Sound waves enter the outer ear and travel through the ear canal to the eardrum. The eardrum vibrates from these waves. These vibrations pass to three tiny bones in the middle ear: the malleus, incus, and stapes. These bones help transfer sound signals to the inner ear, completing the hearing process. Next, these vibrations pass … Read more
