Sound-Power Flow: A practitioner's handbook for sound intensity is a guide for practitioners and research scientists in different areas of acoustical science. There are three fundamental quantities in acoustics: sound pressure, sound particle velocity, and sound intensity. This book is about sound intensity and demonstrates the advantages and uses of acoustical sensing compared with other forms of sensing. It describes applications such as: measuring total sound power; directional hearing of humans and mammals; echolocation; measuring sound-power flow in ducts; and uses of non-contact, focused, high-frequency, pulse-echo ultrasonic probes. This book presents computational approaches using standard mathematics, and relates these to the measurement of sound-power flow in air and water. It also uses linear units rather than logarithmic units – this making computation in acoustics simpler and more accessible to advanced mathematics and computing. The book is based on work by the author and his associates at General Motors, the University of Mississippi, and Sonometrics.
Auditory Perception of Sound Sources covers higher-level auditory processes that are perceptual processes. The chapters describe how humans and other animals perceive the sounds that they receive from the many sound sources existing in the world. This book will provide an overview of areas of current research involved with understanding how sound-source determination processes operate. This book will focus on psychophysics and perception as well as being relevant to basic auditory research. Contents: Perceiving Sound Sources: An Overview William A.

A comprehensive, kid-friendly examination of how sound works. How does sound happen? How do we hear it? What makes some sounds loud and some soft? Some high pitched and some low pitched? How do humans and animals use sound to communicate? Which sounds happen naturally, and which are created for a specific purpose? This charming picture book explores all of these questions in easy-to-understand and child-friendly language, offering a gentle introduction to how sound works. Kids are experts at making noise. Now they’ll want to stop and listen, too!
Sound is integral to how we experience the world, in the form of noise as well as music. But what is sound? What is the physical basis of pitch and harmony? And how are sound waves exploited in musical instruments? In this Very Short Introduction Mike Goldsmith looks at the science of sound and explores sound in different contexts, covering the audible and inaudible, sound underground and underwater, accoustic and electric, and hearing in humans and animals. He also considers the problem of sound out of place - noise and its reduction. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
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.

"The Fundamentals of Sound Science teaches the principles of the physics of sound, as well as basic principles of physics, by linking them to music and musical instruments. The book begins by asking students to question the meaning of sound itself. What is sound? How far and how fast does it travel? By asking students to think about sound in this way, the material is able to connect our daily experience of sound to principles of physics such as distance, velocity, scalars, and vectors. Through the next six chapters students learn about harmonic motion, waves, the sources and physical properties of sound, and measurements of loudness. The second half of the book uses music as the vehicle for a deeper exploration of sound. Students study some basic musicianship, including articulation, intervals, and harmonic series. These concepts become the springboard for an examination of the Fourier Analysis of Simplest Sound Spectra, which encompasses steady tones, periodic waves of arbitrary form, square, triangular, and sawtooth waves, and modulated tones. Different families of instruments are discussed in depth: percussion, strings, flutes and recorders, woodwinds, and finally the human voice. The book concludes with a chapter on room acoustics, which covers the precedence effect and reverberations. Each chapter is filled with detailed explanations, and numerous examples are used to enhance student understanding. Study questions are included to encourage critical thinking, and prepare students for tests. Chapter summaries aid retention by reviewing terms and relations. By finding the common ground between physics and music, The Fundamentals of Sound Science strengthens understanding of both, revealing that many principles of the physical world are a part of our common, taken for granted, daily experience. All we have to do is listen. The Fundamentals of Sound Science can be used for introductory courses in physics, including those at the high school level. The accessibility of the material makes the book appropriate for non-majors at the university level, and students can achieve mastery of the content without a background in mathematics, making the book ideal for general education courses. Elena Borovitskaya earned her Ph.D. in physics and mathematics at the Institute of Applied Physics, Russian Academy of Science in Nizhni Novgorod, Russia. Her area of expertise is the physics of low-dimensional systems such as quantum wells, quantum wires, and quantum dots. Dr. Borovitskaya also studied at a music school in Nizhni Novgorod. Her joint areas of interest and expertise have enabled her to connect the language of physics and the language of music. Currently she is a faculty member at Temple University in Philadelphia, where she enjoys teaching a variety of courses, musical acoustics being her favorite. "

Two of the most acclaimed reference works in the area of acoustics in recent years have been our Encyclopedia of Acoustics, 4 Volume set and the Handbook of Acoustics spin-off. These works, edited by Malcolm Crocker, positioned Wiley as a major player in the acoustics reference market. With our recently published revision of Beranek & Ver's Noise and Vibration Control Engineering, Wiley is a highly respected name in the acoustics business. Crocker's new handbook covers an area of great importance to engineers and designers. Noise and vibration control is one largest areas of application of the acoustics topics covered in the successful encyclopedia and handbook. It is also an area that has been under-published in recent years. Crocker has positioned this reference to cover the gamut of topics while focusing more on the applications to industrial needs. In this way the book will become the best single source of need-to-know information for the professional markets.
