A thesis about nonlinearity in the cochlea. Outer Hair Cells in the Organ of Corti amplify sound waves in a nonlinear way. For instance, they produce combination tones that do not exist in the original sound wave.

The International Symposium on Hearing is a prestigious, triennial gathering where world-class scientists present and discuss the most recent advances in the field of human and animal hearing research. The 2015 edition will particularly focus on integrative approaches linking physiological, psychophysical and cognitive aspects of normal and impaired hearing. Like previous editions, the proceedings will contain about 50 chapters ranging from basic to applied research, and of interest to neuroscientists, psychologists, audiologists, engineers, otolaryngologists, and artificial intelligence researchers.

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 cochlea does not just pick up sound, it also produces sounds of low intensity called Otoacoustic Emissions (OAEs). Sounds produced by healthy ears – either spontaneously or in response to stimuli - allow researchers and clinicians to study hearing and cochlear function noninvasively in both animals and humans. This book presents the first serious review of the biological basis of these otoacoustic emissions.

A recent study indicates that 20 million people in the United States have significant sensorineural hearing loss. Approximately 95% of those people have partial losses, with varying degrees of residual hearing. These percentages are similar in other developed countries. What changes in the function of the cochlea or inner ear cause such losses? What does the world sound like to the 19 million people with residual hearing? How should we transform sounds to correct for the hearing loss and maximize restoration of normal hearing? Answers to such questions require detailed models of the way that sounds are processed by the nervous system, both for listeners with normal hearing and for those with sensorineural hearing loss. This book contains chapters describing the work of 25 different research groups. A great deal of research in recent years has been aimed at obtaining a better physiological description of the altered processes that cause sensorineural hearing loss and a better understanding of transformations that occur in the perception of those sounds that are sufficiently intense that they can still be heard. Efforts to understand these changes in function have lead to a better understanding of normal function as well. This research has been based on rigorous mathematical models, computer simulations of mechanical and physiological processes, and signal processing simulations of the altered perceptual experience of listeners with sensorineural hearing loss. This book provides examples of all these approaches to modeling sensorineural hearing loss and a summary of the latest research in the field.

Hearing: Anatomy, Physiology and Disorders of the Auditory System, Third Edition, provides detailed information about the anatomy and physiology of the entire auditory system and describes important aspects of disorders of the middle ear, the cochlea, and the nervous system in a comprehensive manner. It has become apparent that the function of the ear affects the function of the auditory nervous system, and that pathologies of the peripheral parts of the auditory system can affect the function of the nervous system, and vice versa. The classical separation of the auditory system in peripheral and central parts is therefore no longer valid. This book integrates descriptions of disorders of the ear and the nervous system and provides a comprehensive coverage of anatomy and physiology of the entire auditory system; it also introduces the role of neural plasticity in creating symptoms of diseases of hearing such as tinnitus, hyperacusis and phonophobia. A separate chapter discuses cochlear and auditory brainstem implants.

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. Sample Chapter(s).

The Springer Handbook of Auditory Research presents a series of comp- hensive and synthetic reviews of the fundamental topics in modern au- tory research.The volumes are aimed at all individuals with interests in hearing research including advanced graduate students, post-doctoral researchers, and clinical investigators.The volumes are intended to int- duce new investigators to important aspects of hearing science and to help established investigators to better understand the fundamental theories and data in ?elds of hearing that they may not normally follow closely. Each volume is intended to present a particular topic comprehensively, and each chapter will serve as a synthetic overview and guide to the lit- ature.As such the chapters present neither exhaustive data reviews nor original research that has not yet appeared in peer-reviewed journals.The volumes focus on topics that have developed a solid data and conceptual foundation rather than on those for which a literature is only beginning to develop. New research areas will be covered on a timely basis in the series as they begin to mature.
