Question

The most common cause of hearing loss is exposure to loud noise such as music, which can permanetly damage the hair cells of the cochlea. Would you expect this to result in conductive or in sensorineural hearing loss? What results would you expect from the Rinne and Weber tests in an individual with noise-induced hearing loss?

A standard hearing aid functions by amplifying the sound conducted through the external auditory canal. Explain why this type of hearing aid is effective for conductive hearing loss, but not sensorineural hearing loss?

Explanation / Answer

he damage caused by noise, called sensorineural hearing loss, can be caused by several factors other than noise, but noise-induced hearing loss is different in one important way – it can be reduced or prevented altogether.

TEST:

RINNE test- both air conduction and bone conduction is diminished or lost.

WEBER test- sound is better heard in diseased ear .
