Available in PDF, EPUB and Kindle. Book excerpt: Our work has centered on the discovery of the MDI or Modulation Detection Interference phenomenon, in which the modulation properties of tonal components in multi-tone complexes can not be processed when all the tones are modulated at the same low modulation rate as well as when the tones are not modulated or when the modulation rates differ for different components. We have argued that MDI results from the fact that the coherent modulation of all of the components fuse them into a single auditory image, and since coherent modulation was the basis of the perceptual fusion, temporal modulation for any one tone is not easily processed. We recently tested a corollary to this assumption. That is, when tonal complexes are fused into an auditory image based on coherent temporal modulation and MDI occurs, can subjects still process other attributes of the tones (e.g. changes in frequency and intensity) since these other attributes were not the basis for the tones being fused into a single image.

Download or read book Auditory Processing of Complex Sounds written by William A. Yost and published by Routledge. This book was released on 2016-07-07 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1987, this book is the result of a workshop on the processing of complex sounds held in 1986. All of the important contributions that are being made to understanding auditory processing of complex sounds could not be included in a single volume. However, the chapters do touch base with many of the lines of research and theory on complex sound and its perception at the time, and was felt that they should provide both food for thought and a broad introduction to the literature on a topic that the editors were sure would be studied intensely in the following couple of decades.

Available in PDF, EPUB and Kindle. Book excerpt: All natural auditory signals, including human speech and animal communication signals, are spectrally and temporally complex, that is, they contain multiple frequencies and their frequency composition, or spectrum, varies over time. The ability of hearers to identify and localize these signals depends on analysis of their spectral composition. For the overwhelming majority of human listeners spoken language is the major means of social communication, and this communication therefore depends on spectral analysis. Spectral analysis begins in the cochlea, but is then elaborated at various stages along the auditory pathways in the brain that lead from the cochlea to the cerebral cortex. The broad purpose of Auditory Spectral Processing is to provide a comprehensive account of the way in which spectral information is processed in the brain and the way in which this information is used by listeners to identify and localize sounds. Examines spectral processing mechanisms at different levels along the auditory neuraxis, from the cochlear nucleus to the cortex Reviews in detail psychophysical and neurophysiological evidence on the way in which spectral information is processed within and across frequency channels Presents information on the nature of the spectral information required for speech and music perception Examines a series of issues that relate to the role of spectral analysis in higher order/cognitive aspects of hearing and in clinical and applied contexts

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 Auditory Signal Processing written by Daniel Pressnitzer and published by Springer Science & Business Media. This book was released on 2006-03-14 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the papers that were presented at the XIIIth International Symposium on Hearing (ISH), which was held in Dourdan, France, between August 24 and 29, 2003. From its first edition in 1969, the Symposium has had a distinguished tradition of bringing together auditory psychologists and physiologists. Hearing science now also includes computational modeling and brain imaging, and this is reflected in the papers collected. The rich interactions between participants during the meeting were yet another indication of the appositeness of the original idea to confront approaches around shared scientific issues. A total of 62 solicited papers are included, organized into 12 broad thematic areas ranging from cochlear signal processing to plasticity and perceptual learning. The themes follow the sessions and the chronological order of the paper presentations during the symposium. A notable feature of the ISH books is the transcription of the discussions between participants. A draft version of the book is circulated before the meeting, and all participants are invited to make written comments, before or during the presentations. This particularity is perhaps what makes the ISH book series so valuable as a truthful picture of the evolution of issues in hearing science. We tried to uphold this tradition, which was all the easier because of the excellent scientific content of the discussions.

Download or read book The Perceptual Structure of Sound written by Dik J. Hermes and published by Springer Nature. This book was released on 2023-06-10 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive review of how acoustic waves are processed by the auditory system into structured sounds such as musical melodies, speech utterances, or environmental sounds. After an introduction, an overview is given of how the ears distribute acoustic information over a large array of frequency channels that contain the auditory information used by the central nervous system to generate a mental image of what is happening around the listener. This process, called auditory scene analysis, consists of two stages. In the first stage, auditory units are formed such as musical tones and speech syllables. Each auditory unit is perceived at a well-defined moment in time, the beat location of that auditory unit. Moreover, from this process of auditory-unit formation, the auditory attributes of these auditory units emerge, such as their timbre, their pitch, their loudness, and their perceived location. Each of these attributes is discussed in the corresponding chapter. In the second stage of auditory scene analysis, auditory-stream formation, the successive auditory units are integrated into auditory streams, i.e., temporally structured sequences of auditory units that are perceived as emanating from one and the same sound source. Examples of such auditory streams are musical melodies and the utterances of one speaker. The temporal structure of an auditory stream, its rhythm, is determined by the beat locations of its auditory units. The role played by the auditory attributes of the consecutive auditory units is discussed. The melodies of musical streams and the intonation contours of spoken utterances emerge from this process. In music, the beats of parallel streams generally fit into a metric pattern, and, depending on harmony, simultaneous tones can be perceived as consonant or dissonant. Finally, the book contains many sound examples including the MATLAB scripts with which they are generated.

Download or read book The Human Auditory Cortex written by David Poeppel and published by Springer Science & Business Media. This book was released on 2012-04-12 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in a complex and dynamically changing acoustic environment. To this end, the auditory cortex of humans has developed the ability to process a remarkable amount of diverse acoustic information with apparent ease. In fact, a phylogenetic comparison of auditory systems reveals that human auditory association cortex in particular has undergone extensive changes relative to that of other species, although our knowledge of this remains incomplete. In contrast to other senses, human auditory cortex receives input that is highly pre-processed in a number of sub-cortical structures; this suggests that even primary auditory cortex already performs quite complex analyses. At the same time, much of the functional role of the various sub-areas in human auditory cortex is still relatively unknown, and a more sophisticated understanding is only now emerging through the use of contemporary electrophysiological and neuroimaging techniques. The integration of results across the various techniques signify a new era in our knowledge of how human auditory cortex forms basis for auditory experience. This volume on human auditory cortex will have two major parts. In Part A, the principal methodologies currently used to investigate human auditory cortex will be discussed. Each chapter will first outline how the methodology is used in auditory neuroscience, highlighting the challenges of obtaining data from human auditory cortex; second, each methods chapter will provide two or (at most) three brief examples of how it has been used to generate a major result about auditory processing. In Part B, the central questions for auditory processing in human auditory cortex are covered. Each chapter can draw on all the methods introduced in Part A but will focus on a major computational challenge the system has to solve. This volume will constitute an important contemporary reference work on human auditory cortex. Arguably, this will be the first and most focused book on this critical neurological structure. The combination of different methodological and experimental approaches as well as a diverse range of aspects of human auditory perception ensures that this volume will inspire novel insights and spurn future research.

Download or read book Processing Strategies of the Auditory System for Improving the Detection of Masked Signals written by Bastian Epp and published by Logos Verlag Berlin GmbH. This book was released on 2010 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The auditory system of mammals is a highly developed sensory system that facilitates the analysis and the communication in complex acoustical scenes. For the analysis of incoming sounds, the auditory systems makes use of a large variety of physical signal properties that are processed within various mechanical and neural processing stages along the auditory pathway. The scope of this thesis was to investigate processing strategies that contribute to the outstanding performance of the auditory system to detect signals in complex acoustical scenes. Using methods from psychoacoustics and signal processing techniques, it has been shown that a combination of coherent intensity fluctuations in different frequency regions and interaural disparities are processed in a highly efficient way. With the application of a physical nonlinear and active model of the cochlea, the basis was provided for separating contributions of mechanical and neural processing stages to the analysis of complex acoustical scenes.

Download or read book Processing of relevant characteristics of complex sounds in normal hearing listeners and cochlear implant users written by Wiebke Heeren and published by Logos Verlag Berlin GmbH. This book was released on 2015-06-15 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The auditory processing of complex signals is not yet fully understood making a clearer insight into auditory system processes worth aspiring to. One approach for this purpose is to gain a better understanding of the relations between physical parameters and hearing sensations by means of psychoacoustics. Suitable measures such as loudness help to characterize the perception of sound leading to more sophisticated loudness models which could be useful in optimizing hearing devices such as cochlear implants. The scope of this thesis therefore is the suprathreshold perception of sounds with different spectral, temporal and spatial content in normal-hearing listeners and cochlear implant users. Among others, this covers the applicability of categorical loudness scaling as a fast procedure to assess partial loudness as well as binaural and spatial hearing in cochlear implant users in a free-field measurement setup providing realistic spatial cues.

Available in PDF, EPUB and Kindle. Book excerpt: Despite widespread interest in virtual reality, research and development efforts in synthetic environments (SE)â€"the field encompassing virtual environments, teleoperation, and hybridsâ€"have remained fragmented. Virtual Reality is the first integrated treatment of the topic, presenting current knowledge along with thought-provoking vignettes about a future where SE is commonplace. This volume discusses all aspects of creating a system that will allow human operators to see, hear, smell, taste, move about, give commands, respond to conditions, and manipulate objects effectively in a real or virtual environment. The committee of computer scientists, engineers, and psychologists on the leading edge of SE development explores the potential applications of SE in the areas of manufacturing, medicine, education, training, scientific visualization, and teleoperation in hazardous environments. The committee also offers recommendations for development of improved SE technology, needed studies of human behavior and evaluation of SE systems, and government policy and infrastructure.

Download or read book Auditory Frequency Selectivity written by Brian Moore and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most fundamental aspects of the auditory system is its frequency selectivity - the ability to resolve a complex sound into frequency compOhents. This ability plays a role in many aspects of auditory perception, including: the masking of one sound by another; the perception of pitch for pure tones and complex tones; the perception of timbre; the perception of the relative phase of components in complex sounds; and the perception of loudness. Over the last decade, there have been considerable advances in our understanding of frequency selectivity, both at the physiological and psychophysical level, and rapid progress continues to be made. This book summarizes the proceedings of a NATO Advanced Research Workshop on Auditory Frequency Selectivity which was held in Wolfson College, Cambridge from June 23rd to 27th, 1986. The Workshop brought together leading researchers from all disciplines relevant to the topic, with the aim of reviewing and consolidating the latest research findings, and identifying areas of uncertainty or controversy where further research is needed. The book is aimed primarily at research scientists and research students in the fields of psychology, audiology, auditory physiology, biophysics, medicine, acoustical engineering, noise control, communication and speech science. It should also be useful for advanced undergraduates in these disciplines. A feature of the book is that it includes summaries of the discussions which followed the presentation of each paper at the Workshop.
