Transcript of The ear

The ear.

When we detect sounds, or noise, our body is changing the energy in sound waves. Sound waves are produced when the air is made from vibrating particles.

When we hear a sound, this is what actually takes place:
1.Sound waves enter the ear canal and cause the eardrum to vibrate.
2.Vibrations pass through 3 connected bones in the middle ear
3.This motion makes fluid move in the inner ear.
4.Moving fluid bends thousands of delicate hair-like cells.
5.Nerve impulses are carried to the brain by the auditory nerve
6.In the brain, these impulses are CONVERTED into what we "hear" as sound.
