The Hearing Process

Paper Summary:

The following paper provides the reader with facts and information on how sound is produced, its characteristics, the ways in which humans process it and how in turn we can prevent hearing problems by treating infections in the ear and using ear plugs in increased noise levels.

From the Paper:

"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. (GSLC) These ear parts are so organized as to transmit sound waves to the brain. 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."
