Book excerpt: The most common type and configuration of hearing loss seen in clinics is high frequency sensorineural hearing loss. High-frequency hearing losses can lead to difficulties understanding speech in noise. Traditional amplification can aid in audibility of high-frequency information; however, its success is limited due to acoustic feedback, output limitations of the hearing aids, and loudness discomfort (Bohnert, Nyffeler, & Keilmann, 2010, Turner & Cummings, 1999). Cochlear dead regions further hinder the success of traditional hearing aids, as speech recognition may not improve with increased audibility (Turner & Cummings, 1999). Frequency-lowering algorithms, developed by four major hearing aid manufacturers, attempt to provide improved audibility and speech understanding. Several studies have assessed the success of this technology; however mixed results have been found. The current study's purpose is to examine the effects of adaptive frequency lowering on phoneme identification and sound quality of music. Seven subjects with high frequency hearing loss were fit with Starkey Xino RITE hearing aids and were tested in two conditions (adaptive frequency lowering on and adaptive frequency lowering off). The Nonsense Syllable Test, Speech Perception In Noise test, and sound quality of music forced choice protocol were used to compare the two algorithms. The results of this study revealed no significant differences between traditional amplification and adaptive frequency lowering algorithm for identification of nonsense syllables, speech perception in noise, and preference of sound quality of music.

Book Synopsis Hearing Loss by : National Research Council
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.

Book Synopsis Pediatric Amplification by : Ryan W. McCreery
Download or read book Pediatric Amplification written by Ryan W. McCreery and published by Plural Publishing. This book was released on 2017-06-30 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pediatric Amplification: Enhancing Auditory Access is a comprehensive resource that focuses specifically on the process of fitting children with hearing aids, a population that is underrepresented in the scientific and clinical literature. The text is based on a theoretical framework that posits that well-fit, consistently worn hearing aids can optimize the auditory access of children with hearing loss. This theoretical framework serves as the basis for providing clinical care to children with hearing aids and their families. The content is organized around using best practices to provide aided audibility, promote consistent hearing aid use, and engage in high-quality linguistic input for children who wear hearing aids. The text is unique in its focus on the clinical management of amplification in the pediatric population using cutting-edge research based on the needs of children who are hard of hearing. It includes chapters dedicated to hearing assistance technology and case studies to illustrate the concepts presented. Pediatric Amplification is a professional resource for clinicians and audiologists who serve children who wear hearing aids and their families and can also be used in graduate courses for students in audiology, deaf education, and speech-language pathology.

Book Synopsis Speech Processing in the Auditory System by : Steven Greenberg
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 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To date, the main focus in frequency lowering hearing aid studies has been in relation to speech perception abilities. With improvements in hearing aid technology, there is a growing interest in musical perception as a dimension that could improve hearing aid users' quality of life. The purpose of this study was two-fold: Firstly, to develop a test of music perception for adult hearing aid users and secondly, to evaluate the influence of non-linear frequency compression (NFC) on music perception with the use of the Music Perception Test (MPT) compiled by the researcher. Research design and research sample: Phase 1 entailed the compilation of the MPT and can be described as design-based. A quasi-experimental research design was selected to establish the structure of the method employed in Phase 2, which involved the fitting of participants (n=40) with NFC hearing aids. Objective data was obtained with the hearing aids with NFC active and inactive. Phase 3 was characterized by a survey design which elicited subjective impressions of the participants' musical experiences with NFC active and inactive. Results: Results proved that normal hearing adults as well as adults using hearing aids were able to complete all the sub-tests of the MPT. Furthermore, the use of NFC resulted in a statistically significant improvement in hearing aid users' perception of timbre and melody, but not of pitch. Overall, no statistically significant improvement in their perception of rhythm was observed, although their performance on some rhythm sub-tests improved significantly. The use of NFC also brought about a statistically significant improvement in hearing aid users' perception of the music qualities of overall fidelity, tinniness and reverberance. Although participants experienced the loudness, fullness, crispness, naturalness and pleasantness of music more positively with NFC, these benefits were not statistically significant. Conclusion: The MPT can be used successfully for assessing music perception in hearing aid users within the South African context and may therefore result in more accountable hearing aid fittings. The use of NFC may increase hearing aid users' appreciation of music whilst not influencing music perception negatively. Given that a large percentage of hearing aid users express a loss in enjoyment of music, audiologists should not ignore the possible benefits of NFC, especially if one takes into account that previous research indicated speech perception benefits with this technology.

Book Synopsis The Influence of Noise Type on Speech Recognition and Word Recall in Older and Hearing-impaired Listeners by : Brittney Carter
Download or read book The Influence of Noise Type on Speech Recognition and Word Recall in Older and Hearing-impaired Listeners written by Brittney Carter and published by . This book was released on 2020 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study used a dual-task paradigm to describe how noise type may interact with aging and hearing loss to impact speech recognition and listening effort. Three noise types with varying degrees of spectral and/or temporal modulation were used: speech-shaped noise, speech-modulated noise, and three-talker babble. Subject groups included young normal-hearing listeners, older listeners with near-normal hearing, and older listeners with sensorineural hearing loss. An adaptive measure was used to compare the SNR at which 70% sentence recognition was achieved in each noise type, allowing an analysis of the effects of age and hearing loss on the ability to benefit from spectro-temporal glimpsing. A word recall task was implemented in a dual-task paradigm to compare listening effort, while matching overall performance across noise types and subject groups. Results showed no evidence to support the hypothesis that noise type influenced listening effort in any subject group. Results also showed that younger normal-hearing listeners were highly robust to the detrimental effects of noise, while older listeners experienced reduction in listening effort when context was available. Sensorineural hearing loss nullified this benefit from context. This study presented novel findings regarding the effect of noise type on listening effort while overall speech recognition performance was controlled for.
