Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Speech Processing in the Auditory System written by Steven Greenberg and published by Springer Science & Business Media. This book was released on 2006-05-09 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although speech is the primary behavioral medium by which humans communicate, its auditory basis is poorly understood, having profound implications on efforts to ameliorate the behavioral consequences of hearing impairment and on the development of robust algorithms for computer speech recognition. In this volume, the authors provide an up-to-date synthesis of recent research in the area of speech processing in the auditory system, bringing together a diverse range of scientists to present the subject from an interdisciplinary perspective. Of particular concern is the ability to understand speech in uncertain, potentially adverse acoustic environments, currently the bane of both hearing aid and speech recognition technology. There is increasing evidence that the perceptual stability characteristic of speech understanding is due, at least in part, to elegant transformations of the acoustic signal performed by auditory mechanisms. As a comprehensive review of speech's auditory basis, this book will interest physiologists, anatomists, psychologists, phoneticians, computer scientists, biomedical and electrical engineers, and clinicians.

Download or read book A Microscopic Model of Speech Recognition for Listeners with Normal and Impaired Hearing written by Tim Jürgens and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a microscopic model of human speech recognition (HSR), microscopic in a sense that first, the recognition of single phonemes rather than the recognition of whole sentences is modeled. Second, the particular spectro-temporal structure of speech is processed by an auditory model. This contrasts with other models of HSR, which usually use the spectral structure only. The model is capable of predicting phoneme recognition in normal-hearing (NH) listeners in noise along with important aspects of consonant recognition in quiet. Furthermore, this model is extended for the prediction of sentence recognition. The extension is capable of predicting speech recognition of NH and hearing-impaired (HI) listeners as accurately as a standard speech intelligibility model. Parameters reflecting the supra-threshold auditory processing are assessed in NH and HI listeners using psychoacoustical techniques such as forward masking and categorical loudness scaling. These supra-threshold auditory processing deficits are included in the model and the results show that implementing supra-threshold processing improves prediction accuracy. engl.

Download or read book The Handbook of Hearing and the Effects of Noise written by Karl D. Kryter and published by Brill Academic Pub. This book was released on 1994 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a comprehensive source of information on the fundamentals of hearing and sound physics. Using research from 1980 onward, this book is a critical review of past and up-to-date research findings and concepts on the effects of noise on people; it focuses on the psychological and physiological affects of noise on hearing and performance. This text elucidates the interrelations of the acoustical, physiological, psychological, and sociological factors that are involved in making noise a problem to individuals and societies. Also discussed are hearing loss, speech communications, annoyance, and health effects criteria for the limitation of exposures to noise in living and work areas. Key Features * Physical characteristics of sound and noise * Acoustical-sensorineural response characteristics of the ear * Basic psychological sensations and perceptions that ensue from analysis of sound and noise by the auditory system * Laboratory and real-life research on the impairments to hearing, speech communication, task performance, and mental and bodily health that occur from exposure to noise * Physical measures which predict adverse effects on hearing, behavior, and health from exposure to noise

Download or read book Listening to Speech written by Steven Greenberg and published by Psychology Press. This book was released on 2012-12-06 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human species is largely defined by its use of spoken language, so integral is speech communication to behavior and social interaction. Despite its importance in everyday life, comparatively little is known about the auditory mechanisms that underlie the ability to understand language. The current volume examines the perception and processing of speech from the perspective of the hearing system. The chapters in this book describe a comprehensive set of approaches to the scientific study of speech and hearing, ranging from anatomy and physiology, to psychophysics and perception, and computational modeling. The auditory basis of speech is examined within a biological and an evolutionary context, and its relevance to applied domains such as communication disorders and speech technology discussed in detail. This volume will be of interest to scientists, engineers, and clinicians whose professional work pertains to any aspect of spoken language or hearing science.

Download or read book Cochlear Hearing Loss written by Brian C. J. Moore and published by John Wiley & Sons. This book was released on 2007-09-27 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first edition was published in 1998, considerable advances have been made in the fields of pitch perception and speech perception. In addition, there have been major changes in the way that hearing aids work, and the features they offer. This book will provide an understanding of the changes in perception that take place when a person has cochlear hearing loss so the reader understands not only what does happen, but why it happens. It interrelates physiological and perceptual data and presents both this and basic concepts in an integrated manner. The goal is to convey an understanding of the perceptual changes associated with cochlear hearing loss, of the difficulties faced by the hearing-impaired person, and the limitations of current hearing aids.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three manuscripts presented here examine concepts related to speech perception in noise and ways to overcome poor speech intelligibility without depriving listeners of environmental sound recognition. Because of hearing-impaired (HI) listeners’ auditory deficits, there is a substantial need for speech-enhancement (noise reduction) technology. Recent advancements in deep learning have resulted in algorithms that significantly improve the intelligibility of speech in noise, but in order to be suitable for real-world applications such as hearing aids and cochlear implants, these algorithms must be causal, talker independent, corpus independent, and noise independent. Manuscript 1 involves human-subjects testing of a novel, time-domain-based algorithm that fulfills these fundamental requirements. Algorithm processing resulted in significant intelligibility improvements for both HI and normal-hearing (NH) listener groups in each signal-to-noise ratio (SNR) and noise type tested. In Manuscript 2, the range of speech-to-background ratios (SBRs) over which NH and HI listeners can accurately perform both speech and environmental recognition was determined. Separate groups of NH listeners were tested in conditions of selective and divided attention. A single group of HI listeners was tested in the divided attention experiment. Psychometric functions were generated for each listener group and task type. It was found that both NH and HI listeners are capable of high speech intelligibility and high environmental sound recognition over a range of speech-to-background ratios. The range and location of optimal speech-to-background ratios differed across NH and HI listeners. The optimal speech-to-background ratio also depended on the type of environmental sound present. Conventional deep-learning algorithms for speech enhancement target maximum intelligibly by removing as much noise as possible while maintaining the essential characteristics of the target speech signal. Manuscript 3 tests a new form of time-frequency masking that is designed to leave a small amount of background noise intact. The purpose of the unremoved background noise is to allow for environmental sound awareness while still providing significantly increased intelligibility. It was found that this type of processing resulted in significantly improved intelligibility and high environmental sound recognition performance for both types of listeners. It was also found that the same level of maximum attenuation provided the optimal balance of intelligibility and environmental sound recognition for both listener types.
