             Human Ear



         Human beings hear sound through the ears.

         Ear drum is membrane-like structure which is attached at the end
            of the canal connecting it to the outer part of the ear.

         When sound enters the ear, the vibrations vibrate the ear drum.

         The ear drum sends the vibrations to the inner ear and then the
            signal reaches the brain and sound is heard by our ears.
