The Power of Sound!
... As sound enters your ear the first thing it encounters is your ear drum. The ear drum detects these tiny ripples and sends the vibrations to the middle ear and on to the inner ear, or Cochlea. The Cochlea contains tiny hairs which send electrical impulse to the brain which converts this Impulse to s ...
