Great advances have been made in understanding hearing in recent years. In particular, the mechanical function of the cochlea has become the focus of intense interest. This started in one direction, with the discovery of otoacoustic emissions in 1978, which required active mechanical amplification processes, as first postulated by Gold in 1948. Direct evidence for the role of this mechanism in sharpening-up the otherwise poor, basilar membrane tuning properties, was provided in 1982; and in 1983, motility was shown in outer hair cells. In parallel, an immense amount of work has been done on the electrophysiology of hair cells, following the first intracellular recordings in 1977. Over a longer time scale, models of basilar membrane motion have been developed and refined, and recently much effort has been put into incorporating active mechanisms and non-linear processes. It seemed an opportune time to bring together the leading workers in these various areas, to take stock of the whole field and to stimulate further progress. This book represents the proceedings of a NATO ARW on the Mechanics of Hearing held at the University of Keele, 3-8 July, 1988. The conception of the meeting owes much to earlier meetings held in Boston in 1985 (Peripheral Auditory Mechallisms, Eds. J.B. Allen, J.L.

Basic Mechanisms in Hearing is a collection of papers that discusses the function of the auditory system covering its ultrastructure, physiology, and the mechanism's connection with experimental psychology. Papers review the mechanics, morphology, and physiology of the cochlear, including the physiology of individual hair cells and their synapses. One paper examines the combined physiological and anatomical studies of stimulus coding in the mammalian auditory nervous system. The results of these studies pertain to the latency, frequency selectivity, and time pattern of responses to short tone bursts. Other research compare the cochlear nerve, behavioral, and psychophysical frequency selectivity which show that frequency selectivity of the auditory system occurs at the level of the cochlear nerve, becoming downgraded in end-organ deafness. Other papers discuss neural coding at higher levels such as the feature extraction in the auditory system of bats. Some papers also analyze the specialized hearing mechanisms in animals, for example, the echolocation of bats and in some insects, the function of the swimbladder in fish hearing, as well as the "invertebrate frequency analyzer" in the locust ear. Physiologists, neurophysiologists, neurobiologists, general medical practioners, and EENT specialists will find this collection valuable.

The field of cochlear mechanics has received an increasing interest over the last few decades. In the majority of these studies the researchers use linear systems analysis or linear approximations of the nonlinear (NL) systems. Even though it has been clear that the intact cochlea operates nonlinearly, lack of tools for proper nonlinear analysis, and widely available tools for linear analysis still lead to inefficient and possibly incorrect interpretation of the biophysics of the cochlea. An example is the presumption that a change in cochlear stiffness at hair cell level must account for the observed change in tuning (or frequency mapping) due to prestin application. Hypotheses like this need to be addressed in a tutorial that is lucid enough to analyze and explain basic differences. Cochlear Mechanics presents a useful and mathematically justified/justifiable approach in the main part of the text, an approach that will be elucidated with clear examples. The book will be useful to scientists in auditory neuroscience, as well as graduate students in biophysics/biomedical engineering.

The workshop brought together experts in genetics, molecular and cellular biology, physiology, engineering, physics, mathematics, audiology and medicine to present current work and to review the critical issues of inner ear function. A special emphasis of the workshop was on analytical model based studies. Experimentalists and theoreticians thus shared their points of view. The topics ranged from consideration of the hearing organ as a system to the study and modeling of individual auditory cells including molecular aspects of function. Some of the topics in the book are: motor proteins in hair cells; mechanical and electrical aspects of transduction by motor proteins; function of proteins in stereocilia of hair cells; production of acoustic force by stereocilia, mechanical properties of hair cells and the organ of Corti; mechanical vibration of the organ of Corti; wave propagation in tissue and fluids of the inner ear; sound amplification in the cochlea; critical oscillations; cochlear nonlinearity, and mechanisms for the production of otoacoustic emissions. This book will be invaluable to researchers and students in auditory science.

In contrast to the level of interest which is paid to the orga nization of meetings about the structure and function of the audi tory periphery, the central auditory system has received little attention in the last several years. However, much recent data accu mulated during this period has provided auditory physiologists with new ideas about the function of the central auditory system. The successful exploration of new anatomical tracing techniques (triti ated aminoacids, horseradish peroxidase, 2-deoxyglucose) together with the collection of electrophysiological data obtained with intra cellular and extracellular recordings from the receptors and neurones in the auditory pathway have considerably deepened our understanding of central auditory function. Particular interest was concentrated upon the development of the auditory system under normal conditions and in conditions ofaudi tory deprivation. Although, from the methodological point of view, the conditions of reversible auditory deprivation are complicated, promising new data appeared in this field. Similarly the specific ability of the auditory system to encode communication signals and speech sounds has been examined in many laboratories allover the world. A very fruitful method. based upon the results of electrical stimulation of cochlear nerve fibres in experimental animals, is the application of neuroprostheses in deaf patients. At the present time, the method still does not meet all requirements and many improvements will be necessary. Undoubtedly the exploration of the results of recent physiological experiments may help in the further improvement of neuroprostheses.

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.
