ironpatriot · Answer

Sound waves enter through the outer ear, then sound waves move through the ear canal. Next sound waves strike the eardrum, causing it to vibrate, then vibrations enter the middle ear. Then the hammer picks up the vibrations, then vibrations are passed to the anvil. Next the vibrations are transmitted to the stirrup, then a vibrating membrane transmits vibrations to the inner ear, and then vibrations are channeled into the cochlea. Then nerve cells detect vibrations and convert them to electrical impulses, then electrical impulses are transmitted to the brain. Then the brain interprets electrical impulses as sound.
