Question

Quizplus · Accepted Answer

Colin's injury has reduced the ability of his ear to transmit vibrations, which is a characteristic of conduction deafness. This type of deafness is caused by a problem in the outer or middle ear, such as damage to the eardrum, which interferes with the conduction of sound vibrations to the inner ear. The fact that a hearing aid greatly improves Colin's ability to hear suggests that the problem is one of conduction rather than nerve deafness, which is caused by damage to the auditory nerve. Vibration and pitch are not types of deafness but rather qualities of sound.
