Deaf and hard of hearing children attending mainstream education or using oral language show higher levels of cognitive empathy and prosocial motivation than deaf and hard of hearing children who use sign (supported language or attend special education. However, they are still outperformed by normal hearing children.Deaf and hard of hearing children, especially those in special education, show lower levels of empathy than normal hearing children, which can have consequences for initiating and maintaining relationships.

Directory of Open Access Journals (Sweden)

Adrian Fuente

2013-02-01

Full Text Available OBJECTIVE: To compare hearing performance relating to the peripheral and central auditory system between solvent-exposed and non-exposed workers. METHODS: Forty-eight workers exposed to a mixture of solvents and 48 non-exposed control subjects of matched age, gender and educational level were selected to participate in the study. The evaluation procedures included: pure-tone audiometry (500 - 8,000 Hz, to investigate the peripheral auditory system; the Random Gap Detection test, to assess the central auditory system; and the Amsterdam Inventory for Auditory Disability and Handicap, to investigate subjects' self-reported hearing performance in daily-life activities. A Student t test and analyses of covariance (ANCOVA were computed to determine possible significant differences between solvent-exposed and non-exposed subjects for the hearing level, Random Gap Detection test and Amsterdam Inventory for Auditory Disability and Handicap. Pearson correlations among the three measures were also calculated. RESULTS: Solvent-exposed subjects exhibited significantly poorer hearing thresholds for the right ear than non-exposed subjects. Also, solvent-exposed subjects exhibited poorer results for the Random Gap Detection test and self-reported poorer listening performance than non-exposed subjects. Results of the Amsterdam Inventory for Auditory Disability and Handicap were significantly correlated with the binaural average of subject pure-tone thresholds and Random Gap Detection test performance. CONCLUSIONS: Solvent exposure is associated with poorer hearing performance in daily life activities that relate to the function of the peripheral and central auditory system.

This review discusses three categories of direct-to-consumer hearing devices: 1 personal sound amplification products (PSAPs, 2 direct-mail hearing aids, and 3 over-the-counter (OTC hearing aids.Method: A literature review was conducted using EBSCOhost and included the databases CINAHL, MEDLINE, and PsycINFO. After applying prior agreed inclusion and exclusion criteria, 13 reports were included in the review.Results: Included studies fell into three domains: 1 electroacoustic characteristics, 2 consumer surveys, and 3 outcome evaluations. Electroacoustic characteristics of these devices vary significantly with some meeting the stringent acoustic criteria used for hearing aids, while others producing dangerous output levels (ie, over 120-dB sound pressure level. Low-end (or low-cost devices were typically poor in acoustic quality and did not meet gain levels necessary for most adult and elderly hearing loss patterns (eg, presbycusis, especially in high frequencies. Despite direct-mail hearing aids and PSAPs being associated with lower satisfaction when compared to hearing aids purchased through hearing health care professionals, consumer surveys suggest that 5%–19% of people with hearing loss purchase hearing aids through direct-mail or online. Studies on outcome evaluation suggest positive

Teixeira, Adriane Ribeiro

2009-03-01

Full Text Available Introduction: Presbycusis is a public health problem. Despite its high prevalence, many elders do not have their hearing ability investigated periodically, because they do not have a specific complaint. Objective: To check whether there is a relationship between the complaint and the presence of hearing loss in elder people. Method: Transversal study in elders from a neighborhood in the city of Canoas, Rio Grande do Sul. After the definition of the neighborhood's geographic boundaries, all houses were visited, the older people's addresses were ascertained and the invitations to take part in the research were provided. A questionnaire survey was applied which had a question about hearing loss complaint and air-conducted hearing thresholds were obtained and studied. Out of the 72 identified elders 50 elders agreed to participate, 35 (70% women, and 15 (30% men. Results: It was confirmed that only 12 (24% elders showed a specific complaint of hearing loss, although 33 (66% elders showed slight, moderate, severe and profound hearing losses. Conclusion: Data analysis confirmed there was no relationship between the complaint and the presence of hearing loss in the assessed group, and demonstrated the need to forward the elders for audiological evaluation even without any specific complaint.

2016-11-01

Management of children with unilateral hearing loss is not standardized. The primary goal of this study was to elicit patient- and parent-reported perspectives regarding usage of hearing devices in pediatric UHL and to suggest a basic algorithmic approach to management. Our tertiary care center recruited families of youth ages 5-19 years with unilateral hearing loss from January 2014 through October 2015. Parents of all youths completed a 36-item survey, and some youth ages 11-19 years participated in hour-long interviews. We assessed patterns of hearing device usage among participants, and performed qualitative data analysis to understand factors considered by youths when deciding whether or not to use a hearing device. Survey information was collected for 50 patients. Distribution of hearing loss severity in affected ear was mild 14%, moderate 26%, severe 22%, and profound 38%. The majority of children had sensorineural hearing loss (57%), followed by mixed (32%), and then conductive (11%). 34 children (68%) had tried a hearing device; 20 continued to use the device. Retention rates were similar among children with different degrees of hearing loss: mild 66%, moderate 50%, severe 60%, profound 64%. Sixteen children tried a wireless contralateral routing of signal (CROS) device, and 15 tried a behind-the-ear (BTE) hearing aid. Retention rates for CROS and BTE devices were 69% and 47%, respectively. The most common reason for cessation of use was discomfort, followed by lack of benefit. A majority of children with unilateral hearing loss who tried a hearing device continued to use it, and retention rates were similar across all degrees of hearing loss. These findings suggest that personal hearing devices should be included in management protocols. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Elderly With Different Types of Hearing Loss and Comorbidities: Satisfaction With Hearing Aids

Full Text Available Background Hearing loss is developing when age is rising. Initiation and progression rates of hearing loss vary among different individuals and groups. Objectives The current study aimed to determine satisfaction of the elderly with their hearing aids in different types of hearing loss and comorbidities. Patients and Methods The study was conducted on 40 elderly subjects suffering from hearing loss and using hearing aids. The data collection method included assessment of hearing loss in addition to using a questionnaire to estimate respondents' satisfaction with their hearing aids in daily life. The Persian version of the Satisfaction with Amplification in Daily Life (SADL questionnaire was administered. The data were analyzed using descriptive and inferential statistics by SPSS software version19. Results The mean satisfaction scores of the elderly were 4.83 ± 0.51 and 5.36 ± 0.30 in the sensorineural loss groups. There was no significant difference between different comorbidities. There was a significant difference between satisfaction level of cost and services subscales in the symmetrical styles of hearing loss (P value = 0.04. Conclusions The findings of the study indicated a high satisfaction of the elderly with their hearing aids, considering the type of hearing loss. Despite all the efforts to improve the audiologic services during verification process, the elderly should be consulted specifically in order to fit their hearing aid as well as their expectations from aid.

To explore long-term hearing results, quality of life (QoL), quality of hearing (QoH), work-related stress, tinnitus, and balance problems after idiopathic sudden sensorineural hearing loss (ISSNHL). Cross-sectional study. We reviewed the audiograms of 680 patients with unilateral ISSNHL on average 8 years after the hearing impairment, and then divided the patients into two study groups based on whether their ISSNHL had recovered to normal (pure tone average [PTA] ≤ 30 dB) or not (PTA > 30 dB). The inclusion criteria were a hearing threshold decrease of 30 dB or more in at least three contiguous frequencies occurring within 72 hours in the affected ear and normal hearing in the contralateral ear. Audiograms of 217 patients fulfilled the criteria. We reviewed their medical records; measured present QoL, QoH, and work-related stress with specific questionnaires; and updated the hearing status. Poor hearing outcome after ISSNHL was correlated with age, severity of hearing loss, and vertigo together with ISSNHL. Quality of life and QoH were statistically significantly better in patients with recovered hearing, and the patients had statistically significantly less tinnitus and balance problems. During the 8-year follow-up, the PTA of the affected ear deteriorated on average 7 dB, and healthy ear deteriorated 6 dB. Idiopathic sudden sensorineural hearing loss that failed to recover had a negative impact on long-term QoL and QoH. The hearing deteriorated as a function of age similarly both in the affected and the healthy ear, and there were no differences between the groups. The cumulative recurrence rate for ISSNHL was 3.5%. 4 Laryngoscope, 127:927-931, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

Twenty-two articles that were directly relevant to this topic were included in this review. The evidence suggests that individuals are more likely to seek help for hearing impairment and/or adopt hearing aids if they: (1) have a moderate to severe hearing impairment and self-reported hearing-related activity limitations or participation restrictions; (2) are older; (3) perceive their hearing as poor; (4) consider there to be more benefits than barriers to amplification; and (5) perceive their significant other/s as supportive of hearing rehabilitation. A barrier to help-seeking for hearing impairment and hearing aid adoption appears to be general practitioners' management of age-related hearing impairment.

Hearing is of utmost importance for normal speech and social development. Even children who have mild or unilateral permanent hearing loss may experience difficulties with understanding speech, as well as problems with educational and psycho-social development. The increasing advantages of middle-ear implant technologies are opening new perspectives for restoring hearing. Active middle-ear implants can be used in children and adolescents with hearing loss. In addition to the well-documented results for improving speech intelligibility and quality of hearing in sensorineural hearing loss active middle-ear implants are now successfully used in patients with conductive and mixed hearing loss. In this article we present a case of successful, single-stage vibroplasty, on the right side with the fixation of the FMT on the stapes and PORP CLiP vibroplasty on the left side in a 6-year-old girl with bilateral mixed hearing loss and multiple dyslalia associated with Franceschetti syndrome (mandibulofacial dysostosis). CT revealed bilateral middle-ear malformations as well as an atretic right and stenotic left external auditory canal. Due to craniofacial dysmorphia airway and (post)operative, management is significantly more difficult in patients with a Franceschetti syndrome which in this case favoured a single-stage bilateral procedure. No intra- or postoperative surgical complications were reported. The middle-ear implants were activated 4 weeks after surgery. In the audiological examination 6 months after surgery, the child showed 100% speech intelligibility with activated implants on each side.

Individual Hearing Loss

Full Text Available It is well-established that hearing loss does not only lead to a reduction of hearing sensitivity. Large individual differences are typically observed among listeners with hearing impairment in a wide range of suprathreshold auditory measures. In many cases, audiometric thresholds cannot fully account for such individual differences, which make it challenging to find adequate compensation strategies in hearing devices. How to characterize, model, and compensate for individual hearing loss were the main topics of the fifth International Symposium on Auditory and Audiological Research (ISAAR, held in Nyborg, Denmark, in August 2015. The following collection of papers results from some of the work that was presented and discussed at the symposium.

Arnold, P; Murray, C

1998-07-01

The memory of 11 deaf and 11 hearing British Sign Language users and 11 hearing nonsigners for pictures of faces of and verbalizable objects was measured using the game Concentration. The three groups performed at the same level for the objects. In contrast the deaf signers were better for faces than the hearing signers, who in turn were superior to the hearing nonsigners, who were the worst. Three hypotheses were made: That there would be no significant difference in terms of the number of attempts between the three groups on the verbalizable object task, that the hearing and deaf signers would demonstrate superior performance to that of the hearing nonsigners on the matching faces task, and that the hearing and deaf signers would exhibit similar performance levels on the matching faces task. The first two hypotheses were supported, but the third was not. Deaf signers were found to be superior for memory for faces to hearing signers and hearing nonsigners. Possible explanations for the findings are discussed, including the possibility that deafness and the long use of sign language have additive effects.

Our findings show that it’s necessary to provide psychological and social support for mothers of hearing-impaired children.

Spatial Release From Masking in Children: Effects of Simulated Unilateral Hearing Loss.

Science.gov (United States)

Corbin, Nicole E; Buss, Emily; Leibold, Lori J

The purpose of this study was twofold: (1) to determine the effect of an acute simulated unilateral hearing loss on children's spatial release from masking in two-talker speech and speech-shaped noise, and (2) to develop a procedure to be used in future studies that will assess spatial release from masking in children who have permanent unilateral hearing loss. There were three main predictions. First, spatial release from masking was expected to be larger in two-talker speech than in speech-shaped noise. Second, simulated unilateral hearing loss was expected to worsen performance in all listening conditions, but particularly in the spatially separated two-talker speech masker. Third, spatial release from masking was expected to be smaller for children than for adults in the two-talker masker. Participants were 12 children (8.7 to 10.9 years) and 11 adults (18.5 to 30.4 years) with normal bilateral hearing. Thresholds for 50%-correct recognition of Bamford-Kowal-Bench sentences were measured adaptively in continuous two-talker speech or speech-shaped noise. Target sentences were always presented from a loudspeaker at 0° azimuth. The masker stimulus was either co-located with the target or spatially separated to +90° or -90° azimuth. Spatial release from masking was quantified as the difference between thresholds obtained when the target and masker were co-located and thresholds obtained when the masker was presented from +90° or -90° azimuth. Testing was completed both with and without a moderate simulated unilateral hearing loss, created with a foam earplug and supra-aural earmuff. A repeated-measures design was used to compare performance between children and adults, and performance in the no-plug and simulated-unilateral-hearing-loss conditions. All listeners benefited from spatial separation of target and masker stimuli on the azimuth plane in the no-plug listening conditions; this benefit was larger in two-talker speech than in speech-shaped noise. In the

The purpose of this study was to examine the level of empathy in deaf and hard of hearing (pre)adolescents compared to normal hearing controls and to define the influence of language and various hearing loss characteristics on the development of empathy. The study group (mean age 11.9 years) consisted of 122 deaf and hard of hearing children (52 children with cochlear implants and 70 children with conventional hearing aids) and 162 normal hearing children. The two groups were compared using self-reports, a parent-report and observation tasks to rate the children's level of empathy, their attendance to others' emotions, emotion recognition, and supportive behavior. Deaf and hard of hearing children reported lower levels of cognitive empathy and prosocial motivation than normal hearing children, regardless of their type of hearing device. The level of emotion recognition was equal in both groups. During observations, deaf and hard of hearing children showed more attention to the emotion evoking events but less supportive behavior compared to their normal hearing peers. Deaf and hard of hearing children attending mainstream education or using oral language show higher levels of cognitive empathy and prosocial motivation than deaf and hard of hearing children who use sign (supported) language or attend special education. However, they are still outperformed by normal hearing children. Deaf and hard of hearing children, especially those in special education, show lower levels of empathy than normal hearing children, which can have consequences for initiating and maintaining relationships.

[Presbycusis - Age Related Hearing Loss].

Fischer, N; Weber, B; Riechelmann, H

2016-07-01

Presbycusis or age related hearing loss can be defined as a progressive, bilateral and symmetrical sensorineural hearing loss due to age related degeneration of inner ear structures. It can be considered a multifactorial complex disorder with environmental and genetic factors. The molecular, electrophysiological and histological damage at different levels of the inner ear cause a progressive hearing loss, which usually affects the high frequencies of hearing. The resulting poor speech recognition has a negative impact on cognitive, emotional and social function in older adults. Recent investigations revealed an association between hearing impairment and social isolation, anxiety, depression and cognitive decline in elderly. These findings emphasize the importance of diagnosis and treating hearing loss in the elderly population. Hearing aids are the most commonly used devices for treating presbycusis. The technical progress of implantable hearing devices allows an effective hearing rehabilitation even in elderly with severe hearing loss. However, most people with hearing impairments are not treated adequately. © Georg Thieme Verlag KG Stuttgart · New York.

More than 90% of newborns in the United States are now being screened for hearing loss. A large fraction of cases of unilateral hearing loss and mild bilateral hearing loss are not currently identified through newborn hearing screening. This is of concern because a preponderance of research has demonstrated that unilateral hearing loss and mild bilateral hearing loss can lead to developmental delays and educational problems for some children. To help address this probable underidentification ...

The use of problem-solving strategies by 59 deaf and hard of hearing children, grades K-3, was investigated. The children were asked to solve 9 arithmetic story problems presented to them in American Sign Language. The researchers found that while the children used the same general types of strategies that are used by hearing children (i.e., modeling, counting, and fact-based strategies), they showed an overwhelming use of counting strategies for all types of problems and at all ages. This difference may have its roots in language or instruction (or in both), and calls attention to the need for conceptual rather than procedural mathematics instruction for deaf and hard of hearing students.

This study examined the language outcomes of children with mild to severe hearing loss during the preschool years. The longitudinal design was leveraged to test whether language growth trajectories were associated with degree of hearing loss and whether aided hearing influenced language growth in a systematic manner. The study also explored the influence of the timing of hearing aid fitting and extent of use on children's language growth. Finally, the study tested the hypothesis that morphosyntax may be at particular risk due to the demands it places on the processing of fine details in the linguistic input. The full cohort of children in this study comprised 290 children who were hard of hearing (CHH) and 112 children with normal hearing who participated in the Outcomes of Children with Hearing Loss (OCHL) study between the ages of 2 and 6 years. CHH had a mean better-ear pure-tone average of 47.66 dB HL (SD = 13.35). All children received a comprehensive battery of language measures at annual intervals, including standardized tests, parent-report measures, and spontaneous and elicited language samples. Principal components analysis supported the use of a single composite language score for each of the age levels (2, 3, 4, 5, and 6 years). Measures of unaided (better-ear pure-tone average, speech intelligibility index) and aided (residualized speech intelligibility index) hearing were collected, along with parent-report measures of daily hearing aid use time. Mixed modeling procedures were applied to examine the rate of change (227 CHH; 94 children with normal hearing) in language ability over time in relation to (1) degree of hearing loss, (2) aided hearing, (3) age of hearing aid fit and duration of use, and (4) daily hearing aid use. Principal components analysis was also employed to examine factor loadings from spontaneous language samples and to test their correspondence with standardized measures. Multiple regression analysis was used to test for

The signal processing and fitting methods used for hearing aids have mainly been designed to optimize the intelligibility of speech. Little attention has been paid to the effectiveness of hearing aids for listening to music. Perhaps as a consequence, many hearing-aid users complain that they are not satisfied with their hearing aids when listening to music. This issue inspired the Internet-based survey presented here. The survey was designed to identify the nature and prevalence of problems associated with listening to live and reproduced music with hearing aids. Responses from 523 hearing-aid users to 21 multiple-choice questions are presented and analyzed, and the relationships between responses to questions regarding music and questions concerned with information about the respondents, their hearing aids, and their hearing loss are described. Large proportions of the respondents reported that they found their hearing aids to be helpful for listening to both live and reproduced music, although less so for the former. The survey also identified problems such as distortion, acoustic feedback, insufficient or excessive gain, unbalanced frequency response, and reduced tone quality. The results indicate that the enjoyment of listening to music with hearing aids could be improved by an increase of the input and output dynamic range, extension of the low-frequency response, and improvement of feedback cancellation and automatic gain control systems. © The Author(s) 2014.

Objective Options for management of unilateral hearing loss (UHL) in children include conventional hearing aids, bone-conduction hearing devices, contralateral routing of signal (CROS) aids, and frequency-modulating (FM) systems. The objective of this study was to systematically review the current literature to characterize auditory outcomes of hearing rehabilitation options in UHL. Data Sources PubMed, EMBASE, Medline, CINAHL, and Cochrane Library were searched from inception to January 2016. Manual searches of bibliographies were also performed. Review Methods Studies analyzing auditory outcomes of hearing amplification in children with UHL were included. Outcome measures included functional and objective auditory results. Two independent reviewers evaluated each abstract and article. Results Of the 249 articles identified, 12 met inclusion criteria. Seven articles solely focused on outcomes with bone-conduction hearing devices. Outcomes favored improved pure-tone averages, speech recognition thresholds, and sound localization in implanted patients. Five studies focused on FM systems, conventional hearing aids, or CROS hearing aids. Limited data are available but suggest a trend toward improvement in speech perception with hearing aids. FM systems were shown to have the most benefit for speech recognition in noise. Studies evaluating CROS hearing aids demonstrated variable outcomes. Conclusions Data evaluating functional and objective auditory measures following hearing amplification in children with UHL are limited. Most studies do suggest improvement in speech perception, speech recognition in noise, and sound localization with a hearing rehabilitation device.

Vogel, Ineke; Brug, Johannes; Hosli, Esther J; van der Ploeg, Catharina P B; Raat, Hein

2008-03-01

To explore adolescents' behaviors and opinions about exposure to loud music from MP3 players. We conducted a qualitative analysis of focus-group discussions with adolescents aged 12 to 18 years from 2 large secondary schools (1 urban and 1 rural) for pre-vocational and pre-university education. The semi-structured question route was theoretically framed within the protection motivation theory. Most adolescents-especially male students and students from pre-vocational schools-indicated that they often played their MP3 players at maximum volume. Although they appeared to be generally aware of the risks of exposure to loud music, they expressed low personal vulnerability to music-induced hearing loss. Most adolescents said that they would not accept any interference with their music-exposure habits. Interventions should target students from pre-vocational schools and should focus on increasing adolescents' knowledge of the risks of loud music and how to protect themselves. Besides hearing education for adolescents and technical modifications of MP3 players, volume-level regulations for MP3 players may be warranted.

Applications of direct-to-consumer hearing devices for adults with hearing loss: a review

Manchaiah, Vinaya; Taylor, Brian; Dockens, Ashley L; Tran, Nicole R; Lane, Kayla; Castle, Mariana; Grover, Vibhu

2017-01-01

Background This systematic literature review is aimed at investigating applications of direct-to-consumer hearing devices for adults with hearing loss. This review discusses three categories of direct-to-consumer hearing devices: 1) personal sound amplification products (PSAPs), 2) direct-mail hearing aids, and 3) over-the-counter (OTC) hearing aids. Method A literature review was conducted using EBSCOhost and included the databases CINAHL, MEDLINE, and PsycINFO. After applying prior agreed inclusion and exclusion criteria, 13 reports were included in the review. Results Included studies fell into three domains: 1) electroacoustic characteristics, 2) consumer surveys, and 3) outcome evaluations. Electroacoustic characteristics of these devices vary significantly with some meeting the stringent acoustic criteria used for hearing aids, while others producing dangerous output levels (ie, over 120-dB sound pressure level). Low-end (or low-cost) devices were typically poor in acoustic quality and did not meet gain levels necessary for most adult and elderly hearing loss patterns (eg, presbycusis), especially in high frequencies. Despite direct-mail hearing aids and PSAPs being associated with lower satisfaction when compared to hearing aids purchased through hearing health care professionals, consumer surveys suggest that 5%–19% of people with hearing loss purchase hearing aids through direct-mail or online. Studies on outcome evaluation suggest positive outcomes of OTC devices in the elderly population. Of note, OTC outcomes appear better when a hearing health care professional supports these users. Conclusion While some direct-to-consumer hearing devices have the capability to produce adverse effects due to production of dangerously high sound levels and internal noise, the existing literature suggests that there are potential benefits of these devices. Research of direct-to-consumer hearing devices is limited, and current published studies are of weak quality. Much

Oral communication and auditory skills of hearing impaired children and adolescents and the speech therapy rehabilitation process

Directory of Open Access Journals (Sweden)

Rafaela da Silva Bicas

Full Text Available ABSTRACT Purpose: to analyze auditory and oral communication behaviors in a group of children and adolescents, users of cochlear implants and to establish a relationship with factors that interfere with aural rehabilitation. Methods: participants were 13 children or adolescents with profound bilateral sensorineural hearing loss. Standardized procedures were applied to check: the auditory and oral communication behaviors of participants and their relationships with the child's age at diagnosis period; the interval between diagnosis and intervention, adaptation onset of the cochlear implant; the hearing age and aural rehabilitation period. Results: statistically significant data were found to correlate the interval between diagnosis and intervention with the scores in the evaluation procedures of oral communication. Conclusion: there was a significant impact on the development of oral communication when the period elapsed between the diagnosis and intervention was analyzed, in such way that the faster the intervention time, the better the results. It was also evident that the earlier the beginning of the use of cochlear implants, the greater the hearing age, and the longer the rehabilitation period, the better the scores in the procedures that evaluated auditory and verbal development.

This study aimed to create a multiple regression model for predicting hearing outcomes of idiopathic sudden sensorineural hearing loss (ISSNHL). The participants were 205 consecutive patients (205 ears) with ISSNHL (hearing level ≥ 40 dB, interval between onset and treatment ≤ 30 days). They received systemic steroid administration combined with intratympanic steroid injection. Data were examined by simple and multiple regression analyses. Three hearing indices (percentage hearing improvement, hearing gain, and posttreatment hearing level [HLpost]) and 7 prognostic factors (age, days from onset to treatment, initial hearing level, initial hearing level at low frequencies, initial hearing level at high frequencies, presence of vertigo, and contralateral hearing level) were included in the multiple regression analysis as dependent and explanatory variables, respectively. In the simple regression analysis, the percentage hearing improvement, hearing gain, and HLpost showed significant correlation with 2, 5, and 6 of the 7 prognostic factors, respectively. The multiple correlation coefficients were 0.396, 0.503, and 0.714 for the percentage hearing improvement, hearing gain, and HLpost, respectively. Predicted values of HLpost calculated by the multiple regression equation were reliable with 70% probability with a 40-dB-width prediction interval. Prediction of HLpost by the multiple regression model may be useful to estimate the hearing prognosis of ISSNHL. © The Author(s) 2014.

Children with sensorineural hearing loss can present with instabilities in postural control, possibly as a consequence of hypoactivity of their vestibular system due to internal ear injury. To assess postural control stability in students with normal hearing (i.e., listeners) and with sensorineural hearing loss, and to compare data between groups, considering gender and age. This cross-sectional study evaluated the postural control of 96 students, 48 listeners and 48 with sensorineural hearing loss, aged between 7 and 18 years, of both genders, through the Balance Error Scoring Systems scale. This tool assesses postural control in two sensory conditions: stable surface and unstable surface. For statistical data analysis between groups, the Wilcoxon test for paired samples was used. Students with hearing loss showed more instability in postural control than those with normal hearing, with significant differences between groups (stable surface, unstable surface) (ppostural control compared to normal hearing students of the same gender and age.

The public hearing is an integral part of the licensing procedure under the German Atomic Energy Act Section 7 of this Act provides that construction and operation of stationary installations for the production or fission of nuclear fuel, or for the reprocessing of irradiated nuclear fuel, shall be subject to the grant of a licence. The relevant licensing procedure according to Section 7 is laid down in the German Nuclear Installations Ordinance. This Ordinance provides in Section 2, Paragraph 1: 'As soon as the documents (i.e. those required for examination) are complete, the licensing authority shall notify the public of the project in its official gazette and in a daily newspaper which is read in the region of the site of the installation. Reference to this notice shall be made in the German Federal Register'. Paragraph 2 continues: 'The notice shall (1) state that the application for granting a licence or a preliminary licence has been made and where the documents... (required for examination)... are available for inspection by the public; (2) invite the public to file objections, if any, with a board to be specified in said notice within thirty days after the day following the publication of said official gazette; (3) fix the date of a public hearing and point out that the objections raised will be discussed during said hearing independent of whether the applicant or the persons who have filed objections will appear or fail to appear.'

Full Text Available Background and Aim: Hearing loss is one of the most prevalent chronic diseases in the elderly; using a hearing aid to alleviate auditory impairment can positively affect their quality of life. This research aimed to determine the level of satisfaction concerning hearing aids in elderly people with hearing impairment based on the type and degree of hearing loss.Methods: An analytic cross-sectional research design was used ; the sample included 40 elderly people who used hearing aids. According to the World Health Organization (WHO age classification, participants were divided into two age groups: 65-74 years (n=20 and 75-90 years (n=20. Satisfaction levels were assessed using a standard satisfaction with amplification in daily life (SADL questionnaire.Results: Satisfaction levels in the 65-74 age group were significantly higher than that in the 75-90 age group (p=0.02. Participants with mixed hearing loss revealed higher satisfaction levels than participants with sensorineural hearing loss (p=0.02. On the negative effects dimension, participants with severe hearing loss exhibited significantly higher satisfaction levels than participants with moderate or moderate to severe hearing loss (p=0.01.Conclusion: Total satisfaction mean scores were relatively high in the elderly participants . Negative features could be reduced via careful consultation regarding the aids’ amplifying capabilities and limitations in groups with moderate or moderate to severe hearing loss.

Background Hearing loss is a potential late effect after childhood cancer. Questionnaires are often used to assess hearing in large cohorts of childhood cancer survivors and it is important to know if they can provide valid measures of hearing loss. We therefore assessed agreement and validity of questionnaire-reported hearing in childhood cancer survivors using medical records as reference. Procedure In this validation study, we studied 361 survivors of childhood cancer from the Swiss Childhood Cancer Survivor Study (SCCSS) who had been diagnosed after 1989 and had been exposed to ototoxic cancer treatment. Questionnaire-reported hearing was compared to the information in medical records. Hearing loss was defined as ≥ grade 1 according to the SIOP Boston Ototoxicity Scale. We assessed agreement and validity of questionnaire-reported hearing overall and stratified by questionnaire respondents (survivor or parent), sociodemographic characteristics, time between follow-up and questionnaire and severity of hearing loss. Results Questionnaire reports agreed with medical records in 85% of respondents (kappa 0.62), normal hearing was correctly assessed in 92% of those with normal hearing (n = 249), and hearing loss was correctly assessed in 69% of those with hearing loss (n = 112). Sensitivity of the questionnaires was 92%, 74%, and 39% for assessment of severe, moderate and mild bilateral hearing loss; and 50%, 33% and 10% for severe, moderate and mild unilateral hearing loss, respectively. Results did not differ by sociodemographic characteristics of the respondents, and survivor- and parent-reports were equally valid. Conclusions Questionnaires are a useful tool to assess hearing in large cohorts of childhood cancer survivors, but underestimate mild and unilateral hearing loss. Further research should investigate whether the addition of questions with higher sensitivity for mild degrees of hearing loss could improve the results. PMID:28333999

Pre-enlistment hearing loss and hearing loss disability among US soldiers and marines

Directory of Open Access Journals (Sweden)

Marlene E Gubata

2013-01-01

Full Text Available Hearing loss is a common condition among US adults, with some evidence of increasing prevalence in young adults. Noise-induced hearing loss attributable to employment is a significant source of preventable morbidity world-wide. The US military population is largely comprised of young adult males serving in a wide variety of occupations, many in high noise-level conditions, at least episodically. To identify accession and service-related risk factors for hearing-related disability, matched case-control study of US military personnel was conducted. Individuals evaluated for hearing loss disability in the US Army and Marine Corps were frequency matched to controls without history of disability evaluation on service and enlistment year. Conditional logistic regression was used to examine the association between accession and service-related factors and hearing-related disability evaluations between October 2002 and September 2010. Individuals with medically disqualifying audiograms or hearing loss diagnoses at application for military service were 8 and 4 times more likely, respectively, to have a disability evaluation related to hearing loss, after controlling for relevant accession, demographic, and service-related factors. Conservative hearing loss thresholds on pre-enlistment audiograms, stricter hearing loss medical waiver policies or qualified baseline audiograms pre-enlistment are needed in the U.S military. Industrial corporations or labor unions may also benefit from identifying individuals with moderate hearing loss at the time of employment to ensure use of personal protective equipment and engineer controls of noise.

The worker's ear: a history of noise-induced hearing loss.

Science.gov (United States)

Thurston, Floyd E

2013-03-01

Hearing loss afflicts millions of people throughout the world, and many of those millions are workers who have been exposed to excessive noise. People have always been surrounded by a variety of sounds in their environments, but the invention of gunpowder and the Industrial Revolution introduced new sounds of greater intensity than ever before. It is only within the past 40 years that serious efforts to reduce excessive noise at work sites have been initiated. In the latter half of the 20th century, many governments imposed regulations to limit workers' exposure to loud sounds. Because of this recent action, some people may believe that the recognition of occupational noise-induced hearing loss (NIHL) is relatively new. However, a review of selected historical and medical manuscripts, books, and articles show that the association of hearing changes with loud noise exposure was recognized for centuries before systematic attempts were made to limit the exposure. Delays in implementing controls to limit noise exposure were due to cultural reasons, technical problems in controlling noise generation, and a lack of understanding of the mechanics of hearing loss. A historical perspective on this issue may remind health care providers that they need to continue to emphasize hearing conservation measures as occupational noise exposures change with the shift of industrial activities between countries.

1986-01-01

Representatives of the waste disposal industry, environmental agencies and organizations, and nuclear medicine were among the nine witnesses at a hearing held to discuss S. 892, which clarifies the Environmental Protection Agency (EPA) responsibility for radioactive materials mixed with solid wastes. The witnesses responded to questions about procedures at commercial waste sites to protect public health and safety and about the long-term potential of alternatives to land disposal. At issue were the overlapping jurisdictions of EPA and the Nuclear Regulatory Commission and the validity of traditional self-management in the waste area. Witnesses described how nuclear medicine and other depends upon one disposal site, and their concern that regulations permit the states to proceed with site planning to handle these wastes. The text of S. 892 and additional statements submitted for the record follow the testimony

Cochlear implantation: is hearing preservation necessary in severe to profound hearing loss?

Science.gov (United States)

Derinsu, Ufuk; Serin, Gediz Murat; Akdaş, Ferda; Batman, Çağlar

2011-03-01

The goal of the cochlear implant surgery is to place the electrode array with minimal damage to preserve the residual hearing. Round-window insertion can be performed in a manner that is potentially less traumatic than the standard cochleostomy. The purpose of the study was to investigate audiological results of the round-window approach using standard electrode. A retrospective study was performed to evaluate our experience in patients with implanted through round window between January 2007 and March 2009. Sixty patients had undergone cochlear implant surgery through the round window with full insertion of a standard electrode array. Preoperative and postoperative pure-tone thresholds were measured for implanted ears in the range of 250 to 4000 Hz. Within these 60 cases, 31 patients had been evaluated. The population comprised 16 women and 15 men. The mean age was 15.96 years (range, 4-64 years). Follow-up times ranged from 6 to 26 months. Preservation of low-frequency hearing (250 and 500 Hz) was achieved in 27 (87%) of 31 patients. Complete hearing preservation (all frequencies) was accomplished in 11 patients (35.48%). No hearing could be determined postoperatively in 4 patients (12.9%), having preoperative thresholds of 120 dB at 250, 500, and 1000 Hz. Round-window approach has been widely used for preservation of residual hearing. In our patients with severe to profound hearing loss, we preserved residual hearing. Although the residual hearing cannot be sufficient for using additional acoustic stimulation, the preserved residual hearing means minimal damage and a more convenient cochlea, so this is promising for future development.

2011-03-15

Hearing impairment is the most common sensory impairment in humans, affecting 1:1,000 births. We have identified an ENU generated mouse mutant, Mozart, with recessively inherited, non-syndromic progressive hearing loss caused by a mutation in the synaptojanin 2 (Synj2), a central regulatory enzyme in the phosphoinositide-signaling cascade. The hearing loss in Mozart is caused by a p.Asn538Lys mutation in the catalytic domain of the inositol polyphosphate 5-phosphatase synaptojanin 2. Within the cochlea, Synj2 mRNA expression was detected in the inner and outer hair cells but not in the spiral ganglion. Synj2(N538K) mutant protein showed loss of lipid phosphatase activity, and was unable to degrade phosphoinositide signaling molecules. Mutant Mozart mice (Synj2(N538K/N538K)) exhibited progressive hearing loss and showed signs of hair cell degeneration as early as two weeks of age, with fusion of stereocilia followed by complete loss of hair bundles and ultimately loss of hair cells. No changes in vestibular or neurological function, or other clinical or behavioral manifestations were apparent. Phosphoinositides are membrane associated signaling molecules that regulate many cellular processes including cell death, proliferation, actin polymerization and ion channel activity. These results reveal Synj2 as a critical regulator of hair cell survival that is essential for hair cell maintenance and hearing function.

Vowel production of Mandarin-speaking hearing aid users with different types of hearing loss.

Directory of Open Access Journals (Sweden)

Yu-Chen Hung

Full Text Available In contrast with previous research focusing on cochlear implants, this study examined the speech performance of hearing aid users with conductive (n = 11, mixed (n = 10, and sensorineural hearing loss (n = 7 and compared it with the speech of hearing control. Speech intelligibility was evaluated by computing the vowel space area defined by the Mandarin Chinese corner vowels /a, u, i/. The acoustic differences between the vowels were assessed using the Euclidean distance. The results revealed that both the conductive and mixed hearing loss groups exhibited a reduced vowel working space, but no significant difference was found between the sensorineural hearing loss and normal hearing groups. An analysis using the Euclidean distance further showed that the compression of vowel space area in conductive hearing loss can be attributed to the substantial lowering of the second formant of /i/. The differences in vowel production between groups are discussed in terms of the occlusion effect and the signal transmission media of various hearing devices.

Does tinnitus, hearing asymmetry, or hearing loss predispose to occupational injury risk?

Science.gov (United States)

Cantley, Linda F; Galusha, Deron; Cullen, Mark R; Dixon-Ernst, Christine; Tessier-Sherman, Baylah; Slade, Martin D; Rabinowitz, Peter M; Neitzel, Richard L

2015-02-01

To determine the relative contributions of tinnitus, asymmetrical hearing loss, low frequency hearing loss (pure tone average of 0.5, 1, 2, 3 kHz; PTA.5123), or high frequency hearing loss (pure tone average of 4, 6 kHz; PTA46), to acute injury risk among a cohort of production and maintenance workers at six aluminum manufacturing plants, adjusting for ambient noise exposure and other recognized predictors of injury risk. Retrospective analysis. The study considered 9920 workers employed during 2003 to 2008. The cohort consisted of 8818 workers (89%) whose complete records were available. Adjusting for noise exposure and other recognized injury predictors, a 25% increased acute injury risk was observed among workers with a history of tinnitus in conjunction with high-frequency hearing loss (PTA46). Low frequency hearing loss may be associated with minor, yet less serious, injury risk. We did not find evidence that asymmetry contributes to injury risk. These results provide evidence that tinnitus, combined with high-frequency hearing loss, may pose an important safety threat to workers, especially those who work in high-noise exposed environments. These at risk workers may require careful examination of their communication and hearing protection needs.

Time can be observed as a subjective, as well as an objective phenomenon which is a component of our life, and due to its communicational needs, it is standardized by temporal signs and symbols. The aim of this study was to determine the understanding of basic temporal relations of pupils with hearing impairments. We assumed that the knowledge of basic time relations is a precondition for the acquisition of knowledge that is connected with the understanding of the syllabus in regular school programs. Three groups of pupils have been examined: pupils with hearing impairments who attend the primary school of SUVAG Polyclinic under special condition, integrated hearing impaired pupils with minor additional difficulties who attend regular primary schools in Zagreb with a prolonged expert procedure and pupils of the control group. The subjects have been examined with a measuring instrument constructed by the expert team of the Polyclinic Suvag. Twenty nine subjects have been questioned, chronologically aged between 10 and 12.

2013-09-01

We sought to determine the outcome of implantation of a bone-anchored hearing device in children with unilateral conductive hearing loss. A retrospective case note analysis was used in a tertiary referral pediatric hospital to study 17 consecutive cases of pediatric patients with unilateral conductive hearing loss who were fitted with a bone-anchored hearing device between 2005 and 2010. The average age of the patients at the time of bone-anchored hearing device fitting was 10 years 6 months (range, 6 years 3 months to 16 years). Qualitative subjective outcome measures demonstrated benefit. The vast majority of patients reported improved social and physical functioning and improved quality of life. All 17 patients are currently using their bone-anchored hearing device on a daily basis after a follow-up of 6 months. This study has shown improved quality of life in children with unilateral hearing loss after implantation of their bone-anchored hearing device. There was a high degree of patient satisfaction and improvement in health status reported by children and/or carers. Bone-anchored hearing devices have an important role in the management of children with symptomatic unilateral hearing loss. Perhaps earlier consideration of a bone-anchored hearing device would be appropriate in selected cases.

To compare the auditory outcomes of Carina middle-ear implants with those of conventional hearing aids in patients with moderate-to-severe mixed hearing loss. The study comprised nine patients (six males, three females) who underwent middle-ear implantation with Carina fully implantable active middle-ear implants to treat bilateral moderate-to-severe mixed hearing loss. The patients initially used conventional hearing aids and subsequently received the Carina implants. The hearing thresholds with implants and hearing aids were compared. There were no significant differences between: the pre-operative and post-operative air and bone conduction thresholds (p > 0.05), the thresholds with hearing aids and Carina implants (p > 0.05), or the pre-operative (mean, 72.8 ± 19 per cent) and post-operative (mean, 69.9 ± 24 per cent) speech discrimination scores (p > 0.05). One of the patients suffered total sensorineural hearing loss three months following implantation despite an initial 38 dB functional gain. All except one patient showed clinical improvements after implantation according to quality of life questionnaire (Glasgow Benefit Inventory) scores. Acceptance of Carina implants is better than with conventional hearing aids in patients with mixed hearing loss, although both yield similar hearing amplification. Cosmetic reasons appear to be critical for patient acceptance.

during the fitting of hearing aids in children it is important, besides using a verification protocol, to have a validation process. to describe and discuss the use of a protocol for the fitting and the verification of hearing aids in children, as well as the impact of the adjustment of the acoustic characteristics in speech perception tasks. ten children aging from three to eleven years were enrolled in this study. All children presented bilateral sensorineural hearing impairment, were users of hearing aids and were followed at a public hearing health care service in Bahia. The children were submitted to the following procedures: pure tone air and bone conduction thresholds; real-ear coupler difference (RECD); verification with real-ear measurement equipment: coupler gain/output and insertion gain and to speech perception tasks: 'The Six-Sound Test' (Ling, 2006) and the 'Word Associations for Syllable Perception' (WASP - Koch, 1999). The programmed electro acoustic characteristics of the hearing aids were compared to the electro acoustic characteristics prescribed by the DSL [i/o] v4.1 software. The speech perception tasks were reapplied on three occasions: straight after the modification of the electro acoustic characteristics, after 30 days and 60 days. for more than 50% of the tested children, the programmed electro acoustic characteristics of the hearing aids did not correspond to that suggested by the DSL [i/o] software. Adequate prescription was verified in 70% of the investigated sample; this was also confirmed by the results in the speech perception tasks (p=0.000). This data confirmed that the mean percentage of correct answers increased after the modification of the electro acoustic characteristics. the use of a protocol that verifies and validates the fitting of hearing aids in children is necessary.

Muelheim-Kaerlich nuclear power station. Records of the hearing held in compliance with the atomic energy law, from December 5 to 13, 1989, in Muelheim-Kaerlich

International Nuclear Information System (INIS)

1990-04-01

The hearing reported here is the continuation of the first hearing held at the same place from August 28 to September 1, 1989. The legal examination of the hearing protocol had given rise to doubts concerning the reasonableness of recurity controls. In order not to jeopardize the purposes of the hearing, it was decided to hold another hearing in continuation of the first, so as to heal the deficiencies stated in connection with the first hearing. The second hearing offered the possibility of putting up again all items already discussed at the first hearing, and the subject matter of the December hearing was the same as that of the August hearing, so that the hearing fully met the requirements defined in sections 8 ff, of the Nuclear Installations Ordinance for a legally unobjectionable hearing. Provision was made for all objections and detail raised in the hearings to be taken into account in the licensing procedure. (orig./HP) [de

The use of acoustic signals to mask, mix with, or ease the distress associated with tinnitus has been clinically employed for decades. It has been proposed that expanding acoustic options for tinnitus sufferers due to personal preferences is desirable. Fractal tones incorporate many useful characteristics of music while avoiding certain features that could be distracting to some individuals. To assess the effects on relaxation, tinnitus annoyance, tinnitus handicap, and tinnitus reaction from the use of a hearing aid that incorporates combinations of amplification, fractal tones, and white noise. Participants listened to experimental hearing aids containing several acoustic options and were asked to rate the signals in terms of their effect on relaxation and tinnitus annoyance. They subsequently wore the hearing aids for 6 mo and completed tinnitus handicap and reaction scales. Fourteen hearing-impaired adults with primary complaints of subjective tinnitus. Participants were tested wearing hearing aids containing several programs including amplification only, fractal tones only, and a combination of amplification, noise, and/or fractal tones. The fractal tones (now commercially available as the "Zen" feature) were generated by the Widex Mind hearing aid. Rating procedures were conducted in the laboratory, and tinnitus reaction and handicap were assessed during and following a 6 mo field trial. Data were collected at the initial visit, one week, 1 mo, 3 mo, and 6 mo. Nonparametric statistics included Wilcoxon matched-pairs signed-rank, chi(2), and repeated-measures analyses of variance. Thirteen of 14 participants reported that their tinnitus annoyance, as measured by the Tinnitus Annoyance Scale, was reduced for at least one of the amplified conditions (with or without fractal tones or noise), relative to the unaided condition. Nine assigned a lower tinnitus annoyance rating when listening to fractal tones alone versus the amplification-alone condition. There was a

Introduction Noise-induced hearing loss (NIHL) is a serious problem for workers and therefore for businesses. The hearing conservation program (HCP) is a set of coordinated measures to prevent the development or evolution of occupational hearing loss, which involves a continuous and dynamic process of implementation of hearing conservation routines through anticipation, recognition, evaluation, and subsequent control of the occurrence of existing environmental risks or of those that may exist in the workplace and lead to workers' hearing damage. Objective The aim of this study was to evaluate the effectiveness of the HCP in preventing further hearing loss in workers with audiograms suggestive of NIHL. The audiometric tests and medical records of 28 furniture company workers exposed to noise were reviewed and monitored for 2 years. Methods This retrospective, cross-sectional study examined five audiometric tests in the medical records (on admission and every semester) of 28 workers in a furniture company (totaling 140 audiometric exams) following the introduction of the HCP. Results Data analysis showed no differences between the audiometric tests conducted on admission and those performed every semester. Conclusions The HCP implemented was effective in preventing the worsening of hearing loss in workers already with NIHL when exposed to occupational noise. Therefore, such a measure could be useful for the employment of workers with hearing loss in job sectors that have noise exposure.

2015-03-01

Full Text Available The first part of this paper argued the desirability of structural-dynamic model of emotion regulation in the theoretical and methodological framework of cultural activity paradigm with the construction of a psychologically-based typology of emotion regulation strategies in norm and pathology, and also psychological mechanisms enabling the regulation of emotions. This conclusion was based on the analysis of the basic concepts and paradigms in which the issue of emotion regulation is studied: cognitive and psychoanalytic approaches, concept and emotional development of emotional intelligence, cultural activity approach. The paper considers the procedure model of emotion regulation by J. Gross, identifies emotion regulation strategies and evaluates their effectiveness. The possibilities and limitations of the model. Based on the review of the today research the conclusion is arrived at that the existing labels on a wide range of regulatory strategies remain an open issue.The author’s definition of emotion regulation is drawn. Emotion regulation is deemed as a set of mental processes, psychological mechanisms and regulatory strategies that people use to preserve the capacity for productive activities in a situation of emotional stress; to ensure optimal impulse control and emotions; to maintain the excitement at the optimum level. The second part of this paper provides the general description of emotion regulation strategies, the approach to their typology, the psychological mechanisms of emotion regulation that lie in the basis of this typology, i.e. the main elements of the structural-dynamic model of emotion regulation. The work shows theoretical and methodological efficacy of empirical significance of signs and symbols and also personal reflection. The diagnostic system to allow empirically identify a wide range of emotion regulation strategies is suggested. The psychological mechanisms used by the subject to solve the problem of emotional

Age-related hearing loss: Aquaporin 4 gene expression changes in the mouse cochlea and auditory midbrain

Science.gov (United States)

Christensen, Nathan; D'Souza, Mary; Zhu, Xiaoxia; Frisina, Robert D.

2009-01-01

Presbycusis – age-related hearing loss, is the number one communication disorder, and one of the top three chronic medical conditions of our aged population. Aquaporins, particularly aquaporin 4 (Aqp4), are membrane proteins with important roles in water and ion flux across cell membranes, including cells of the inner ear and pathways of the brain used for hearing. To more fully understand the biological bases of presbycusis, 39 CBA mice, a well-studied animal model of presbycusis, underwent non-invasive hearing testing as a function of sound frequency (auditory brainstem response – ABR thresholds, and distortion-product otoacoustic emission – DPOAE magnitudes), and were clustered into four groups based on age and hearing ability. Aqp4 gene expression, as determined by genechip microarray analysis and quantitative real-time PCR, was compared to the young adult control group in the three older groups: middle aged with good hearing, old age with mild presbycusis, and old age with severe presbycusis. Linear regression and ANOVA showed statistically significant changes in Aqp4 gene expression and ABR and DPOAE hearing status in the cochlea and auditory midbrain – inferior colliculus. Down-regulation in the cochlea was seen, and an initial down-, then up-regulation was discovered for the inferior colliculus Aqp4 expression. It is theorized that these changes in Aqp4 gene expression represent an age-related disruption of ion flux in the fluids of the cochlea that are responsible for ionic gradients underlying sound transduction in cochlear hair cells necessary for hearing. In regard to central auditory processing at the level of the auditory midbrain, aquaporin gene expression changes may affect neurotransmitter cycling involving supporting cells, thus impairing complex sound neural processing with age.

Changes in auditory perceptions and cortex resulting from hearing recovery after extended congenital unilateral hearing loss

Directory of Open Access Journals (Sweden)

Jill B Firszt

2013-12-01

Full Text Available Monaural hearing induces auditory system reorganization. Imbalanced input also degrades time-intensity cues for sound localization and signal segregation for listening in noise. While there have been studies of bilateral auditory deprivation and later hearing restoration (e.g. cochlear implants, less is known about unilateral auditory deprivation and subsequent hearing improvement. We investigated effects of long-term congenital unilateral hearing loss on localization, speech understanding, and cortical organization following hearing recovery. Hearing in the congenitally affected ear of a 41 year old female improved significantly after stapedotomy and reconstruction. Pre-operative hearing threshold levels showed unilateral, mixed, moderately-severe to profound hearing loss. The contralateral ear had hearing threshold levels within normal limits. Testing was completed prior to, and three and nine months after surgery. Measurements were of sound localization with intensity-roved stimuli and speech recognition in various noise conditions. We also evoked magnetic resonance signals with monaural stimulation to the unaffected ear. Activation magnitudes were determined in core, belt, and parabelt auditory cortex regions via an interrupted single event design. Hearing improvement following 40 years of congenital unilateral hearing loss resulted in substantially improved sound localization and speech recognition in noise. Auditory cortex also reorganized. Contralateral auditory cortex responses were increased after hearing recovery and the extent of activated cortex was bilateral, including a greater portion of the posterior superior temporal plane. Thus, prolonged predominant monaural stimulation did not prevent auditory system changes consequent to restored binaural hearing. Results support future research of unilateral auditory deprivation effects and plasticity, with consideration for length of deprivation, age at hearing correction, degree and type

2017-09-01

Full Text Available Introduction and Aim In the life of every human senses, including the sense of hearing, they play an important role in the harmonious development. Each hearing loss in childhood influences, depending on the depth, nature and time of its inception, in a negative way on the development of many mental activities, intellectual, behavior, cognitive, causing significant impairment in the child's position the hearing impaired, deaf and especially in the world of the hearing. The aim of this study is to assess the parents' awareness of hearing loss in children with hearing loss as a result of a survey of parents of children from the first classes of primary schools in the Lublin province. Material and Methods Analysis was performed on 31 results of parents of children with hearing impairment made in children aged 6 and 7 years, pupils and primary schools in the Lublin province. Parents were asked the question: 'Do you think your child has hearing problems?' The analysis indicated the assessment of awareness of parents of children with hearing disorders.   Results In the study group, as many as 77% of parents stated that the child does not have problems with hearing, only 3% of parents noted the problem, while 20% of parents did not answer the question. Conclusions Based on the research it can be stated with a high percentage of parents still do not notice hearing loss in their children. Early notice of the problem, the correct procedure and the cooperation with the parent group of specialists are often the way to success. It is crucial to support the child in difficult situations, which often is exposed to contact with all sorts of obstacles. An important issue is the numerous health programs, shaping the attitude of parents and society as a whole.

Self-Assessment of Hearing and Purchase of Hearing Aids by Middle-Aged and Elderly Adults

Directory of Open Access Journals (Sweden)

Otavio, Andressa Colares da Costa

2015-06-01

Full Text Available Introduction Presbycusis is a consequence of aging. Prescription of hearing aids is part of the treatment, although the prevalence of use by elderly people is still small. Objective To verify whether or not self-assessment of hearing is a predictor for purchase of hearing aids. Methods Quantitative, cross-sectional, descriptive, and observational study. Participants were subjects who sought a private hearing center for selection of hearing aids. During the diagnostic interview, subjects answered the following question: “On a scale of 1 to 10, with 1 being the worst and 10 the best, how would you rate your overall hearing ability?” After that, subjects underwent audiometry, selected a hearing aid, performed a home trial, and decided whether or not to purchase the hearing aid. The variables were associated and analyzed statistically. Results The sample was comprised of 32 subjects, both men and women, with a higher number of women. Mean age was 71.41 ± 12.14 years. Self-assessment of hearing ranged from 2 to 9 points. Overall, 71.9% of the subjects purchased hearing aids. There was no association between scores in the self-assessment and the purchase of hearing aids (p = 0.263. Among those who scored between 2 and 5 points, 64.7% purchased the device; between 6 and 7 points, 76.09% purchased the device; and between 8 and 9 points, 50% purchased the device, respectively. Conclusion There is evidence that low self-assessment scores lead to the purchase of hearing aids, although no significant association was observed in the sample.

2009-04-01

More than 80% of permanent hearing losses (HL) in children are congenital. Newborn hearing screening (NHS) is the best method for early detection of suspected hearing loss. If the NHS is not universal more than 30% permanent hearing losses are not identified. There are various methods of NHS: otoacoustic emissions (TEOAE, DPOAE) and automatic auditory brainstem response (AABR). After hearing screening, and when hearing loss is suspected, tympanometry and audiological methods then used for determination of hearing threshold; these include ABR, ASSR or/and behavioral methods. The goal of this study is to evaluate the influence of UNHS on the early detection of hearing loss in children before and after the implementation of obligatory universal newborn hearing screening in Slovakia, and also on the etiologic evaluation of hearing impaired infants identified by screening. In Slovakia NHS started in 1998 and was provided in ENT departments. From May 1, 2006 UNHS has been mandatory in Slovakia, using two stages TEOAE in all newborn departments in Slovakia (64 newborn departments). In year 2005--42% of newborns in Slovakia were screened, in 2006--66% newborns and in 2007--94, 99% (three small newborn departments do not yet have equipment for OAE screening). For determination of hearing thresholds ASSR are used in two ENT departments and ABR in the other four ENT departments. Comparing the number of identified cases with bilateral severe permanent HL or deafness before and after UNHS, 22.8% more cases of PHL were identified in the first year of UNHS. Also the average age of diagnosis of PHL was lower. In the year 2007, 94% of newborns were screened. We found 0.947/1000 newborns with bilateral severe PHL (35.9%) more than before UNHS). After audiologic and etiologic assessment of the 76 infants who failed screening, 5 (6.58%) were found to have normal hearing, 16 (22.54%) had unilateral and 55 (77.46%) had bilateral SNHL. A non-syndromic genetic cause was present in 25

Pure tone audiograms and possible aminoglycoside-induced hearing loss in belugas (Delphinapterus leucas)

2005-06-01

A behavioral response paradigm was used to measure pure-tone hearing sensitivities in two belugas (Delphinapterus leucas). Tests were conducted over a 20-month period at the Point Defiance Zoo and Aquarium, in Tacoma, WA. Subjects were two males, aged 8-10 and 9-11 during the course of the study. Subjects were born in an oceanarium and had been housed together for all of their lives. Hearing thresholds were measured using a modified up/down staircase procedure and acoustic response paradigm where subjects were trained to produce audible responses to test tones and to remain quiet otherwise. Test frequencies ranged from approximately 2 to 130 kHz. Best sensitivities ranged from approximately 40 to 50 dB re 1 μPa at 50-80 kHz and 30-35 kHz for the two subjects. Although both subjects possessed traditional ``U-shaped'' mammalian audiograms, one subject exhibited significant high-frequency hearing loss above 37 kHz compared to previously published data for belugas. Hearing loss in this subject was estimated to approach 90 dB for frequencies above 50 kHz. Similar ages, ancestry, and environmental conditions between subjects, but a history of ototoxic drug administration in only one subject, suggest that the observed hearing loss was a result of the aminoglycoside antibiotic amikacin. .

Full Text Available In determinate the transfer prices, The Romanian Procedural Fiscal Code stipulates (in the 79th article the obligation for those contributors who make transactions with related entities to draw up a record of transfer prices and to forward it to the tax administrations (at their request. Currently, the UE member states seek harmonization of tax legislation, with the aim of creating a common tax base. An important effect of the common base would be giving up the requirement for compiling a transfer price record, because the realization of income in a member state shall be associated with expenses in the state where the affiliate is located. In Romania, the guidelines on transfer pricing developed by the OECD have been assimilated into the domestic tax regulations (although our country is not yet a member of OECD, in order to harmonize these regulations in the Community. The main effect globalization has on transfer prices is increasing their complexity, as, in fact, economic globalization is reason for the existence of transfer pricing. With the increasing complexity of this area, states are forced either to improve legislation, or to create it, in order to ensure the growth of states income taxes.

Comparison of reading comprehension and working memory in hearing-impaired and normal-hearing children

Directory of Open Access Journals (Sweden)

Mohammad Rezaei

2013-03-01

Full Text Available Background and Aim: Reading is the most important human need for learning. In normal-hearing people working memory is a predictor of reading comprehension. In this study the relationship between working memory and reading comprehension skills was studied in hearing-impaired children, and then compared with the normal-hearing group.Methods: This was a descriptive-analytic study. The working memory and reading comprehension skills of 18 (8 male, 10 female sever hearing-impaired children in year five of exceptional schools were compared by means of a reading test with 18 hearing children as control group. The subjects in the control group were of the same gender and educational level of the sample group.Results: The children with hearing loss performed similarly to the normal-hearing children in tasks related to auditory-verbal memory of sounds (reverse, visual-verbal memory of letters, and visual-verbal memory of pictures. However, they showed lower levels of performance in reading comprehension (p<0.001. Moreover, no significant relationship was observed between working memory and reading comprehension skills.Conclusion: Findings indicated that children with hearing loss have a significant impairment in the reading comprehension skill. Impairment in language knowledge and vocabulary may be the main cause of poor reading comprehension in these children. In hearing-impaired children working memory is not a strong predictor of reading comprehension.

Influence of Loudness Compression on Hearing with Bone Anchored Hearing Implants

OpenAIRE

Kurz, Anja; Caversaccio, Marco; Kompis, Martin; Flynn, Marc

2014-01-01

Bone Anchored Hearing Implants (BAHI) are routinely used in patients with conductive or mixed hearing loss, e.g. if conventional air conduction hearing aids cannot be used. New sound processors and new fitting software now allow the adjustment of parameters such as loudness compression ratios or maximum power output separately. Today it is unclear, how the choice of these parameters influences aided speech understanding in BAHI users. In this prospective experimental study, the effect ...

Al-Hilawani, Y A

2000-09-01

The purpose of this study was to examine the influence of using the Cognitive Behaviour Modification (CBM) technique on the subtraction skills of third grade hearing and deaf/hard-of-hearing students. The results indicated that the CBM deaf/hard-of-hearing students and the CBM and non-CBM hearing students made more progress in solving the subtraction problems than the non-CBM deaf/hard-of-hearing students. The results also showed that there were no significant differences between the CBM deaf/hard-of-hearing and the non-CBM hearing students; and there were no significant differences between the CBM and non-CBM hearing students. The results revealed that the CBM hearing students achieved significantly higher post-test scores than the CBM deaf/hard-of-hearing students. However, the CBM deaf/hard-of-hearing students obtained a significantly higher gain score compared to the CBM and non-CBM hearing students. Implications for teachers and suggestions for future research are discussed in this paper.

Noise is now the most serious health hazard in industry. People risk suffering severe damage to their hearing and health generally through exposure to noise levels which exceed the risk limit of 95-90 dB(A). Stress related problems are often directly the result of exposure to noise. Furthermore, noise leads to reduced productivity, increased absenteeism and compensation claims. In a series of eight reports, Bilson technologists detail the specific noise problems commonly encountered in each of the major areas of industry. These range from the concrete and construction industry through sawmilling, wood working, mining and mechanical engineering, to textile and food manufacture. This report discusses the noise in mining, considering drills, load haul dump machines, surface mines, earth moving equipment, treatment plants, frequency spectra of noise, and finally, choice of hearing protection.

For the power industry which is 'independent of licensing', the Ule/Laubinger statement as well as its discussion on the 52th German legal experts' day are of considerable importance. It is therefore absolutely necessary to critically investigate the statements of this expert's opinion and the considerations on which they are based. This investigation is limited to those licensing procedures which in the terminology of experts, are 'similar to the plan approval procedure'. This applies mainly to the procedures according to paragraph 4 ff of the Federal Act on the Protection Against Nuisances and paragraph 7 of the Atomic Energy Law: Preliminaries publication of documents, inspection of files, public hearing, taking of evidence, persons with special responsibilities, administrative proceedings, actions by associations. The deficiencies in the execution of environmental procedural law is briefly mentioned. The notes in the article refer only to air pollution. (orig./HP) [de

This investigation examined whether speech intelligibility in noise can be improved using a new, binaural broadband hearing instrument system. Participants were 36 adults with symmetrical, sensorineural hearing loss (18 experienced hearing instrument users and 18 without prior experience). Participants were fit binaurally in a planned comparison, randomized crossover design study with binaural broadband hearing instruments and advanced digital hearing instruments. Following an adjustment period with each device, participants underwent two speech-in-noise tests: the QuickSIN and the Hearing in Noise Test (HINT). Results suggested significantly better performance on the QuickSIN and the HINT measures with the binaural broadband hearing instruments, when compared with the advanced digital hearing instruments and unaided, across and within all noise conditions.

Smith, Scott R.; Samar, Vincent J.

2016-01-01

Deaf and hard-of-hearing (D/HH) adults have lower health literacy compared to hearing adults but it is unclear if this disparity also occurs in adolescence. We used the Health Literacy Skills Instrument-Short Form (HLSI-SF), Short Form of the Test of Functional Health Literacy (S-TOFHLA), Comprehensive Heart Disease Knowledge Questionnaire (CHDKQ) and newly constructed interactive and critical health literacy survey items to quantify D/HH and hearing adolescents’ health literacy. We adapted and translated survey materials into sign language and spoken English to reduce testing bias due to variable English language skills. Participants were 187 D/HH and 94 hearing college-bound high school students. Adjusting for age, gender, race/ethnicity, school grade, and SES, D/HH adolescents demonstrated weaker general and functional health literacy and cardiovascular health knowledge than hearing adolescents on the HLSI, S-TOFHLA, and CHDKQ (all p’s<.0001). Standard health literacy or knowledge scores were associated with several interactive and critical health literacy skills (all p’s<.05). D/HH adolescents who reported greater hearing-culture identity, having hearing aids, experiencing better hearing with assistive devices, having good quality of communication with parents, and attending hearing schools at least half of the time had higher functional health literacy (all p’s<.025). Those who reported English as their best language and attending hearing schools at least half the time had higher cardiovascular health knowledge scores (all p’s< .03). Results suggest that interventions to improve D/HH adolescents’ health literacy should target their health-related conversations with their families, access to printed health information, and access to health information from other people, especially health care providers and educators.

Purpose: Vestibular schwannomas (VS) are increasingly diagnosed in patients with normal hearing because of advances in magnetic resonance imaging. We sought to evaluate whether stereotactic radiosurgery (SRS) performed earlier after diagnosis improved long-term hearing preservation in this population. Methods and Materials: We queried our quality assessment registry and found the records of 1134 acoustic neuroma patients who underwent SRS during a 15-year period (1997-2011). We identified 88 patients who had VS but normal hearing with no subjective hearing loss at the time of diagnosis. All patients were Gardner-Robertson (GR) class I at the time of SRS. Fifty-seven patients underwent early (≤2 years from diagnosis) SRS and 31 patients underwent late (>2 years after diagnosis) SRS. At a median follow-up time of 75 months, we evaluated patient outcomes. Results: Tumor control rates (decreased or stable in size) were similar in the early (95%) and late (90%) treatment groups (P=.73). Patients in the early treatment group retained serviceable (GR class I/II) hearing and normal (GR class I) hearing longer than did patients in the late treatment group (serviceable hearing, P=.006; normal hearing, P<.0001, respectively). At 5 years after SRS, an estimated 88% of the early treatment group retained serviceable hearing and 77% retained normal hearing, compared with 55% with serviceable hearing and 33% with normal hearing in the late treatment group. Conclusions: SRS within 2 years after diagnosis of VS in normal hearing patients resulted in improved retention of all hearing measures compared with later SRS.

2007-01-01

We evaluated the correlation of asymmetric hearing loss, in a random population of patients with mild to moderate sensorineural hearing loss, to several clinical factors such as age, sex, handedness, and noise exposure. We randomly selected, from 8 hearing institutes in Israel, 429 patients with sensorineural hearing loss of at least 30 dB at one frequency and a speech reception threshold not exceeding 30 dB. Patients with middle ear disease or retrocochlear disorders were excluded. The results of audiometric examinations were compared binaurally and in relation to the selected factors. The left ear's hearing threshold level was significantly higher than that of the right ear at all frequencies except 1.0 kHz (p < .05). One hundred fifty patients (35%) had asymmetric hearing loss (more than 10 dB difference between ears). In most of the patients (85%) the binaural difference in hearing threshold level, at any frequency, was less than 20 dB. Age, handedness, and sex were not found to be correlated to asymmetric hearing loss. Noise exposure was found to be correlated to asymmetric hearing loss.

Hearing Loss: Issues in the Deaf and Hard of Hearing Communities.

Science.gov (United States)

Moreland, Christopher; Atcherson, Samuel R; Zazove, Philip; McKee, Michael M

2015-07-01

Hearing loss can lead to impairments in language and speech acquisition, educational attainment, social development, and reading achievement. More than 90% of deaf and hard of hearing (DHH) children are born to hearing parents who may lack the knowledge or experience to effectively care for a child with hearing loss. Family involvement is crucial for teaching self-advocacy and global communication skills, optimizing social development, and helping DHH individuals understand and manage external attitudes about deafness and hearing loss. American Sign Language is a naturally developed language with an always-expanding lexicon and grammatical structures different from those of English. Teaching spoken English and American Sign Language equally, often called bilingual bimodal education, can enhance academic and reading achievement as well as language and psychosocial development. Formal schooling options for a DHH child include enrollment in a public or private school system (often called inclusion, integration, or mainstreaming), a school for the deaf, or a bilingual school. Individuals with hearing loss experience stereotypes and biases that create disparities in health insurance coverage, health care access, and outcomes of mental and physical conditions. Family physicians should recognize and minimize biases to improve health care in the DHH community.

Classification of Hearing Loss Disorders Using Teoae-Based Descriptors

Science.gov (United States)

Hatzopoulos, Stavros Dimitris

Transiently Evoked Otoacoustic Emissions (TEOAE) are signals produced by the cochlea upon stimulation by an acoustic click. Within the context of this dissertation, it was hypothesized that the relationship between the TEOAEs and the functional status of the OHCs provided an opportunity for designing a TEOAE-based clinical procedure that could be used to assess cochlear function. To understand the nature of the TEOAE signals in the time and the frequency domain several different analyses were performed. Using normative Input-Output (IO) curves, short-time FFT analyses and cochlear computer simulations, it was found that for optimization of the hearing loss classification it is necessary to use a complete 20 ms TEOAE segment. It was also determined that various 2-D filtering methods (median and averaging filtering masks, LP-FFT) used to enhance of the TEOAE S/N offered minimal improvement (less than 6 dB per stimulus level). Higher S/N improvements resulted in TEOAE sequences that were over-smoothed. The final classification algorithm was based on a statistical analysis of raw FFT data and when applied to a sample set of clinically obtained TEOAE recordings (from 56 normal and 66 hearing-loss subjects) correctly identified 94.3% of the normal and 90% of the hearing loss subjects, at the 80 dB SPL stimulus level. To enhance the discrimination between the conductive and the sensorineural populations, data from the 68 dB SPL stimulus level were used, which yielded a normal classification of 90.2%, a hearing loss classification of 87.5% and a conductive-sensorineural classification of 87%. Among the hearing-loss populations the best discrimination was obtained in the group of otosclerosis and the worst in the group of acute acoustic trauma.

Sensorineural hearing loss in children.

The objective of the study was to examine the aetiology of sensorineural hearing loss (SNHL) in a paediatric population presenting to the National Centre of Medical Genetics. A retrospective chart review from 1998 to 2006. One hundred and twenty nine children were investigated for SNHL. The average age of diagnosis of hearing loss was 36 months. The degree of hearing loss was mild in 8 children, moderate in 33 children, severe in 31 children and profound in 57 children. Eighty-five children (66%) were diagnosed with a hereditary hearing loss, 11 (8%) children had an acquired hearing loss and no cause found in 33 (26%) children. This is the first report of the causes of hearing loss in Irish children. The mean age of diagnosis in our cohort is high and emphasises the need for a neonatal screening programme. There remains a number of children for whom the cause of hearing loss remains unknown.

about the screening (M = 2.90/5.0, SD = 1.27), screening procedure (M = 2.20/5.0, SD = 1.08), and sufficiency of information about results (M = 2.87/5.0, SD = 1.14). Nonetheless, participants gave positive ratings concerning whether screening could lead to early diagnosis (M = 4.61/5.0, SD = 0.57) and over 95% of mothers supported UNHS despite potential for false positive results. Mothers reported a high willingness to bring their baby to follow-up assessments if required (M = 4.53/5.0, SD = 0.56). Participants gave positive ratings for their level of satisfaction with the time and location of first UNHS information provision (M = 4.34/5.0, SD = 0.80) and the way permission was asked for screening the baby (M = 4.04/5.0, SD = 0.97) but alternative procedures were also recommended. Most recommendations focused on providing more information about the test and a more detailed explanation of screening results. The survey results highlighted the need to provide more information to parents about infant hearing development to support home monitoring for signs of hearing loss after UNHS, as well as more detailed explanation and information regarding hearing screening and the implications of results to parents. Regardless of location, surveys of this type may provide valuable support for UNHS program quality assurance. Copyright © 2017. Published by Elsevier B.V.

Age-related Hearing Impairment and the Triad of Acquired Hearing Loss

Directory of Open Access Journals (Sweden)

Chao-Hui eYang

2015-07-01

Full Text Available Understanding underlying pathological mechanisms is prerequisite for a sensible design of protective therapies against hearing loss. The triad of age-related, noise-generated, and drug-induced hearing loss ¬¬displays intriguing similarities in some cellular responses of cochlear sensory cells such as a potential involvement of reactive oxygen species and apoptotic and necrotic cell death. On the other hand, detailed studies have revealed that molecular pathways are considerably complex and, importantly, it has become clear that pharmacological protection successful against one form of hearing loss will not necessarily protect against another. This review will summarize pathological and pathophysiological features of age-related hearing impairment (ARHI in human and animal models and address selected aspects of the commonality (or lack thereof of cellular responses in ARHI to drugs and noise.

Occupational hearing loss is one of the most common work-related illnesses in the United States (US). From 22 to 30 million US workers are exposed to hazardous noise levels at work, and 25% of these workers will develop permanent hearing loss. Hearing loss from noise is slow and painless, and you can have a disability before you notice it. This course presents the hazards associated with workplace noise, the purpose and elements of the Los Alamos National Laboratory (LANL) Hearing Conservation Program (HCP), and controls that are available to reduce your exposure to hazardous levels of noise.

Rosa, Francisco; Coutinho, Miguel Bebiano; Ferreira, João Pinto; Sousa, Cecilia Almeida

2016-01-01

The aim of this study was to assess the main ear malformations, hearing loss and auditory rehabilitation in children with Treacher Collins syndrome. We performed a retrospective study of 9 children with Treacher Collins syndrome treated in a central hospital between January 2003 and January 2013. This study showed a high incidence of malformations of the outer and middle ear, such as microtia, atresia or stenosis of the external auditory canal, hypoplastic middle ear cavity, dysmorphic or missing ossicular chain. Most patients had bilateral hearing loss of moderate or high degree. In the individuals studied, there was functional improvement in patients with bone-anchored hearing aids in relation to conventional hearing aids by bone conduction. Treacher Collins syndrome is characterized by bilateral malformations of the outer and middle ear. Hearing rehabilitation in these children is of utmost importance, and bone-anchored hearing aids is the method of choice.

Decline of Low-Frequency Hearing in People With Ski-Slope Hearing Loss; Implications for Electrode Array Insertion.

Science.gov (United States)

Schuurbiers, Jasper; Dingemanse, Gertjan; Metselaar, Mick

2017-12-01

The decline of low-frequency hearing in people with ski-slope hearing loss varies and might depend on etiology. People with ski-sloping hearing loss might benefit from cochlear implantation with preservation of residual hearing. To reduce the risk of losing low-frequency hearing after implantation, the electrode-array can be inserted partially up to the desired frequency. That, however, obstructs electrical stimulation of lower frequencies. To decide between complete or partial insertion, knowledge regarding the natural decline of low-frequency hearing is helpful. Patients with at least two ski-slope audiograms over time were selected. We calculated progression at lower frequencies for 320 patients. Etiologies for hearing loss were retrieved from medical records. Progression of hearing loss was analyzed separately for patients with uni- and bilateral hearing losses. Relative progression of hearing loss was obtained by comparing progression to a reference group. Average progression of PTA was 1.73 dB/yr and was not significantly different in the bilateral and unilateral group. Etiologies that did not show significantly more progression compared with the reference group could be identified as single or short-lasting pathologic events, whereas long-lasting conditions had significant more progression of PTA. Patients with a ski-slope hearing loss that was caused by a single or short-lasting event have low progression rate and are viable for partial insertion to minimize the risk of damaging residual low-frequency hearing. In the absence of such an event, complete insertion should be considered because faster than normal deterioration of low-frequency hearing over time will probably limit the advantage of preservation of residual hearing.

Occupationally-acquired noise-induced hearing loss: a senseless workplace hazard.

Science.gov (United States)

Kurmis, Andrew P; Apps, Stacey A

2007-01-01

Occupational noise-induced hearing loss (ONIHL) describes an acquired hearing deficiency directly attributable to excessive workplace noise exposure. Data suggest that excessive noise attributes to approximately 37% of all adult causes of hearing loss and remains a significant contributor to employment-related morbidity internationally. Typically insidiously-acquired, often without frank progressive symptomatology, regional medical agencies continue to struggle with this potentially debilitating condition. The aim of the study was to provide a synopsis of the current understanding of ONIHL, its impact on individual workers and the wider international community, and to identify barriers to more uniform adoption of personal hearing protection. A review of the contemporary literature was performed using defined keyword searches and OVID, PubMed, and Google Scholar as primary electronic search engines. A number of published works were identified, describing aspects of the relationship between workplace-related noise exposure and subsequent development of employee hearing impairment, which demonstrate an overwhelming gender imbalance, with up to 97% of affected individuals being male. Industry-specific associations (e.g., mining, manufacturing and heavy construction) were well documented, as were links to toxin-specific exposures, in the recognized development of hearing loss. However, evidence of integration of appraisal of the topically-current area of genetic susceptibility was often lacking. Much discordance still exists among international agencies in the prescriptive regulation and enforcement of "safe" exposure limits. Despite a high level of public awareness regarding the importance of hearing preservation and increasingly stringent international occupational health, safety and welfare requirements mandating provision of safer work environments, ONIHL continues to be a significant occupational hazard. ONIHL is permanent and may cause significant disability, for

Potgieter, Jenni-Marí; Swanepoel, De Wet; Myburgh, Hermanus Carel; Hopper, Thomas Christopher; Smits, Cas

2015-07-01

The objective of this study was to develop and validate a smartphone-based digits-in-noise hearing test for South African English. Single digits (0-9) were recorded and spoken by a first language English female speaker. Level corrections were applied to create a set of homogeneous digits with steep speech recognition functions. A smartphone application was created to utilize 120 digit-triplets in noise as test material. An adaptive test procedure determined the speech reception threshold (SRT). Experiments were performed to determine headphones effects on the SRT and to establish normative data. Participants consisted of 40 normal-hearing subjects with thresholds ≤15 dB across the frequency spectrum (250-8000 Hz) and 186 subjects with normal-hearing in both ears, or normal-hearing in the better ear. The results show steep speech recognition functions with a slope of 20%/dB for digit-triplets presented in noise using the smartphone application. The results of five headphone types indicate that the smartphone-based hearing test is reliable and can be conducted using standard Android smartphone headphones or clinical headphones. A digits-in-noise hearing test was developed and validated for South Africa. The mean SRT and speech recognition functions correspond to previous developed telephone-based digits-in-noise tests.

Smartphone-Based Hearing Screening in Noisy Environments

Directory of Open Access Journals (Sweden)

Youngmin Na

2014-06-01

Full Text Available It is important and recommended to detect hearing loss as soon as possible. If it is found early, proper treatment may help improve hearing and reduce the negative consequences of hearing loss. In this study, we developed smartphone-based hearing screening methods that can ubiquitously test hearing. However, environmental noise generally results in the loss of ear sensitivity, which causes a hearing threshold shift (HTS. To overcome this limitation in the hearing screening location, we developed a correction algorithm to reduce the HTS effect. A built-in microphone and headphone were calibrated to provide the standard units of measure. The HTSs in the presence of either white or babble noise were systematically investigated to determine the mean HTS as a function of noise level. When the hearing screening application runs, the smartphone automatically measures the environmental noise and provides the HTS value to correct the hearing threshold. A comparison to pure tone audiometry shows that this hearing screening method in the presence of noise could closely estimate the hearing threshold. We expect that the proposed ubiquitous hearing test method could be used as a simple hearing screening tool and could alert the user if they suffer from hearing loss.

1986-01-01

Two days of hearings held to consider three bills which would reform nuclear power plant regulation stressed the fact that there has been no resolution of many of the problems identified after the Three Mile Island accident. Principal witnesses were Nunzio Palladino and other members and former members of the Nuclear Regulatory Commission (NRC) and representatives of electric utilities, public utility commissions, citizen groups, and the legal profession. One aspect of current procedures which is not working is meetings held in compliance with sunshine laws. At issue was the process of collegial decision making and whether a structure with a single administrator would better sever the public. NRC commissioners concur that collegial decision making is less efficient, but oppose S. 2291's proposal for an independent Nuclear Safety Board. The tests of S. 1235, S. 2291, and S. 2471 accompany the recorded testimony

2018-03-01

To analyze 2007 Joint Committee on Infant Hearing (JCIH) risk factors in children with confirmed unilateral hearing loss (UHL) who initially passed newborn hearing screening. Retrospective record review of 16,108 infants who passed newborn hearing screening but had one or more JCIH risk factors prompting subsequent follow-up through the universal newborn hearing screening (UNHS) program in Virginia from 2010 to 2012. The study was reviewed and qualified as exempt by the Virginia Commonwealth University Institutional Review Board (IRB) and the Virginia Department of Health. Over the 2-year study period, 14896 (4.9% of total births) children passed UNHS but had the presence of one or more JCIH risk factor. Ultimately, we identified 121 babies from this group with confirmed hearing loss (0.7%), with 48 babies (0.2%) showing UHL. The most common risk factors associated with the development of confirmed UHL after passing the initial screen were neonatal indicators, craniofacial anomalies, family history, and stigmata of syndrome associated with hearing loss. Neonatal indicators and craniofacial anomalies were the categories most often found in children with confirmed unilateral hearing loss who initially passed their newborn hearing screen. While neonatal indicators were also the most common associated risk factor in all hearing loss, craniofacial abnormalities are relatively more common in children with UHL who initially passed newborn hearing screening. Further studies assessing the etiology underlying the hearing loss and risk factor associations are warranted. Copyright © 2018 Elsevier B.V. All rights reserved.

Transforming growth factor β1 inhibition protects from noise-induced hearing loss

Directory of Open Access Journals (Sweden)

Silvia eMurillo-Cuesta

2015-03-01

Full Text Available Excessive exposure to noise damages the principal cochlear structures leading to hearing impairment. Inflammatory and immune responses are central mechanisms in cochlear defensive response to noise but, if unregulated, they contribute to inner ear damage and hearing loss. Transforming growth factor ß (TGF-ß is a key regulator of both responses and high levels of this factor have been associated with cochlear injury in hearing loss animal models. To evaluate the potential of targeting TGF-ß as a therapeutic strategy for preventing or ameliorating noise-induced hearing loss, we studied the auditory function, cochlear morphology, gene expression and oxidative stress markers in mice exposed to noise and treated with TGF-ß1 peptidic inhibitors P17 and P144, just before or immediately after noise insult. Our results indicate that systemic administration of both peptides significantly improved both the evolution of hearing thresholds and the degenerative changes induced by noise-exposure in lateral wall structures. Moreover, treatments ameliorated the inflammatory state and redox balance. These therapeutic effects were dose-dependent and more effective if the TGF-ß1 inhibitors were administered prior to inducing the injury. In conclusion, inhibition of TGF-ß1 actions with antagonistic peptides represents a new, promising therapeutic strategy for the prevention and repair of noise-induced cochlear damage.

Rosenberg, T; Haim, M; Hauch, A M; Parving, A

1997-05-01

The study was undertaken to procure population-based prevalence data on the various types of Usher syndrome and other retinal dystrophy-hearing impairment associations. The medical files on 646 patients with a panretinal pigmentary dystrophy aged 20-49 years derived from the Danish Retinitis Pigmentosa (RP) register were scrutinised. The data were supplemented by a prior investigation on hearing ability in a part of the study population. After exclusion of patients with possibly extrinsic causes of hearing impairments, 118 patients, including 89 cases of Usher syndrome were allocated to one of five clinically defined groups. We calculated the following prevalence rates: Usher syndrome type I: 1.5/100,000, Usher syndrome type II: 2.2/100,000, and Usher syndrome type III: 0.1/100,000 corresponding to a 2:3 ratio between Usher syndrome type I and II. The overall prevalence rate of Usher syndrome was estimated to 5/100,000 in the Danish population, devoid of genetic isolates. The material comprised 11 cases with retinal dystrophy, hearing impairment, and additional syndromic features. Finally, 18 subjects with various retinal dystrophy-hearing impairment associations without syndromic features were identified, corresponding to a prevalence rate of 0.8/100,000. This group had a significant overrepresentation of X-linked RP, including two persons harboring a mutation in the retinitis pigmentosa GTP-ase regulator (RPGR) gene.

Full Text Available Individuals with hearing impairment are confronted with a lot of problems due to the condition of their disability. This has a negative impact on their social and psychological well-being with multiplying effect on their interpersonal relationship. Therefore, this study investigated the psycho-social influence of hearing impairment on interpersonal behavior of youths with hearing loss.MethodologyThe study adopted a survey research design. A sample consisting of 211 participants with hearing loss were purposively selected from the Federal College of Education (Special Oyo, Nigeria. A questionnaire, part of Psycho-social Competence Scale (PCS, was used for data collection with reliability coefficient of 0.72.ResultsThe findings revealed that hearing impairement affects social interaction of youths with hearing impairment, hearing loss affects emotional well-being of youths with hearing impairment and youths with hearing impairment feel inferior in company of persons without hearing impairment. Based on this, it was recommended that a friendly home environment should be made and youths with hearing impairment should be advised to accept their loss and take it as a challenge that can be used to achieve a better end and the society should have right attitude and beliefs toward youths with hearing impairment.

This study explored the psychosocial experiences of adults with hearing loss using the self-regulatory model as a theoretical framework. The primary components of the model, namely cognitive representations, emotional representations, and coping responses, were examined. Individual semi-structured interviews were conducted. The data were analysed using an established thematic analysis procedure. Twenty-five adults with mild-moderate hearing loss from the UK and nine hearing healthcare professionals from the UK, USA, and Canada were recruited via maximum variation sampling. Cognitive representations: Most participants described their hearing loss as having negative connotations and consequences, although they were not particularly concerned about the progression or controllability/curability of the condition. Opinions differed regarding the benefits of understanding the causes of one's hearing loss in detail. Emotional representations: negative emotions dominated, although some experienced positive emotions or muted emotions. Coping responses: engaged coping (e.g. hearing aids, communication tactics) and disengaged coping (e.g. withdrawal from situations, withdrawal within situations): both had perceived advantages and disadvantages. This novel application of the self-regulatory model demonstrates that it can be used to capture the key psychosocial experiences (i.e. perceptions, emotions, and coping responses) of adults with mild-moderate hearing loss within a single, unifying framework.

Renal transplant provides a long-term survival. Hearing impairment is a major factor in subjective health status. Status of hearing and the cause of hearing impairment in the pediatric renal transplant group have not been evaluated. Here, we studied to evaluate hearing status in pediatric renal transplant patients and to determine the factors that cause hearing impairment. Twenty-seven pediatric renal transplant recipients were investigated. All patients underwent audiologic assessment by means of pure-tone audiometry. The factors on hearing impairment were performed. Sensorineural hearing impairment was found in 17 patients. There was marked hearing impairment for the higher frequencies between 4000 and 8000 Hz. Sudden hearing loss developed in 2 patients, 1 of them had tinnitus. Decrease of speech understanding was found in 8 patients. The cyclosporine level was significantly high in patients with hearing impairment compared with group without hearing impairment. Cyclosporine levels also were found to be statistically significantly high when compared with the group with decrease of speech understanding and the group without decrease of speech understanding. Similar relations cannot be found between tacrolimus levels and hearing impairment and speech understanding. Sensorineural hearing impairment prevalence was high in pediatric renal transplant recipients when compared with the general population of children. Cyclosporine may be responsible for causing hearing impairment after renal transplant. We suggest that this effect is a dose-dependent toxicity.

Full Text Available Background and Aim: Reading skill is one of the most important necessities of students' learning in everyday life. This skill is referred to the ability of comprehension, comment and conclusion from texts and receiving the meaning of the massage which is composed. Educational development in any student has a direct relation with the ability of the comprehension. This study is designed to investigate the effects of hearing loss on reading comprehension in hearing-impaired students compared to normal-hearing ones.Methods: Seventeen hearing-impaired students in 4th year of primary exceptional schools in Karaj, Robatkarim and Shahriyar, Iran, were enrolled in this cross-sectional study. Seventeen normal-hearing students were randomly selected from ordinary schools next to exceptional ones as control group. They were compared for different levels of reading comprehension using the international standard booklet (PIRLS 2001. Results: There was a significant difference in performance between hearing-impaired and normal- hearing students in different levels of reading comprehension (p<0.05.Conclusion: Hearing loss has negative effects on different levels of reading comprehension, so in exceptional centers, reconsideration in educational planning in order to direct education from memorizing to comprehension and deeper layers of learning seems necessary.

2005-01-01

The effect of acute low-tone sensorineural hearing loss (ALHL) on the interaural frequency difference (IFD) required for perception of binaural beats (BBs) was investigated in 12 patients with unilateral ALHL and 7 patients in whom ALHL had lessened. A continuous pure tone of 30 dB sensation level at 250 Hz was presented to the contralateral, normal-hearing ear. The presence of BBs was determined by a subjective yes-no procedure as the frequency of a loudness-balanced test tone was gradually adjusted around 250 Hz in the affected ear. The frequency range in which no BBs were perceived (FRNB) was significantly wider in the patients with ALHL than in the controls, and FRNBs became narrower in the recovered ALHL group. Specifically, detection of slow BBs with a small IFD was impaired in this limited (10 s) observation period. The significant correlation between the hearing level at 250 Hz and FRNBs suggests that FRNBs represent the degree of cochlear damage caused by ALHL.

Occupational noise injury and hearing loss are common features of agricultural workforces internationally. Farmsafe Australia has identified hearing health as one of its 4 key priority goals and targets. Currently, approximately 60-70% of Australian farmers have measurable hearing loss, compared with 27% of those in the general Australian community. This article describes the findings of a community based demonstration project to address hearing health issues conducted in the Australian state of New South Wales. This program sought to implement local demonstration projects in 3 communities to identify what works well in hearing health promotion with farmers and what could be applied more broadly throughout Australia. Local advisory groups were established in each community to guide project development and implementation. Project implementation focused on 3 major aspects: (1) increasing awareness of priority noise injury prevention and hearing health practices; (2) improving access to hearing health services; and (3) networking services in local communities. Area-specific training was undertaken for stakeholders to maximize local information links. Service utilization data were monitored and analysed. There was variability among sites; however in general there was an increased awareness of hearing health issues by farming families and expanded opportunities for farmers to access screening services. Utilization rates of hearing services also increased markedly in one community. Local hearing health networks were strengthened by linkages to key stakeholders outside the health sector. Previously unidentified methods of promoting hearing health (eg using agricultural retail outlets that supply hearing protection equipment and are accepted by farmers as an information source) were identified and utilized. Hearing health promotion with farmers in local communities can be enhanced through utilization and strengthening of local networks. Integration of hearing health

Newborn hearing screening.

Congenital deafness is a relatively common problem with an incidence of 1/300 to 1/1000. Most states have no mass screening program for hearing loss, but the state of Kentucky compiles a High Risk Registry which is a historical survey of parents relating to risk factors for hearing loss. Unfortunately this survey can miss 50% of those who have a hearing deficit. If not detected prior to discharge, there is often a delay in diagnosis of deafness which prevents early intervention. We report 2 years' experience at Kosair Children's Hospital where 1,987 infants admitted to well baby, intermediate, or intensive care nurseries were screened using the ALGO-1 screener (Natus Medical Inc, Foster City, CA) which is a modified auditory brain stem evoked response (ABR). Our screening of this population led to an 11% incidence of referral for complete audiological evaluation. There were no significant complications. Forty-eight infants were found to have nonspecified, sensorineural, or conductive hearing loss. The positive predictive value of the test was 96%. Therefore, we feel that the use of the modified ABR in the newborn is a timely, cost efficient method of screening for hearing loss and should be used for mass screening of all newborns.

Hearing Preservation in Cochlear Implant Surgery

Directory of Open Access Journals (Sweden)

Priscila Carvalho Miranda

2014-01-01

Full Text Available In the past, it was thought that hearing loss patients with residual low-frequency hearing would not be good candidates for cochlear implantation since insertion was expected to induce inner ear trauma. Recent advances in electrode design and surgical techniques have made the preservation of residual low-frequency hearing achievable and desirable. The importance of preserving residual low-frequency hearing cannot be underestimated in light of the added benefit of hearing in noisy atmospheres and in music quality. The concept of electrical and acoustic stimulation involves electrically stimulating the nonfunctional, high-frequency region of the cochlea with a cochlear implant and applying a hearing aid in the low-frequency range. The principle of preserving low-frequency hearing by a “soft surgery” cochlear implantation could also be useful to the population of children who might profit from regenerative hair cell therapy in the future. Main aspects of low-frequency hearing preservation surgery are discussed in this review: its brief history, electrode design, principles and advantages of electric-acoustic stimulation, surgical technique, and further implications of this new treatment possibility for hearing impaired patients.

Ruesch, Amy L

2018-01-01

Poor communication between the Registered Nurse and a hearing impaired patient can affect quality of care and health outcomes. Communication skills training programs for healthcare providers are needed to improve patient centered care. A descriptive research study, using a knowledge assessment tool developed and validated by the researcher, was conducted on 339 Registered Nurses to identify knowledge deficits to be addressed in a communication skills training program being designed. The educational tool measured the Registered Nurses' knowledge across four areas - hearing impairment, hearing aids, communication strategies, and regulations regarding access to care for a person with a hearing disability. Knowledge deficits were detected in all four areas. Using this educational assessment tool may enable nurse educators to tailor communication skills training programs to specifically address the gaps identified regarding hearing impairment and how to effectively communicate with the hearing impaired patient. Post training program, nurse educators can use the tool to evaluate effectiveness. Copyright © 2017 Elsevier Ltd. All rights reserved.

The relationship between high-frequency pure-tone hearing loss, hearing in noise test (HINT) thresholds, and the articulation index.

Science.gov (United States)

Vermiglio, Andrew J; Soli, Sigfrid D; Freed, Daniel J; Fisher, Laurel M

2012-01-01

Speech recognition in noise testing has been conducted at least since the 1940s (Dickson et al, 1946). The ability to recognize speech in noise is a distinct function of the auditory system (Plomp, 1978). According to Kochkin (2002), difficulty recognizing speech in noise is the primary complaint of hearing aid users. However, speech recognition in noise testing has not found widespread use in the field of audiology (Mueller, 2003; Strom, 2003; Tannenbaum and Rosenfeld, 1996). The audiogram has been used as the "gold standard" for hearing ability. However, the audiogram is a poor indicator of speech recognition in noise ability. This study investigates the relationship between pure-tone thresholds, the articulation index, and the ability to recognize speech in quiet and in noise. Pure-tone thresholds were measured for audiometric frequencies 250-6000 Hz. Pure-tone threshold groups were created. These included a normal threshold group and slight, mild, severe, and profound high-frequency pure-tone threshold groups. Speech recognition thresholds in quiet and in noise were obtained using the Hearing in Noise Test (HINT) (Nilsson et al, 1994; Vermiglio, 2008). The articulation index was determined by using Pavlovic's method with pure-tone thresholds (Pavlovic, 1989, 1991). Two hundred seventy-eight participants were tested. All participants were native speakers of American English. Sixty-three of the original participants were removed in order to create groups of participants with normal low-frequency pure-tone thresholds and relatively symmetrical high-frequency pure-tone threshold groups. The final set of 215 participants had a mean age of 33 yr with a range of 17-59 yr. Pure-tone threshold data were collected using the Hughson-Weslake procedure. Speech recognition data were collected using a Windows-based HINT software system. Statistical analyses were conducted using descriptive, correlational, and multivariate analysis of covariance (MANCOVA) statistics. The

Symphony orchestra musicians′ use of hearing protection and attenuation of custom-made hearing protectors as measured with two different real-ear attenuation at threshold methods

Directory of Open Access Journals (Sweden)

K H Huttunen

2011-01-01

Full Text Available Despite a high level of sound exposure and a fairly large selection of earplugs available, musicians have often been reported to use personal hearing protectors only seldom. For better hearing conservation, it is important to identify and eliminate the causes for the low motivation to use hearing protection. We explored the usage rate of custom-molded musician′s earplugs (ER-15 among 15 symphony orchestra musicians with a questionnaire, and measured the attenuation properties of their earplugs with a Real-Ear Attenuation at Threshold (REAT procedure in a sound field. Earplug use was found to be low, and the musicians reported that earplugs hampered listening to their own and their colleagues′ playing; earplugs affected either timbre or dynamics, or both. Additionally, several reasons related to discomfort of use were itemized, but the musicians who consistently used their earplugs did so in spite of problems with use. The REAT values obtained in sound field were relatively close to the manufacturer′s nominal specifications, being 13.7 dB, on average. In the frequency range studied (0.125-8 kHz, individual variation in REAT was, however, up to 15 dB across the measured frequencies. Fluctuation in attenuation might be related to low use of hearing protectors, and REAT measured at fixed center frequencies may be too robust a method to uncover it. We therefore tested 10 additional subjects to find out whether a sweeping signal used in Bιkιsy audiometry would bring more detailed information on earplug attenuation. Mean attenuation was found to be somewhat closer to the nominal attenuation of the ER-9 and ER-15 earplugs up to about 1 kHz, whereas REAT measurements in sound field revealed more even attenuation at frequencies between 1 and 6 kHz. No significant association was found between earplug attenuation properties and earplug use. It was concluded that support and determination to get accustomed to hearing protector use are important

Full Text Available Hearing loss is the third most common condition affecting adults over 65 (Cruickshanks et al., 1998. It can affect quality of life, limiting the ability to communicate efficiently, and leading to isolation, psychological strain, and functional decline (LaForge, Spector, Sternberg, 1992; Yueh, Shapiro, MacLean, Shekelle, 2003. Communication limitations impinge on the person directly, as well as the family, friends, and social circle. Reports on hearing loss among adults indicate that less than 25% of people who can benefit from amplification are actually using hearing aids, and that people diagnosed with a hearing loss delay seeking amplification by about seven years (Kochkin, 1997. Often, family members are the driving force behind a person with a hearing loss who decides to seek help. Adult hearing screening programs might have a positive effect on raising public awareness on hearing loss and its implications, and shortening delay time for intervention. There is no routine hearing screening for the adult population in Cyprus. The health system provides hearing tests for beneficiaries upon physician recommendation or self-referral.

Nuclear regulation in the 1980s - a leadership role

International Nuclear Information System (INIS)

Asselstine, J.K.

1983-01-01

An overview of cooperation between the Nuclear Regulatory Commission (NRC) and the nuclear industry cites the Institute of Nuclear Power Operations (INPO) as a model for other cooperative efforts, both in determining the need for and the appropriateness of regulatory requirements. The author addresses three needs of nuclear regulation that will be significant during the 1980s: to adapt our regulatory program to a changing workload; to address safety issues, and particularly the development of new safety requirements, for nuclear plants; and to modernize and improve the licensing process. Steps to improve licensing procedures could include standardization, the resolution of design issues before the start of construction, redefinition of the hearing process, limitations of later modifications, stable commission decision making authority, and recognition of the commission's authority to consider economic costs in making regulatory decisions

Hearing loss is the second most common disability awarded by the U.S. Department of Veterans Affairs (VA) to former members of the U.S. uniformed services. Hearing readiness and conservation practices differ among the four largest uniformed military services (Air Force, Army, Marine Corps, and Navy). Utilizing a data set consisting of all hearing loss claims submitted to the VA from fiscal years 2003-2013, we examined characteristics of veterans submitting claims within one year of separation from military service. Our results indicate that having a hearing loss disability claim granted was significantly more likely for men, individuals over the age of 26 years at the time of the claim, individuals most recently serving in the U.S. Army, and those with at least one hearing loss diagnosis. Importantly, individuals with at least one test record in the Defense Occupational and Environmental Health Readiness System-Hearing Conservation (DOEHRS-HC) system were significantly less likely to have a hearing loss disability claim granted by the VA. Within the DOEHRS-HC cohort, those with at least one threshold shift or clinical hearing loss diagnosis while on active duty were more than two and three times more likely to have a hearing loss disability claim granted, respectively. These findings indicate that an established history of reduced hearing ability while on active duty was associated with a significantly increased likelihood of an approved hearing loss disability claim relative to VA claims without such a history. Further, our results show a persistent decreased rate of hearing loss disability awards overall. These findings support increased inclusion of personnel in DoD hearing readiness and conservation programs to reduce VA hearing loss disability awards. Copyright © 2016 Elsevier B.V.

2014-10-01

The Hybrid cochlear implant (CI), also known as Electro-Acoustic Stimulation (EAS), is a new type of CI that preserves residual acoustic hearing and enables combined cochlear implant and hearing aid use in the same ear. However, 30-55% of patients experience acoustic hearing loss within days to months after activation, suggesting that both surgical trauma and electrical stimulation may cause hearing loss. The goals of this study were to: 1) determine the contributions of both implantation surgery and EAS to hearing loss in a normal-hearing guinea pig model; 2) determine which cochlear structural changes are associated with hearing loss after surgery and EAS. Two groups of animals were implanted (n = 6 per group), with one group receiving chronic acoustic and electric stimulation for 10 weeks, and the other group receiving no direct acoustic or electric stimulation during this time frame. A third group (n = 6) was not implanted, but received chronic acoustic stimulation. Auditory brainstem response thresholds were followed over time at 1, 2, 6, and 16 kHz. At the end of the study, the following cochlear measures were quantified: hair cells, spiral ganglion neuron density, fibrous tissue density, and stria vascularis blood vessel density; the presence or absence of ossification around the electrode entry was also noted. After surgery, implanted animals experienced a range of 0-55 dB of threshold shifts in the vicinity of the electrode at 6 and 16 kHz. The degree of hearing loss was significantly correlated with reduced stria vascularis vessel density and with the presence of ossification, but not with hair cell counts, spiral ganglion neuron density, or fibrosis area. After 10 weeks of stimulation, 67% of implanted, stimulated animals had more than 10 dB of additional threshold shift at 1 kHz, compared to 17% of implanted, non-stimulated animals and 0% of non-implanted animals. This 1-kHz hearing loss was not associated with changes in any of the cochlear measures

Suppression of Tinnitus in a Patient with Unilateral Sudden Hearing Loss: A Case Report

Directory of Open Access Journals (Sweden)

Alessandra Fioretti

2012-01-01

Full Text Available We describe a case of a 67-year-old woman with severe disabling right-sided tinnitus, mild hyperacusis, and headache. The tinnitus was associated with sudden right hearing loss and vertigo, which occurred about 18 months before. Magnetic resonance imaging (MRI resulted in normal anatomical structures of the cochlea and of the cranial nerves showing a partial empty sella syndrome with suprasellar cistern hernia. Angio-MR revealed a bilateral contact between the anterior-inferior cerebellar artery (AICA and the acoustic-facial nerve with a potential neurovascular conflict. Surgery was considered unnecessary after further evaluations. The right ear was successfully treated with a combination device (hearing aid plus sound generator. Shortly after a standard fitting procedure, the patient reported a reduction of tinnitus, hyperacusis, and headache which completely disappeared at the follow-up evaluation after 3, 6, and 12 months. This paper demonstrates that the combination device resulted in a complete tinnitus and hyperacusis suppression in a patient with unilateral sensorineural sudden hearing loss. Our paper further supports the restoration of peripheral sensory input for the treatment of tinnitus associated with hearing loss in selected patients.

Objective This study explored the psychosocial experiences of adults with hearing loss using the self-regulatory model as a theoretical framework. The primary components of the model, namely cognitive representations, emotional representations, and coping responses, were examined. Design Individual semi-structured interviews were conducted. The data were analysed using an established thematic analysis procedure. Study sample Twenty-five adults with mild-moderate hearing loss from the UK and nine hearing healthcare professionals from the UK, USA, and Canada were recruited via maximum variation sampling. Results Cognitive representations: Most participants described their hearing loss as having negative connotations and consequences, although they were not particularly concerned about the progression or controllability/curability of the condition. Opinions differed regarding the benefits of understanding the causes of one’s hearing loss in detail. Emotional representations: negative emotions dominated, although some experienced positive emotions or muted emotions. Coping responses: engaged coping (e.g. hearing aids, communication tactics) and disengaged coping (e.g. withdrawal from situations, withdrawal within situations): both had perceived advantages and disadvantages. Conclusions This novel application of the self-regulatory model demonstrates that it can be used to capture the key psychosocial experiences (i.e. perceptions, emotions, and coping responses) of adults with mild-moderate hearing loss within a single, unifying framework.

An objective investigation is needed to verify the existence and severity of hearing impairments resulting from work-related, noise-induced hearing loss in arbitration of medicolegal aspects. We investigated the accuracy of multiple-frequency auditory steady-state responses (Mf-ASSRs) between subjects with sensorineural hearing loss (SNHL) with and without occupational noise exposure. Cross-sectional study. Tertiary referral medical centre. Pure-tone audiometry and Mf-ASSRs were recorded in 88 subjects (34 patients had occupational noise-induced hearing loss [NIHL], 36 patients had SNHL without noise exposure, and 18 volunteers were normal controls). Inter- and intragroup comparisons were made. A predicting equation was derived using multiple linear regression analysis. ASSRs and pure-tone thresholds (PTTs) showed a strong correlation for all subjects (r = .77 ≈ .94). The relationship is demonstrated by the equationThe differences between the ASSR and PTT were significantly higher for the NIHL group than for the subjects with non-noise-induced SNHL (p tool for objectively evaluating hearing thresholds. Predictive value may be lower in subjects with occupational hearing loss. Regardless of carrier frequencies, the severity of hearing loss affects the steady-state response. Moreover, the ASSR may assist in detecting noise-induced injury of the auditory pathway. A multiple linear regression equation to accurately predict thresholds was shown that takes into consideration all effect factors.

Disrupted bone remodeling leads to cochlear overgrowth and hearing loss in a mouse model of fibrous dysplasia.

Directory of Open Access Journals (Sweden)

Omar Akil

Full Text Available Normal hearing requires exquisite cooperation between bony and sensorineural structures within the cochlea. For example, the inner ear secretes proteins such as osteoprotegrin (OPG that can prevent cochlear bone remodeling. Accordingly, diseases that affect bone regulation can also result in hearing loss. Patients with fibrous dysplasia develop trabecular bone overgrowth resulting in hearing loss if the lesions affect the temporal bones. Unfortunately, the mechanisms responsible for this hearing loss, which could be sensorineural and/or conductive, remain unclear. In this study, we used a unique transgenic mouse model of increased Gs G-protein coupled receptor (GPCR signaling induced by expression of an engineered receptor, Rs1, in osteoblastic cells. These ColI(2.3+/Rs1+ mice showed dramatic bone lesions that histologically and radiologically resembled fibrous dysplasia. We found that ColI(2.3+/Rs1+ mice showed progressive and severe conductive hearing loss. Ossicular chain impingement increased with the size and number of dysplastic lesions. While sensorineural structures were unaffected, ColI(2.3+/Rs1+ cochleae had abnormally high osteoclast activity, together with elevated tartrate resistant acid phosphatase (TRAP activity and receptor activator of nuclear factor kappa-B ligand (Rankl mRNA expression. ColI(2.3+/Rs1+ cochleae also showed decreased expression of Sclerostin (Sost, an antagonist of the Wnt signaling pathway that normally increases bone formation. The osteocyte canalicular networks of ColI(2.3+/Rs1+ cochleae were disrupted and showed abnormal osteocyte morphology. The osteocytes in the ColI(2.3+/Rs1+ cochleae showed increased expression of matrix metalloproteinase 13 (MMP-13 and TRAP, both of which can support osteocyte-mediated peri-lacunar remodeling. Thus, while the ossicular chain impingement is sufficient to account for the progressive hearing loss in fibrous dysplasia, the deregulation of bone remodeling extends to the

Narrative competence among hearing-impaired and normal-hearing children: analytical cross-sectional study

Directory of Open Access Journals (Sweden)

Alexandra Dezani Soares

Full Text Available CONTEXT AND OBJECTIVE: Oral narrative is a means of language development assessment. However, standardized data for deaf patients are scarce. The aim here was to compare the use of narrative competence between hearing-impaired and normal-hearing children. DESIGN AND SETTING: Analytical cross-sectional study at the Department of Speech-Language and Hearing Sciences, Universidade Federal de São Paulo. METHODS: Twenty-one moderately to profoundly bilaterally hearing-impaired children (cases and 21 normal-hearing children without language abnormalities (controls, matched according to sex, age, schooling level and school type, were studied. A board showing pictures in a temporally logical sequence was presented to each child, to elicit a narrative, and the child's performance relating to narrative structure and cohesion was measured. The frequencies of variables, their associations (Mann-Whitney test and their 95% confidence intervals was analyzed. RESULTS: The deaf subjects showed poorer performance regarding narrative structure, use of connectives, cohesion measurements and general punctuation (P < 0.05. There were no differences in the number of propositions elaborated or in referent specification between the two groups. The deaf children produced a higher proportion of orientation-related propositions (P = 0.001 and lower proportions of propositions relating to complicating actions (P = 0.015 and character reactions (P = 0.005. CONCLUSION: Hearing-impaired children have abnormalities in different aspects of language, involving form, content and use, in relation to their normal-hearing peers. Narrative competence was also associated with the children's ages and the school type.
