The outer ear funnels sound waves to the eardrum
The Bones of the Middle Ear (hammer anvil stirrup) amplify and relay the eardrum's vibrations through the Oval Window into the fluid filled Cochlea
The resulting pressure changes in the cochlear fluid cause the Basilar Membrane that has about 16,000 tiny protruding hairs, to ripple
This in turn bends those hairs on the surface
These hair fibers then send messages to adjacent nerve fibers
These nerve fibers send the message through the Auditory Nerve, into the Auditory Cortex
