Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

This book was released on 1972 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enlisted submariners with high-frequency hearing loss (ave. of 22, 45 and 60 decibels at 3, 4 and 6 kiloHertz, respectively) performed poorer than a normal-hearing control group by 6.2 percentage points on rather easy tests of speech intelligibility, and by 5 percentage points on rather difficult tests containing speech in background noise. The performance of the hearing-loss group, however, for the easier tests exceeded by 12.7 points that of another normal-hearing control group in which the hearing loss was simulated by filtering. The hearing-loss subjects may be experience have compensated to some extent in easier situations for their defect. This was not true for the more difficult situations. (Author).

Download or read book Hearing Loss at 3 Kilohertz and the Chaba Proposed Clinical Test of Speech Discrimination in Noise written by C. K. Myers and published by . This book was released on 1972 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forty-eight young men, 21 with rather sharp audiometric losses above 2 kiloHertz, were given a standard test of monsyllables in noise. On the average, these 47 men scored 10 fewer words correct per 100 than has been reported for normal controls. Scattergrams of performance vs a variety of pure-tone and speech threshold data, however, showed that no audiometric information could predict performance in noise. It was concluded that the standardized speech-in-noise test itself should be considered as the predictor instead of threshold tests, and that it should be validated against actual job performance.

Download or read book Hereditary Hearing Loss and Its Syndromes written by Helga V. Toriello and published by Oxford University Press. This book was released on 2013-06-20 with total page 749 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third edition of the foremost medical reference on hereditary hearing loss. Chapters on epidemiology, embryology, non-syndromic hearing loss, and syndromic forms of hearing loss have all been updated with particular attention to the vast amount of new information on molecular mechanisms, and chapters on clinical and molecular diagnosis and on genetic susceptibility to ototoxic factors have been added. As in previous editions, the syndromes are grouped by system (visual, metabolic, cardiologic, neurologic, musculoskeletal, endocrine, etc.), with each chapter written by a recognized expert in the field. Written for practicing clinicians, this volume is an excellent reference for physicians, audiologists, and other professionals working with individuals with hearing loss and their families, and can also serve as a text for clinical training programs and for researchers in the hearing sciences.
Download or read book Speech Discrimination in Noise and Hearing Loss at 3000 Hertz written by Thomas Murry and published by . This book was released on 1972 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Navy personnel with normal hearing and with hearing losses at 3 kHz and above were evaluated on tests of speech discrimination in noise. Two tests were used, one previously designed for use in audiological clinics and one constructed at this laboratory with background noise similar to that found in the enginerooms of nuclear submarines. The results indicate that subjects with hearing losses at 3 kHz and above may score as much as 11 per cent more generally at least five per cent below normals for a speech discrimination task in noise. For the two types of noise used in these tests, there was little or no difference in the general trend of test results. The correlation coeffieients obtained between the pure tone audiometric findings and the speech discrimination task in noise were found to be nonsignificant for the most part. From these results, it appears that hearing loss at 3 kHz reduces one's ability to discriminate speech in noise but this reduction is minor.
Download or read book Occupational Noise Exposure written by Department of Health and Human Services and published by Createspace Independent Publishing Platform. This book was released on 2014-02-19 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Occupational Safety and Health Act of 1970, Congress declared that its purpose was to assure, so far as possible, safe and healthful working conditions for every working man and woman and to preserve our human resources. In this Act, the National Institute for Occupational Safety and Health (NIOSH) is charged with recommending occupational safety and health standards and describing exposure concentrations that are safe for various periods of employment-including but not limited to concentrations at which no worker will suffer diminished health, functional capacity, or life expectancy as a result of his or her work experience. By means of criteria documents, NIOSH communicates these recommended standards to regulatory agencies (including the Occupational Safety and Health Administration [OSHA]) and to others in the occupational safety and health community. Criteria documents provide the scientific basis for new occupational safety and health standards. These documents generally contain a critical review of the scientific and technical information available on the prevalence of hazards, the existence of safety and health risks, and the adequacy of control methods. In addition to transmitting these documents to the Department of Labor, NIOSH also distributes them to health professionals in academic institutions, industry, organized labor, public interest groups, and other government agencies. In 1972, NIOSH published Criteria for a Recommended Standard: Occupational Exposure to Noise, which provided the basis for a recommended standard to reduce the risk of developing permanent hearing loss as a result of occupational noise exposure [NIOSH 1972]. NIOSH has now evaluated the latest scientific information and has revised some of its previous recommendations. The 1998 recommendations go beyond attempting to conserve hearing by focusing on preventing occupational noise-induced hearing loss (NIHL). This criteria document reevaluates and reaffirms the recommended exposure limit (REL) for occupational noise exposure established by the National Institute for Occupational Safety and Health (NIOSH) in 1972. The REL is 85 decibels, A-weighted, as an 8-hr time-weighted average (85 dBA as an 8-hr TWA). Exposures at or above this level are hazardous. By incorporating the 4000-Hz audiometric frequency into the definition of hearing impairment in the risk assessment, NIOSH has found an 8% excess risk of developing occupational noise-induced hearing loss (NIHL) during a 40-year lifetime exposure at the 85-dBA REL. NIOSH has also found that scientific evidence supports the use of a 3-dB exchange rate for the calculation of TWA exposures to noise. The recommendations in this document go beyond attempts to conserve hearing by focusing on prevention of occupational NIHL. For workers whose noise exposures equal or exceed 85 dBA, NIOSH recommends a hearing loss prevention program (HLPP) that includes exposure assessment, engineering and administrative controls, proper use of hearing protectors, audiometric evaluation, education and motivation, recordkeeping, and program audits and evaluations. Audiometric evaluation is an important component of an HLPP. To provide early identification of workers with increasing hearing loss, NIOSH has revised the criterion for significant threshold shift to an increase of 15 dB in the hearing threshold level (HTL) at 500, 1000, 2000, 3000, 4000, or 6000 Hz in either ear, as determined by two consecutive tests. To permit timely intervention and prevent further hearing losses in workers whose HTLs have increased because of occupational noise exposure, NIOSH no longer recommends age correction on individual audiograms.

Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the relationships of speech discrimination measures obtained in quiet and in noise with various distortion indexes with a group of subjects with sensorineural hearing loss. The results indicated that the most important factors associated with speech intelligibility were the extent and configuration of the hearing loss. The inter-relationships among DL tests for frequency and intensity, linear range measures, age, and pure-tone thresholds were examined. Comparisons were made with normal-hearing listeners.

Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This handbook synthesizes and analyzes the growing knowledge base on life course health development (LCHD) from the prenatal period through emerging adulthood, with implications for clinical practice and public health. It presents LCHD as an innovative field with a sound theoretical framework for understanding wellness and disease from a lifespan perspective, replacing previous medical, biopsychosocial, and early genomic models of health. Interdisciplinary chapters discuss major health concerns (diabetes, obesity), important less-studied conditions (hearing, kidney health), and large-scale issues (nutrition, adversity) from a lifespan viewpoint. In addition, chapters address methodological approaches and challenges by analyzing existing measures, studies, and surveys. The book concludes with the editors’ research agenda that proposes priorities for future LCHD research and its application to health care practice and health policy. Topics featured in the Handbook include: The prenatal period and its effect on child obesity and metabolic outcomes. Pregnancy complications and their effect on women’s cardiovascular health. A multi-level approach for obesity prevention in children. Application of the LCHD framework to autism spectrum disorder. Socioeconomic disadvantage and its influence on health development across the lifespan. The importance of nutrition to optimal health development across the lifespan. The Handbook of Life Course Health Development is a must-have resource for researchers, clinicians/professionals, and graduate students in developmental psychology/science; maternal and child health; social work; health economics; educational policy and politics; and medical law as well as many interrelated subdisciplines in psychology, medicine, public health, mental health, education, social welfare, economics, sociology, and law.
