How Hearing Works

                            How You Hear

First Sound Waves travel to your Pinna. The Pinna traps the

waves and direct them to the External Auditory Canal. The Waves move down

the Canal until they hit the Tympanic Membrane or Ear Drum). The Ear Drum then starts

to viberate from each

time the Waves run

into it.

The viberations move the Malleus(orHammer). The Malleus causes the Incus (or Anvil) to jiggle. The Incus then makes the Stapes (or Stirrup) viberate, which in turn viberates the Oval Window. The Oval Window makes the

liquid inside the Cochlea  to move. this movement is

picked up by the

hairlike fibres lining

the Cochlea. These

fibres convert it into

electrical signals

called "Action

Potentials". These

signals are sent down

the eight

nerves of the Cochlear Nerve.
