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.

An integrated overview of hearing and the interplay of physical, biological, and psychological processes underlying it. Every time we listen—to speech, to music, to footsteps approaching or retreating—our auditory perception is the result of a long chain of diverse and intricate processes that unfold within the source of the sound itself, in the air, in our ears, and, most of all, in our brains. Hearing is an "everyday miracle" that, despite its staggering complexity, seems effortless. This book offers an integrated account of hearing in terms of the neural processes that take place in different parts of the auditory system. Because hearing results from the interplay of so many physical, biological, and psychological processes, the book pulls together the different aspects of hearing—including acoustics, the mathematics of signal processing, the physiology of the ear and central auditory pathways, psychoacoustics, speech, and music—into a coherent whole.

The field of spatial hearing has exploded in the decade or so since Jens Blauert's classic work on acoustics was first published in English. This revised edition adds a new chapter that describes developments in such areas as auditory virtual reality (an important field of application that is based mainly on the physics of spatial hearing), binaural technology (modeling speech enhancement by binaural hearing), and spatial sound-field mapping. The chapter also includes recent research on the precedence effect that provides clear experimental evidence that cognition plays a significant role in spatial hearing.The remaining four chapters in this comprehensive reference cover auditory research procedures and psychometric methods, spatial hearing with one sound source, spatial hearing with multiple sound sources and in enclosed spaces, and progress and trends from 1972 (the first German edition) to 1983 (the first English edition) -- work that includes research on the physics of the external ear, and the application of signal processing theory to modeling the spatial hearing process. There is an extensive bibliography of more than 900 items.

This book presents a clear and precise treatment of the physics of sound while using a level of math suitable for readers in the speech, language, hearing and health sciences. Simple mathematics, graphics, and qualitative descriptions are demonstrated to explain wave concepts, spectrograms, intensity, and decibels.

Hearing, Sound, and the Auditory in Ancient Greece represents the first wide-ranging philosophical study of the role of sound and hearing in the ancient Greek world. Because our modern western culture is a particularly visual one, we can overlook the significance of the auditory which was so central to the Greeks. The fifteen chapters of this edited volume explore "hearing" as being philosophically significant across numerous texts and figures in ancient Greek philosophy. Through close analysis of the philosophy of such figures as Homer, Heraclitus, Pythagoreans, Sophocles, Empedocles, Socrates, Plato, Aristotle, Hearing, Sound, and Auditory in Ancient Greece presents new and unique research from philosophers and classicists that aims to redirect us to the ways in which sound, hearing, listening, voice, and even silence shaped and reflected the worldview of ancient Greece.

Hearing Things is a meditation on sound’s work in literature. Drawing on critical works and the commentaries of many poets and novelists who have paid close attention to the role of the ear in writing and reading, Angela Leighton offers a reconsideration of literature itself as an exercise in hearing. An established critic and poet, Leighton explains how we listen to the printed word, while showing how writers use the expressivity of sound on the silent page. Although her focus is largely on poets—Alfred Tennyson, W. B. Yeats, Robert Frost, Walter de la Mare, Wallace Stevens, Elizabeth Bishop, Jorie Graham, and Alice Oswald—Leighton’s scope includes novels, letters, and philosophical writings as well. Her argument is grounded in the specificity of the text under discussion, but one important message emerges from the whole: literature by its very nature commands listening, and listening is a form of understanding that has often been overlooked. Hearing Things offers a renewed call for the kind of criticism that, avoiding the programmatic or purely ideological, remains alert to the work of sound in every literary text.

The Auditory System and Human Sound-Localization Behavior provides a comprehensive account of the full action-perception cycle underlying spatial hearing. It highlights the interesting properties of the auditory system, such as its organization in azimuth and elevation coordinates. Readers will appreciate that sound localization is inherently a neuro-computational process (it needs to process on implicit and independent acoustic cues). The localization problem of which sound location gave rise to a particular sensory acoustic input cannot be uniquely solved, and therefore requires some clever strategies to cope with everyday situations. The reader is guided through the full interdisciplinary repertoire of the natural sciences: not only neurobiology, but also physics and mathematics, and current theories on sensorimotor integration (e.g. Bayesian approaches to deal with uncertain information) and neural encoding.
