How Do Our Ears Hear?

Explaining how the ears work and providing information about the world around us, this book demonstrates how noise is measured and why we need two ears to tell the direction of a sound. Anatomical illustrations show the structure of the ear, and how to keep the ears in tip-top shape. This book is one of a series that looks at different parts of the body and shows how they function. It focuses particularly on the link between body parts and the senses, includes advice on health and hygiene and looks at conditions that affect the body parts.
