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.

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.

Rehabilitation of the geriatric patient poses a unique set of challenges and conditions often not seen in younger patients, but which are common among older adults. This quick, practical resource helps physiatrists and other members of the rehabilitation team overcome these challenges, covering the wide range of topics necessary to provide the highest level of care to this rapidly increasing population. - Presents practical guidance on arthritis and joint replacement, polypharmacy and mobility, swallowing dysfunction, nutritional recommendations, psychiatric and cognitive disorders, assistive technology, and more. - Covers the physiologic changes and epidemiology of aging, osteoporosis and fragility fractures, fall prevention and intervention, and prevention of hospital-acquired deconditioning. - Consolidates today's available information on geriatric rehabilitation into one convenient resource.

This book deals with the ear as an acoustic instrument: as a piece of physical apparatus functioning for the reception of sounds from the outside, for conveying them inward to the auditory sense cells, and finally for producing a mechanical stimulation of these cells. Originally published in 1954. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The localization of small vascular lesions within the brain-stem is the focal point of this volume which correlates clinical examination, evoked potentials, brain-stem reflexes and imaging techniques in one overview. For the first time, a group of experts has been brought together to summarize the various methods for detecting functional disturbances of specialized structures, to correlate these findings with morphologic criteria (MRI) and, finally, to elaborate patterns of abnormal findings which are characteristic of small brain-stem lesions. You are thus informed about neuro-physiological techniques which are superior to imaging techniques in local brain-stem pathology.
