The major aim of this book is to introduce the ways in which scientists approach and think about a phenomenon -- hearing -- that intersects three quite different disciplines: the physics of sound sources and the propagation of sound through air and other materials, the anatomy and physiology of the transformation of the physical sound into neural activity in the brain, and the psychology of the perception we call hearing. Physics, biology, and psychology each play a role in understanding how and what we hear. The text evolved over the past decade in an attempt to convey something about scientific thinking, as evidenced in the domain of sounds and their perception, to students whose primary focus is not science. It does so using a minimum of mathematics (high school functions such as linear, logarithmic, sine, and power) without compromising scientific integrity. A significant enrichment is the availability of a compact disc (CD) containing over 20 examples of acoustic demonstrations referred to in the book. These demonstrations, which range from echo effects and filtered noise to categorical speech perception and total more than 45 minutes, are invaluable resources for making the text come alive.

Fundamentals of Sound (2nd ed., 2016) is a book designed for persons interested in learning about the physics of sound and how it applies to the speech and hearing processes. The physics of sound is basic to the understanding of how we communicate, but students interested in speech and hearing may not possess the background for attaining a deep understanding within their own areas of study. The book is meant to provide the basics in the physics of sound, at a level appropriate for undergraduate non-physical-science majors, for further study of speech and hearing.

An original ethnography of sound and listening in one of our major institutions, Hearing and the Hospital reveals the hospital to be a space in which several modes of listening are simultaneously in play and in which different layers of auditory knowledge and experience coexist. Engaging with Sound Studies, the Anthropology of the Senses, Medical Anthropology and Science and Technology Studies in this volume, Tom Rice shows how sound and listening produce, articulate and mediate social relations inside the hospital; how listening acquires direction and focus within that environment; and how certain sounds become endowed with particular meanings and associations. He also exposes many of the sensory minutiae that both underpin and undermine the production of medical knowledge and skill. Hearing and the Hospital creates an acoustic interrogation of hospital life, and in doing so questions accepted ideas about the sense of hearing itself. There's a great deal to admire in Tom Rice's ethnography of the aural politics of the hospital. First because it represents a unique conjunction of the ethnography of sound and senses with medical anthropology and social studies of science. Next because it patiently details how sound as a way of knowing so deeply informs social practices of medical listening. And finally because it is so successful in revealing both how hospitals and bodies pulse as acoustic spaces, and how patients and doctors professionalize, personalize, and participate as situated listeners.(Steven Feld, Distinguished Professor of Anthropology and Music, University of New Mexico). Tom Rice is Lecturer in Anthropology at the University of Exeter, and specializes in auditory culture. As well as writing and teaching on sound he has produced audio pieces including the BBC Radio 4 feature The Art of Water Music.
