Understanding Sound

The overarching goal of this book is to introduce non-scientists to the basic science of sound. The hope is that readers become more inquisitive, careful and informed listeners to the world around them. Along the way, you might develop an appreciation of the perspectives of science and learn (or relearn) some basic math and/or physics.
