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.

This second edition of A Dictionary of Audiology provides more than 230 fully cross-referenced entries that define and describe essential terms in the field of audiology. These entries expand greatly on the content present in our general medical reference dictionaries to provide an authoritative source for any students and practitioners needing specialized information on audiology. This second edition includes new illustrations and recommended web links, as well as more than 30 new entries on subjects such as balance, Electrocochleography, otalgia, and paediatric audiometry.

For the 119 species of marine mammals, as well as for some other aquatic animals, sound is the primary means of learning about the environment and of communicating, navigating, and foraging. The possibility that human-generated noise could harm marine mammals or significantly interfere with their normal activities is an issue of increasing concern. Noise and its potential impacts have been regulated since the passage of the Marine Mammal Protection Act of 1972. Public awareness of the issue escalated in 1990s when researchers began using high-intensity sound to measure ocean climate changes. More recently, the stranding of beaked whales in proximity to Navy sonar use has again put the issue in the spotlight. Ocean Noise and Marine Mammals reviews sources of noise in the ocean environment, what is known of the responses of marine mammals to acoustic disturbance, and what models exist for describing ocean noise and marine mammal responses. Recommendations are made for future data gathering efforts, studies of marine mammal behavior and physiology, and modeling efforts necessary to determine what the long- and short-term impacts of ocean noise on marine mammals.

Psychoacoustics: Auditory Perception of Listeners with Normal Hearing and Hearing Loss, Second Edition provides an overview of the field of psychoacoustics, with a primary focus on auditory perception. The book retains its focus on applications of psychoacoustics to clinical audiology, and its modular organization, with each chapter including relevant information around a specific topic. Within each chapter, acoustics, physiology, and perception by adult listeners with normal hearing and those with hearing loss, as they relate to that topic, are presented. The influence of hearing loss on these general auditory abilities is discussed in every chapter. Components of the book also include the role of psychoacoustics in audiological assessment and treatment. The text is ideal for audiology students who intend on having a clinical career and need an understanding of both normal and impaired auditory perception. It is intended to give students sufficient information to understand how the ear achieves auditory perception, what the capabilities of the ear are, and how hearing loss influences that perception. It also provides students with a foundation for further study in the area and to apply psychoacoustic principles to diagnostic audiology and audiological rehabilitation. New to the Second Edition: * 70 new figures to clarify some points and facilitate students’ understanding of the material * New chapter that focuses exclusively on the perception by individuals wearing hearing aids and cochlear implants * New section on the perceptual consequences of sensorineural hearing loss on everyday listening added to each chapter * Revamped chapter on Psychoacoustics and Advanced Clinical Auditory Assessment now solely addresses elements within diagnostic audiology that are based on psychoacoustics, with added content on tinnitus assessment, automated (Békésy) audiometry, retrocochlear and pseudohypacusis evaluation, and the identification of dead regions * Enhanced focus on inclusivity, such as alternative versions of some demonstrations designed to be more accessible to individuals with hearing loss, and a new section on the contributions of women and BIPOC scientists to the field of psychoacoustics Key Features: * Learning objectives and summaries begin and end each chapter to convey the goals of the text and review student comprehension * Each chapter contains exercises designed to develop critical thinking about psychoacoustics * Chapters include the following: introduction, relevant acoustics, important physiological studies, perception by normal-hearing listeners, and perception by listeners who have sensorineural hearing loss * Emphasis on applied learning for more effective and efficient learning of the material Disclaimer: Please note that ancillary content such as lab exercises are not included as published in the original print version of this book.

In twenty essays on subjects such as noise, acoustics, music, and silence, Keywords in Sound presents a definitive resource for sound studies, and a compelling argument for why studying sound matters. Each contributor details their keyword's intellectual history, outlines its role in cultural, social and political discourses, and suggests possibilities for further research. Keywords in Sound charts the philosophical debates and core problems in defining, classifying and conceptualizing sound, and sets new challenges for the development of sound studies. Contributors. Andrew Eisenberg, Veit Erlmann, Patrick Feaster, Steven Feld, Daniel Fisher, Stefan Helmreich, Charles Hirschkind, Deborah Kapchan, Mara Mills, John Mowitt, David Novak, Ana Maria Ochoa Gautier, Thomas Porcello, Tom Rice, Tara Rodgers, Matt Sakakeeny, David Samuels, Mark M.

Audionarratology is a new 'postclassical' narratology that explores interfaces of sound, voice, music and narrative in different media and across disciplinary boundaries. Drawing on sound studies and transmedial narratology, audionarratology combines concepts from both while also offering fresh insights. Sound studies investigate sound in its various manifestations from disciplinary angles as varied as anthropology, history, sociology, acoustics, articulatory phonetics, musicology or sound psychology. Still, a specifically narrative focus is often missing. Narratology has broadened its scope to look at narratives from transdisciplinary and transmedial perspectives. However, there is a bias towards visual or audio-visual media such as comics and graphic novels, film, TV, hyperfiction and pictorial art. The aim of this book is to foreground the oral and aural sides of storytelling, asking how sound, voice and music support narrative structure or even assume narrative functions in their own right. It brings together cutting-edge research on forms of sound narration hitherto neglected in narratology: radio plays, audiobooks, audio guides, mobile phone theatre, performance poetry, concept albums, digital stories, computer games, songs.
