What happens to the ear drum when a sound hit's it?

Answer 1

Basically the ear drum vibrates and causes the three small bones in your ear to vibrate. The vibration of the last bone causes vibration on the oval window of the Cholea, the oval window vibrations cause the fluid within the semi circular canal to travel back and forwards over the basilar membrane. This is linked to neurones which take the information of which frequency you are hearing to the brain.

So the vibration frequency of the ear drum depends on what pitch of sound you hear so the best thing to say would be. The frequency of vibrations increases with high pitched sounds and decreased with low pitched sounds.

Answer 2

When a sound wave hits the eardrum, the pressure variations in the wave cause the eardrum to vibrate. These vibrations are then transmitted through the middle ear bones to the cochlea, where they are converted into electrical signals and sent to the brain for processing and interpretation of sound.

Answer 3

sound travelling down the ear canal hits the eardrum, which vibrates ... just like a drum!

Answer 4

The ear drum vibrates at greater amplitude.

Answer 5

It vibrates
