Question

Quizplus · Accepted Answer

Conduction deafness involves problems with the conduction of sound waves through the outer and/or middle ear. Cochlear nerve degeneration, which occurs in sensorineural hearing loss, involves damage to the nerves in the inner ear that transmit sound signals to the brain. This is not a cause of conduction deafness. Impacted cerumen, otosclerosis, and middle ear infections can all cause conduction deafness.
