Handbook of Modern Techniques in Auditory Cortex


Book Description

A host of new techniques have recently been developed in the study and modelling of the auditory pathway. These techniques, made practical thanks to recent development in computer power and memory, are often referred to as broadband methods. These methods have allowed us to better understand how complex sounds such as music and running speech are encoded along the auditory pathway in a noise-robust fashion, and the resulting cortical models have been used in speech recognition, vehicle identification and speaker identification with great success. These techniques were developed and refined over the last 20 years, and as a result, the published literature offers a scattered, and sometimes seemingly contradictory, account. The different stimuli used might give an impression of incompatibility between the different research groups, with no clear reason to choose one approach over the other. Recently, these methods were shown to be almost equivalent.This leads to a very confusing situation for a researcher who wants to apply these new techniques to his or her current research: depending on how far back the researcher goes, the literature will appear to change over, and even to be self-contradictory. This book is the first to present, in a single volume, the different broadband methods, their different philosophies, their relative advantages and disadvantages, and a methodology that will help the would-be-practitioner get started, navigate the literature, and chose the method most appropriate to her needs.




The Human Auditory Cortex


Book Description

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.




Timbre: Acoustics, Perception, and Cognition


Book Description

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.




The Auditory System at the Cocktail Party


Book Description

The Auditory System at the Cocktail Party is a rather whimsical title that points to the very serious challenge faced by listeners in most everyday environments: how to hear out sounds of interest amid a cacophony of competing sounds. The volume presents the mechanisms for bottom-up object formation and top-down object selection that the auditory system employs to meet that challenge.

The New Handbook of Multisensory Processing


Book Description

The major reference work for a rapidly advancing field synthesizes central themes, reports on current findings, and offers a blueprint for future research. Scientists' attempts to understand the physiology underlying our apprehension of the physical world was long dominated by a focus on the individual senses. The 1980s saw the beginning of systematic efforts to examine interactions among different sensory modalities at the level of the single neuron. And by the end of the 1990s, a recognizable and multidisciplinary field of "multisensory processes" had emerged. More recently, studies involving both human and nonhuman subjects have focused on relationships among multisensory neuronal ensembles and their behavioral, perceptual, and cognitive correlates. The New Handbook of Multisensory Processing synthesizes the central themes in this rapidly developing area, reports on current findings, and offers a blueprint for future research. The contributions, all of them written for this volume by leading experts, reflect the evolution and current state of the field. This handbook does more than simply review the field. Each of the volume's eleven sections broadly surveys a major topic, and each begins with a substantive and thought-provoking commentary by the section editor that identifies the major issues being explored, describes their treatment in the chapters that follow, and sets these findings within the context of the existing body of knowledge. Together, the commentaries and chapters provide an invaluable guide to areas of general agreement, unresolved issues, and topics that remain to be explored in this fast-moving field.




Auditory Temporal Processing and its Disorders


Book Description

'Auditory temporal processing' determines our understanding of speech, our appreciation of music, our ability to localize a sound source, and even to listen to a person in a noisy crowd. Sound is dynamic and as such has temporal and spectral content. In disorders such as auditory neuropathy and MS, problems can occur with these temporal representations of sound, leading to a mismatch between auditory sensitivity and speech discrimination. In dyslexia, specific language impairment, and auditory processing disorders, similar problems occur early in life and set up additional cognitive speech processing problems. It has also been found that in disorders such as autism, schizophrenia and epilepsy, temporal processing deficits can occur. This book reviews comprehensively the mechanisms for temporal processing in the auditory system, looking at how these underlie specific clinical disorders, with implications for their treatment. Written by a prolific researcher in auditory neuroscience, this book is valuable for auditory neuroscientists, audiologist, neurologists, and speech language pathologists.
