Modeling Sensorineural Hearing Loss

Book Description
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.
A Microscopic Model of Speech Recognition for Listeners with Normal and Impaired Hearing

Book Description
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.
Speech Processing in the Auditory System

Languages : en
Pages : 487
Book Description
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.
