This book was released on 2014-03-12 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is concerned with changes in the perception of sound that are associated with hearing loss and aging. Hearing loss affects about 7% of the population in developed countries, and the proportion is increasing as the average age of the population increases. The audiogram is the most widely used diagnostic tool in audiology clinics around the world. The audiogram involves measuring the threshold for detecting sounds of different frequencies. Sometimes the audiogram is the only diagnostic tool that is used. However, hearing problems are not completely characterized by the audiogram. Two individuals with similar audiograms may show very different abilities in the detection and discrimination of sounds at above-threshold levels. Also, a person may have hearing difficulties despite having an audiogram that is within the range conventionally considered as ‘normal’. One factor that may influence the discrimination of sounds, especially the ability to understand speech in background sounds, is sensitivity to temporal fine structure (TFS).This monograph reviews the role played by TFS in masking, pitch perception, speech perception, and spatial hearing, and concludes that cues derived from TFS play an important role in all of these. Evidence is reviewed suggesting that cochlear hearing loss reduces the ability to use TFS cues. Also, the ability to use TFS declines with increasing age even when the audiogram remains normal. This provides a new dimension to the changes in hearing associated with aging, a topic that is currently of great interest in view of the increasing proportion of older people in the population.The study of the role of TFS in auditory processing has been a hot topic in recent years. While there have been many research papers on this topic in specialized journals, there has been no overall review that pulls together the different research findings and presents and interprets them within a coherent framework. This monograph fills this gap.

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.

Download or read book How and Why Does Spatial Hearing Ability Differ among Listeners What Is the Role of Learning and Multisensory Interactions written by Guillaume Andéol and published by Frontiers Media SA. This book was released on 2016-08-29 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial-hearing ability has been found to vary widely across listeners. A survey of the existing auditory-space perception literature suggests that three main types of factors may account for this variability: - physical factors, e.g., acoustical characteristics related to sound-localization cues, - perceptual factors, e.g., sensory/cognitive processing, perceptual learning, multisensory interactions, - and methodological factors, e.g., differences in stimulus presentation methods across studies. However, the extent to which these–and perhaps other, still unidentified—factors actually contribute to the observed variability in spatial hearing across individuals with normal hearing or within special populations (e.g., hearing-impaired listeners) remains largely unknown. Likewise, the role of perceptual learning and multisensory interactions in the emergence of a multimodal but unified representation of “auditory space,” is still an active topic of research. A better characterization and understanding of the determinants of inter-individual variability in spatial hearing, and of its relationship with perceptual learning and multisensory interactions, would have numerous benefits. In particular, it would enhance the design of rehabilitative devices and of human-machine interfaces involving auditory, or multimodal space perception, such as virtual auditory/multimodal displays in aeronautics, or navigational aids for the visually impaired. For this Research Topic, we have considered manuscripts that: - present new methods, or review existing methods, for the study of inter-individual differences; - present new data (or review existing) data, concerning acoustical features relevant for explaining inter-individual differences in sound-localization performance; - present new (or review existing) psychophysical or neurophysiological findings concerning spatial hearing and/or auditory perceptual learning, and/or multisensory interactions in humans (normal or impaired, young or older listeners) or other species; - discuss the influence of inter-individual differences on the design and use of assistive listening devices (rehabilitation) or human-machine interfaces involving spatial hearing or multimodal perception of space (ergonomy).

Download or read book Hearing Aids written by Gerald R. Popelka and published by Springer. This book was released on 2016-09-26 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume will serve as the first Handbook of its kind in the area of hearing aid research, often the least-defined, least-understood, part of the multi-disciplinary research process. Most scientific training is very advanced within the particular disciplines but provides little opportunity for systematic introduction to the issues and obstacles that prevent effective hearing-aid related research. This area has emerged as one of critical importance, as signified by a single specialized meeting (the International Hearing Aid Conference, IHCON) that brings together specialists from the disparate disciplines involved, including both university and industry researchers. Identification of the key steps that enable high-impact basic science to ultimately result in significant clinical advances that improve patient outcome is critical. This volume will provide an overview of current key issues in hearing aid research from the perspective of many different disciplines, not only from the perspective of the key funding agencies, but also from the scientists and clinicians who are currently involved in hearing aid research. It will offer insight into the experience, current technology and future technology that can help improve hearing aids, as scientists and clinicians typically have little or no formal training over the whole range of the individual disciplines that are relevant. The selection and coverage of topics insures that it will have lasting impact, well beyond immediate, short-term, or parochial concerns. ​

Download or read book The effect of hearing loss on neural processing written by Jonathan E. Peelle and published by Frontiers Media SA. This book was released on 2015-06-03 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient auditory processing requires the rapid integration of transient sensory inputs. This is exemplified in human speech perception, in which long stretches of a complex acoustic signal are typically processed accurately and essentially in real-time. Spoken language thus presents listeners’ auditory systems with a considerable challenge even when acoustic input is clear. However, auditory processing ability is frequently compromised due to congenital or acquired hearing loss, or altered through background noise or assistive devices such as cochlear implants. How does loss of sensory fidelity impact neural processing, efficiency, and health? How does this ultimately influence behavior? This Research Topic explores the neural consequences of hearing loss, including basic processing carried out in the auditory periphery, computations in subcortical nuclei and primary auditory cortex, and higher-level cognitive processes such as those involved in human speech perception. By pulling together data from a variety of disciplines and perspectives, we gain a more complete picture of the acute and chronic consequences of hearing loss for neural functioning.

Download or read book Binaural Hearing written by Ruth Y. Litovsky and published by Springer Nature. This book was released on 2021-03-01 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of Binaural Hearing involves studies of auditory perception, physiology, and modeling, including normal and abnormal aspects of the system. Binaural processes involved in both sound localization and speech unmasking have gained a broader interest and have received growing attention in the published literature. The field has undergone some significant changes. There is now a much richer understanding of the many aspects that comprising binaural processing, its role in development, and in success and limitations of hearing-aid and cochlear-implant users. The goal of this volume is to provide an up-to-date reference on the developments and novel ideas in the field of binaural hearing. The primary readership for the volume is expected to be academic specialists in the diverse fields that connect with psychoacoustics, neuroscience, engineering, psychology, audiology, and cochlear implants. This volume will serve as an important resource by way of introduction to the field, in particular for graduate students, postdoctoral scholars, the faculty who train them and clinicians.

Download or read book Perception and Cognition Interactions in the Aging Brain written by Harriet A. Allen and published by Frontiers Media SA. This book was released on 2016-09-13 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Healthy ageing can lead to declines in both perceptual and cognitive functions. Impaired perception, such as that resulting from hearing loss or reduced visual or tactile resolution, increases demands on ‘higher-level’ cognitive functions to cope or compensate. It is possible, for example, to use focused attention to overcome perceptual limitations. Unfortunately, cognitive functions also decline in old age. This can mean that perceptual impairments are exacerbated by cognitive decline, and vice versa, but also means that interventions aimed at one type of decline can lead to improvements in the other. Just as improved cognition can ameliorate perceptual deficits, improving the stimulus can help offset cognitive deficits. For example, making directions and routes easy to follow can help compensate for declines in navigation abilities. In this Topic, we bring together papers from both auditory and visual researchers that address the interaction between perception and cognition in the ageing brain. Many of the studies demonstrate that a broadening of representations or increased reliance on gist underlie perceptual and cognitive age-related declines. There is also clear evidence that impaired perception is associated with poor cognition although, encouragingly, it can also be seen that good perception is associated with better cognition. Compensatory cognitive strategies were less successful in improving perception than might be expected. We also present papers which highlight important methodological considerations that are required when studying the older brain.

Download or read book Aging and Hearing written by Karen S. Helfer and published by Springer Nature. This book was released on 2020-10-20 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first edition of the Aging Auditory System volume (in 2009), there has been a tremendous amount of research in basic, translational, and clinical sciences related to age-related changes in auditory system structure and function. The new research has been driven by technical and conceptual advances in auditory neuroscience at multiple levels ranging from cells to cognition. The chapters in Aging and Hearing: Causes and Consequences span a broad range of topics and appeal to a relatively wide audience. Our goal in this volume is to put together state-of-the-art discussions about new developments in aging research that will appeal to a broad audience, serving as an important update on the current state of research on the aging auditory system. This update includes not only the recent research, but also consideration of how human and animal studies or translational and basic research are working in tandem to advance the field. This new edition is a natural complement to the previous SHAR volume on the aging auditory system edited by Gordon-Salant, Frisina, Popper, and Fay. The target audience for this volume will be graduate students, researchers, and academic faculty from a range of disciplines (psychology, hearing science/audiology, physiology, neuroscience, engineering). It also will appeal to clinical audiologists as well as to researchers working in the hearing device industry. Individuals who attend conferences sponsored by the Association for Research in Otolaryngology, Acoustical Society of America, Auditory Cognitive Neuroscience Society, American Auditory Society, Society for Neuroscience, American Speech, Language and Hearing Association, and the American Academy of Audiology (among others) are likely to find value in the volume.

Download or read book Listening with Two Ears New Insights and Perspectives in Binaural Research written by Huiming Zhang and published by Frontiers Media SA. This book was released on 2023-11-27 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hearing is dependent on neural processing of acoustic cues obtained by the left and right ears. Neural signals driven by the two ears are integrated at multiple levels of the central auditory system, which enables animals including humans to perform various functions including localization of a sound source. A natural listening environment typically contains sounds from multiple sources. These sounds can have different spectral and temporal features and occur at either the same or different time. Integration can happen among neural signals elicited by the same or different sounds. The way of integration can greatly affect how individual sounds are sensed and perceived. Functions such as auditory grouping and stream segregation, which are central to establishing coherent auditory images in a complex listening environment, are highly dependent on the way of integration. Binaural hearing is complicated by individual differences and developmental changes in head and pinna shape/size as binaural cues can be affected by these differences and changes. Furthermore, neural processing of binaural cues can be influenced by hearing impairments and the use of hearing aids and cochlear implants. These factors likely require a listener to optimize the use of binaural cues through learning and to use plastic changes in the nervous system to perform the optimization. Great strides have been made in understanding binaural processing in normal and impaired auditory systems. This Research Topic aims to highlight some of the latest findings in the following areas: 1) Animal behavioral and human psychoacoustical studies of binaural hearing; 2) Neural encoding and processing of binaural cues and structural as well as neurophysiological bases of such encoding and processing; 3) Contribution of binaural neural processing to auditory functions such as sound-source localization, binaural fusion, binaural interference, spatial release from masking, auditory grouping, and auditory stream segregation; 4) Computational models of binaural processing; 5) Learning and plastic changes in binaural processing following hearing loss or alterations of acoustic environment and structural as well as physiological bases of these behavioral changes; 6) Clinical aspects of binaural processing including application of processing strategies, including research on the benefits of bilateral cochlear implantation, and the neural correlates thereof

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 Timbre Acoustics Perception and Cognition written by Kai Siedenburg and published by Springer. This book was released on 2019-05-07 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roughly defined as any property other than pitch, duration, and loudness that allows two sounds to be distinguished, timbre is a foundational aspect of hearing. The remarkable ability of humans to recognize sound sources and events (e.g., glass breaking, a friend’s voice, a tone from a piano) stems primarily from a capacity to perceive and process differences in the timbre of sounds. Timbre raises many important issues in psychology and the cognitive sciences, musical acoustics, speech processing, medical engineering, and artificial intelligence. Current research on timbre perception unfolds along three main fronts: On the one hand, researchers explore the principal perceptual processes that orchestrate timbre processing, such as the structure of its perceptual representation, sound categorization and recognition, memory for timbre, and its ability to elicit rich semantic associations, as well as the underlying neural mechanisms. On the other hand, timbre is studied as part of specific scenarios, including the perception of the human voice, as a structuring force in music, as perceived with cochlear implants, and through its role in affecting sound quality and sound design. Finally, computational acoustic models are sought through prediction of psychophysical data, physiologically inspired representations, and audio analysis-synthesis techniques. Along these three scientific fronts, significant breakthroughs have been achieved during the last decade. This volume will be the first book dedicated to a comprehensive and authoritative presentation of timbre perception and cognition research and the acoustic modeling of timbre. The volume will serve as a natural complement to the SHAR volumes on the basic auditory parameters of Pitch edited by Plack, Oxenham, Popper, and Fay, and Loudness by Florentine, Popper, and Fay. Moreover, through the integration of complementary scientific methods ranging from signal processing to brain imaging, the book has the potential to leverage new interdisciplinary synergies in hearing science. For these reasons, the volume will be exceptionally valuable to various subfields of hearing science, including cognitive auditory neuroscience, psychoacoustics, music perception and cognition, but may even exert significant influence on fields such as musical acoustics, music information retrieval, and acoustic signal processing. It is expected that the volume will have broad appeal to psychologists, neuroscientists, and acousticians involved in research on auditory perception and cognition. Specifically, this book will have a strong impact on hearing researchers with interest in timbre and will serve as the key publication and up-to-date reference on timbre for graduate students, postdoctoral researchers, as well as established scholars.

Download or read book The Auditory Brain and Age Related Hearing Impairment written by Jos J. Eggermont and published by Academic Press. This book was released on 2019-01-03 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Auditory Brain and Age-Related Hearing Impairment provides an overview of the interaction between age-related hearing impairments and cognitive brain function. This monograph elucidates the techniques used in the connectome and other brain-network studies based on electrophysiological methods. Discussions of the manifestations of age-related hearing impairment, the causes of degradation of sound processing, compensatory changes in the human brain, and rehabilitation and intervention are included. There is currently a surge in content on aging and hearing loss, the benefits of hearing aids and implants, and the correlation between hearing loss, cognitive decline and early onset of dementia. Given the changing demographics, treatment of age-related hearing impairment need not just be bottom-up (i.e., by amplification and/or cochlear implantation), but also top-down by addressing the impact of the changing brain on communication. The role of age-related capacity for audio-visual integration and its role in assisting treatment have only recently been investigated, thus this area needs more attention. - Relates the techniques used in the connectome and other brain-network studies to the human auditory-cortex and age-related hearing loss research findings - Examines the side effects of age-related hearing impairment and their impact on the quality of life for the elderly - Evaluates the importance of multi-modal means in the rehabilitation of the elderly with hearing aids and cochlear implants - Discusses the role of neurostimulation and various training procedures to halt, or potentially reverse, cognitive decline in the elderly
