Male Speaker: For you to hear, sound waves or vibrations must enter the auditory canal pass through the middle ear to be processed in the cochlea. In the middle ear, there are smallest bones of the body, the malleus, incus, and stapes together called the ossicles. When sound arrives at the ear drum, vibrations move through the ear bones into cochlea. Here in the cochlea, sound waves are converted into nerve signals and sent along the auditory nerve to the brain. The cochlea contains a system of membranes and tunnels when sound passes down the tunnel the membrane floor vibrate triggering nerve cells. Low sounds affect the far end of the cochlea, high sounds the near end. As a result, different nerves are activated allowing the brain to distinguish sounds of different pitch.
