Sound causes it to move like the head of a drum.
The eardrum causes them to move, and in a chain reaction they move the oval window. Problems in the middle ear cause conductive hearing loss.

The cochlea, which changes the movement of the fluid to nerve impulses for the auditory nerve which goes to the brain.
