Available in PDF, EPUB and Kindle. Book excerpt: Wind noise is problematic for hearing aid users who enjoy outdoor activities. Not only is it annoying, it can create distortion by overloading the microphone and masking signals that hearing aid users desire to hear. Some hearing aid manufacturers offer wind noise reduction in addition to general noise reduction (WNR + NR) for clinicians to manipulate in their software. This study compares objective and subjective measures of wind noise reduction as well as subjective measure of intelligibility obtained using various hearing aid manufacturers and noise reduction settings while HINT sentences were played in the presence of constantly generated wind. Significant differences in the subjective and objective amount of noise present and perceived speech intelligibility was found both between manufacturers and between noise reduction settings for each manufacturer. Subjectively, intelligibility and noisiness were positively correlated (r=0.74, p>.001); conditions that were perceived to be the most intelligible were the same conditions that were perceived to be the noisiest. The perception of intelligibility and noisiness depended on the interaction of hearing aid manufacturer and noise reduction setting (p.001, effect size=.77) for hearing aids with WN + NR and depended on both hearing aid manufacturer (p

Download or read book DFT-Domain Based Single-Microphone Noise Reduction for Speech Enhancement written by Richard C. Hendriks and published by Morgan & Claypool Publishers. This book was released on 2013-01-01 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: As speech processing devices like mobile phones, voice controlled devices, and hearing aids have increased in popularity, people expect them to work anywhere and at any time without user intervention. However, the presence of acoustical disturbances limits the use of these applications, degrades their performance, or causes the user difficulties in understanding the conversation or appreciating the device. A common way to reduce the effects of such disturbances is through the use of single-microphone noise reduction algorithms for speech enhancement. The field of single-microphone noise reduction for speech enhancement comprises a history of more than 30 years of research. In this survey, we wish to demonstrate the significant advances that have been made during the last decade in the field of discrete Fourier transform domain-based single-channel noise reduction for speech enhancement.Furthermore, our goal is to provide a concise description of a state-of-the-art speech enhancement system, and demonstrate the relative importance of the various building blocks of such a system. This allows the non-expert DSP practitioner to judge the relevance of each building block and to implement a close-to-optimal enhancement system for the particular application at hand.

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.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Listening in environments with different kinds of background noises is especially difficult for individuals who suffer from hearing loss. For this reason, most modern hearing aids contain noise reduction (NR) algorithms. It is known that individual preferences for the settings of these algorithms are very diverse. Therefore, research is conducted to find NR parameters that are important for determining the preference of a listener and to find out what aspects, other than speech intelligibility, influence this preference. An important theme in this work is the trade-off between noise attenuation and signal quality which is a delicate balance that presumably determines the success of individual fine tuning of NR settings. When removing more unwanted noise from a signal the signal quality is inevitably affected as signal distortions arise. In the first four chapters of this thesis we investigated the effect of NR on listening effort, and the effect of varying NR time constants and NR strength on listener preference. The individual trade-off was a supposed reason as to why preferences are so diverse. In the fifth chapter of this thesis we visualized this trade-off and indeed found that each individual has a different tolerance towards background noise and signal distortions. The main aim of this thesis was to aid in the adequate and efficient selection and fine tuning of the optimal NR algorithm in a hearing aid for each individual listener. All research chapters of this work have contributed to this overarching goal."--

Available in PDF, EPUB and Kindle. Book excerpt: The Institute of Medicine carried out a study mandated by Congress and sponsored by the Department of Veterans Affairs to provide an assessment of several issues related to noise-induced hearing loss and tinnitus associated with service in the Armed Forces since World War II. The resulting book, Noise and Military Service: Implications for Hearing Loss and Tinnitus, presents findings on the presence of hazardous noise in military settings, levels of noise exposure necessary to cause hearing loss or tinnitus, risk factors for noise-induced hearing loss and tinnitus, the timing of the effects of noise exposure on hearing, and the adequacy of military hearing conservation programs and audiometric testing. The book stresses the importance of conducting hearing tests (audiograms) at the beginning and end of military service for all military personnel and recommends several steps aimed at improving the military services' prevention of and surveillance for hearing loss and tinnitus. The book also identifies research needs, emphasizing topics specifically related to military service.
