Question

Quizplus · Accepted Answer

Sound waves enter the outer ear and cause vibration of the eardrum, which in turn causes the vibration of the three small bones in the middle ear. These vibrations are transmitted to the cochlea in the inner ear, where they activate hair cells that convert the mechanical energy of the vibrations into neural impulses that can be interpreted by the brain as sound.
