The human ear has three main section which consists of the outer ear. The middle ear, and inner ear. Sound waves enter your outer ear and travel through your ear canal to the middle ear. The ear canal channels the waves to your eardrum, a thin \, sensitive membrane stretched tightly over the entrance to your middle ear. The waves cause your eardrum to vibrate. It passes these vibrations on to the hammer, one to three tiny bones in your ear. The hammer vibrating causes the anvil. The small bone touching the hammer, to vibrate. The anvil passes these vibration to the stirrup, another small bone which touches the anvil. From the stirrup, the vibrations pass into the inner ear.
