THE EARS

You have two ears, one on each side of your head. This is how you know which direction a sound is coming from. The ears capture sound vibrations and send them to the brain.

The ear has three parts: the outer ear, the middle ear and the inner ear.
The outer ear is external.

• It captures sound through the pinna.
• The sound travels through the ear canal to the middle ear.

The middle ear is internal.

• The eardrum and three small bones.
• When sound reaches the eardrum, it vibrates.
• The small bones make the sound louder.

The inner ear is inside your head.

• It consists of the cochlea.
• The cochlea receives the sound vibrations.
