Study Purpose
The purpose of the hearing research experiment is to understand the effects of experimentally induced conductive hearing loss on spectral and temporal aspects of sound transmission through the ear. The ability to hear is a critical aspect to understanding the world around us. The hearing process occurs by sound waves entering the auditory canal, coming in contact with the eardrum and causing it to vibrate. These vibrations cause sound waves which are then passed through the ossicles that lead to the inner ear. As the vibrations are passing thought through, the motion is setting fluid into the inner ear moving the inner hair cells. This processes into vibrations to the nerve impulses which are then carried to the brain by the auditory nerve and is transmitted into the sound that we hear however many people do not experience this due to hearing loss. Causes of hearing loss may be congenital of which would be hearing loss at birth or acquired hearing loss which would be hearing loss after birth. Other causes may be severe ear infections, extreme noise, ototoxic medications, and chemical exposure effects. The type of hearing loss that the study focused on was conductive hearing loss that occurs when “sound is not conducted efficiently through the outer ear canal to the eardrum and the tiny bones (ossicles) of the middle ear” (ASHA 2015). What is significant about this type of hearing loss is that due its normality of a reduction of sound level or the ability to…
