Download or read book The Acoustic Reflex written by Shlomo Silman and published by Elsevier. This book was released on 2012-12-02 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Acoustic Reflex discusses the acoustic reflex - its magnitude in differential diagnosis, threshold, latency, and other related topics. The book covers different topics such as the neurophysiological basis of the acoustic middle-ear reflex and its characteristics; impedance concepts relating to it; and theories of middle-ear muscle function. The text also encompasses the evaluation of the response time of acoustic-immittance instruments; the contralateral acoustic-reflex threshold and its application for prediction of hearing loss; the magnitude and growth of the acoustic; the ipsilateral acoustic reflex; and the acoustic reflex latency. The monograph is recommended for clinicians and researchers in audiology, deaf education, hearing science, neurology, otolaryngology, physiology, and psychology. The book will also serve as a reference text in a course on impedance.

Book excerpt: BoldAbstract /bolduniderlineIntroduction/underline: As shown in previous studies (Borg, Nilsson, & Engström, 1983; Zakrisson, Borg, Liden & Nilsson, 1980) the absence of acoustic reflex (AR) increases the hearing hazards from noise exposure. Past researchers (Stach, 1987; Colletti & Sittoni, 1986; Stach & Jerger, 1984) have studied the AR as a potential indicator of individuals' susceptibility to noise. The Colletti & Sittoni (1986) study indicates a relationship between the strength of the acoustic reflex contraction and the ear's resistance to noise. However, no relationship has been established so far between the acoustic reflex characteristics and susceptibility to develop a noise-induced hearing loss.^The goal of this project is to evaluate whether the strength of contraction of the acoustic reflex in workers exposed to high level noise is correlated with their industrial acquired hearing loss.Method: Retrospective analysis was conducted on 82 workers exposed to noise environments (Leq) of approximately 90 dBA. Participants were divided into four groups according to their hearing threshold (HT) in relation to their predicted ISO 1999 distribution (predicted hearing threshold based on a normal distribution with a given age as well as time and level of exposure). Group 1 was composed of workers with excellent hearing (HT falling between the 75th and the 90th percentile of the ISO 1999 distribution), Group 2 with just above average hearing workers (HT between the 50th and the 75th percentile), and Group 3 with just below average hearing workers (HT between the 25th and the 50th percentile.^Group 4, on its side, was composed of workers that had developed the same amount of hearing loss as Group 2 workers but in a much shorter period of time (3 to 10 years in contrast to 13 to 20 years for Group 2 workers). All participants underwent an audiometric testing as well as an acoustic reflex measurement using a newly developed Interacoustic Wideband Reflectance instrument. Wideband acoustic reflexes were evaluated using 500, 1000 and 2000 Hz pure tones as well as a broad band noise. The acoustic reflex thresholds, strength of contraction as well as dynamic range were compared between the four groups for all stimulus presentations.Results: Observed results tend to show that Group 1 (more resistant to noise) has on average stronger acoustic reflex (lower acoustic reflex threshold, stronger contraction) than Group 4 (least resistant to noise).^However, due to a large inter-individual variability and relatively small number of subjects for a field study, the observed tendencies are not statistically significant. The need for further investigation to establish a correlation or a lack of correlation between AR and susceptibility to noise-induced hearing loss is clear. It would be of great interest to be able to prevent noise-induced hearing loss before it happens.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Hearing Science and Hearing Disorders focuses on the nature of the processes in the inner ear and the nervous system that mediate hearing. Organized into eight chapters, this book first discusses the nature of speech communication, the extent of hearing problems, and the pathophysiology of hearing. Four core chapters follow, in which four areas of central importance to understanding hearing disorders and their effects are covered. These areas are assessment of auditory function, the scope for technological solutions, the nature of audio-visual speech perception, and the effects of deafness upon speech production. This book will be valuable to students; to academic and professional workers concerned with hearing, speech, and their disorders; and to scientifically or medically literate people in general.
