This paper is about hearing loss. Five steps are, thus, involved in the hearing process. which are the air conduction through the external ear to the eardrum; the bone conduction through the middle ear to the inner ear; the water conduction to the Organ of Corti; the nerve conduction into the brain; and finally, the interpretation by the brain of the message received through the sound waves. We are all familiar with the three structural parts of the ear, i.e., the outer ear, the middle ear and the inner ear. In the process of hearing, we already know that it is in the outer ear that sound waves collect and from there are moved to the middle ear by vibrating against the eardrum or tympanum membrane. In the middle ear, these sound waves are changed into a mechanical type of vibration by the tiny bones there. And in the inner ear are special so-called "hair cells" that perceive these mechanical vibrations from the middle ear and trigger an impulse that is send to that specific part of the brain that hears.
