Ears and Hearing

Introduction

The mammalian ear is a complex and amazing instrument. By adding the dimension of sound to our repertoire of incoming information it greatly enhances our lives. The ear collects sound, transverse pressure waves travelling through the atmosphere, the water or even the ground and turns them into electrical impulses to send to our brains. Our brains then use this information to build up a sound map of the world around us, allowing us to respond to the beauty of a song or the urgency of a call for help.

The mammalian ear can conveniently be divided into three parts, the outer, middle and inner ears.
