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 book Mike Goldsmith looks at the science of sound and explores sound in different contexts, covering the audible and inaudible, sound underground and underwater, acoustic and electric, and hearing in humans and animals. He also considers the problem of sound out of place - noise and its reduction.-- Source other than the Library of Congress.
