How Does the Ear Work?

Sound from the external environment is collected by our outer ear and then funneled down to the outer ear or ear canal. Sound vibrations causes movement in the eardrum along with a chain of three small bones that are connected to it. This is the middle ear.
The middle ear is responsible for intensifying the energy coming from the sound vibrations and also for delivering the vibrations to the inner ear or the cochlea.
Within the cochlea are tiny hair-like cells which are connected to the fibers found in the acoustic or hearing nerve. The sound vibrations which enter the cochlea create a certain wave, which travels through our fluid-filled ear.
The wave will then result in a movement of the hair-like cells which will then generate the electro-chemical signals. The signals will then travel via the acoustic nerve to our brain where they become recognized as sound.
