How Does The Ear Work?

The ear consists of 3 main parts, the inner, middle and outer ear. The outer ear (the visible bit) opens into the ear canal. The eardrum separates the ear canal from the middle ear. 3 small bones in the inner ear, the malleus, incus and stapes, also referred to as the hammer, anvil and stirrup, help transfer sound to the inner ear, which leads to the auditory nerve, (hearing nerve) which leads to the brain. Any source of sound sends vibrations or soundwaves into the ear, which travel through the ear opening, down the ear canal and strike the eardrum, causing it to vibrate. These vibrations are directed to the small bones in the middle ear, which transmit them to the auditory nerve in the inner ear. The vibrations then become nerve impulses and travel directly to the brain, which clarify the impulses as sound. This all happens extremely fast.
