The hearing mechanism is influenced by a number of factors, whether sound or physiology. These factors include the stimulus level of sound and cochlear roughness. In this work, the otoacoustic emissions was studied with the stimulus level of sound 30 dB different cases. In each case the cochlear roughness was changed to study the otoacoustic emission. Cochlear roughness changes for each case and it is noted that the hearing mechanism is affected by cochlear roughness. The most important conclusion of this work is that cochlear roughness is very important to hearing efficiency. It is clear that the stimulus level gave good results regarding the hearing mechanism.

Abstract


The hearing mechanism is influenced by a number of factors, whether sound or physiology. These factors include the stimulus level of sound and cochlear roughness. In this work, the otoacoustic emissions was studied with the stimulus level of sound 30 dB different cases. In each case the cochlear roughness was changed to study the otoacoustic emission. Cochlear roughness changes for each case and it is noted that the hearing mechanism is affected by cochlear roughness. The most important conclusion of this work is that cochlear roughness is very important to hearing efficiency. It is clear that the stimulus level gave good results regarding the hearing mechanism.
