Question

Sound waves enter the ear canal and cause the eardun to vibrate​

Answer 1

Hey there

it's your ans-..

The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the bones causes the fluid in the inner ear or cochlea to move.

have a great day

Answer 2

Explanation:

Sound waves entering the ear travel through the external auditory canal before striking the eardrum and causing it to vibrate.
