Hearing: An Introduction to Psychological and Physiological Acoustics is concerned with the physiology and psychophysics of audition. It aims to introduce the new student to the sciences of hearing and to rekindle the interests of the experienced reader. The book begins with an overview of the auditory system. This is followed by separate chapters on theories of hearing; the routes over which sound is conducted to the inner ear; the cochlear mechanism; the auditory nerve and pathways; and psychoacoustic methods. Subsequent chapters cover the theory of signal detection; how sensitivity for one sound is affected by the presence of another sound; loudness; pitch; aspects of binaural hearing; and speech perception. This book provides both an introduction and a broad overview of the field of hearing science for the advanced undergraduate student or the postgraduate student in such disciplines as audiology and psychology. It should be an extremely useful guide to these students, as well as to those researchers who wish to refresh their knowledge of the field beyond their areas of specialization.
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.
