It has three main parts: the outer, middle and inner ear. The outer ear (the part that your glasses sit on) opens into the ear canal, which is separated from the middle ear by the eardrum. Tiny bones in the middle ear help to transfer sound to the inner ear, which contains the auditory nerve that transmits sounds to the brain. Any source of sound in the sends vibrations or sound waves into the air, which are funneled through the ear opening, down the ear canal, and strike the eardrum, causing it to vibrate. Those vibrations are passed through the tiny bones in the middle ear to the hearing nerve in the inner ear and become nerve impulses that are sent directly to the brain. Once in the brain, the nerve impulses are interpreted as sound – music, a voice, a car horn, etc. Fascinating, isn’t it? Visit our website to learn more!
