Narrator: The sense of hearing results from conversion of mechanical
energy, in the form of a sound wave, into electrical energy by the
structures of the outer, middle, and inner ear. Sound waves from the
environment impinge upon the ear canal where they are directed to
the tympanic membrane, or eardrum. The tympanic membrane
vibrates at the same frequency as the sound wave. The vibration of
the tympanic membrane is transmitted to the cochlea by middle ear
bones called the malleus, incus, and stapes. These bones serve to
reduce the amplitude of motion but increase the force exerted on the
oval window. The sound wave is then efficiently transmitted into the
paralymph of the cochlea.
