Sound is the vibration of objects. We perceive sound as the ear drums move from the sound pressure. Then, this vibration is transformed into electrical impulses, which are sent to the brain. The transformation of the electrical impulse occurs inside the outer, the middle and the inner parts of the ears. The outer ear is called the external sound-gathering part of the ear. Its function is to gather sound energy and focuses it on the eardrum. The middle ear, an air-filled chamber serves as an amplifier of vibration. The inner ear is where the cochlea is located and also where we perceive sound. While cochlea plays an important part in hearing perception, how sounds move from there to the brain is even more complicated. The vibration of the membrane moves the hair, which sends signals to the roots, the spiral ganglia, the cranial nerve and then the brain. These impulses, when interpreted by our brain, lead to
