Hearing Loss


Book Description

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.




Cochlear Mechanics


Book Description

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.




Cochlear Mechanics


Book Description

This special issue collects our current knowledge of the mechanical processing of acoustic signals by the cochlea and its containing structures. Many workers in diverse disciplines in otology use the facts from cochlear mechanics for the interpretation of their results. Presented here for the first time is the development of a three-dimensional mechanical model of the curved cochlea including fluid-structure couplings. An important approach for future cochlear modeling is shown by the provision of geometrical data for the input of three-dimensional finite element models by microtomographic imaging. A remarkable article tries to demonstrate a connection between outer hair cell mechanics and the complex phenomenon of tinnitus and will be of special interest for stress engineers. Owing to its strong interdisciplinarity, this issue is not only intended for biophysicists, ENT clinicians and audiologists but also for radiologists, biomechanical engineers and computer engineers.

Overcoming Deafness: The Story Of Hearing And Language


Book Description

Hearing is one of the most empowering of our senses; it enables us to work, socialise and communicate. It's hard to imagine living in a silent world, yet just 60 years ago this was the inevitable outcome for the majority of people with ear disease or language problems. Nowadays, virtually everybody can be helped to some extent and many cured. But how did we get here?This book tells the fascinating story of science and medicine's winning battle with deafness, covering all the hearing diseases and the progress of their treatment from the beginning of Ellis Douek's career in the 1950s to the present day. Unlike other books on hearing, this covers language disorders as well as the surgery of deafness; it is a book about human communication, discussing music and poetry as well as delving into the medical science.In our ageing population, hearing disorders are increasingly a part of everyday life; that they are almost always treatable should not be taken for granted. This book should be the first reference for anyone who has experienced hearing loss and would like to know more about hearing and language development, and for professionals in hearing science, medicine and allied fields of interest.




The Cochlea


Book Description

Knowledge about the structure and function of the inner ear is vital to an understanding of vertebrate hearing. This volume presents a detailed overview of the mammalian cochlea from its anatomy and physiology to its biophysics and biochemistry. The nine review chapters, written by internationally distinguished auditory researchers, provide a detailed and unified introduction to sound processing in the cochlea and the steps by which the ensuing signals are prepared for the central nervous system.




An Introduction to the Physiology of Hearing


Book Description

This book deals with the way that the auditory system processes acoustic signals.




Recent Developments In Auditory Mechanics: Proceedings Of The International Symposium


Book Description

The articles in this volume are the results of discussions among biophysicists, neurobiologists and mathematicians with research interests in auditory mechanics and signal processing. The topics covered include: mechanics and models of hearing organs; auditory periphery and its models; middle ear; traveling wave and cochlear amplifier; emissions; outer hair cell; electromotility; central auditory processing; auditory nerve responses; and hearing in non-mammals.




Introduction to Psychology


Book Description

This book is designed to help students organize their thinking about psychology at a conceptual level. The focus on behaviour and empiricism has produced a text that is better organized, has fewer chapters, and is somewhat shorter than many of the leading books. The beginning of each section includes learning objectives; throughout the body of each section are key terms in bold followed by their definitions in italics; key takeaways, and exercises and critical thinking activities end each section.
