The Basics of Sound

by Christopher Cooper

Overview

Ticking clocks, claps of thunder, the human voice—sound is anything that can be heard. Hearing sound is one thing, but understanding just how it works and what its properties are is quite another. Answering these questions and others concerning supersonic speed and breaking the sound barrier, how the human voice and ear work, and the age-old question of whether a tree falling in the forest unobserved makes any noise, this volume provides an accessible yet detailed and amply illustrated guide to the science of sound. Also included are several fun projects, which allow readers to explore in a hands-on way the nature, quality, and behavior of sound.
