How the Ears Work
Your ear is divided into three major components: the inner ear, the middle ear, and the outer ear. The outer ear is what is physically seen in our bodies. The ear canal is the path where the sound waves pass through. It is also seen from the outside. The ear canal acts like a funnel catching the sound waves and lead them to the eardrum.
The middle ear is where the eardrum is located. It is actually a small space inside the ear filled with air. In the middle ear, there are three tiny bones. Collectively, they are called the ossicles. Individually, there are the hammer, the anvil, and the stirrup. From the outer ear, sound is directed to the eardrum. Now on the eardrum, these bones move in tune with the sound that passes on the vibration toward a much smaller part of the ear, the cochlea.
The cochlea is already part of the inner ear. It has fluid in it, which, in turn, moves the hairs on the outside of the cells. Several of these hair cells create an electrical impulse that is send with the auditory nerve directly to the brain. The brain then processes the information and you are able to hear the sounds. All these processes are done in a matter of microseconds.Other Details
