Types of Hearing Loss:
There are three main types of hearing loss, these are....
Sensorineural hearing loss is the most common type of hearing loss. It is permanent and caused either by damage to tiny hair-like cells in the inner ear or to the auditory nerve. The auditory nerve carries important information about the loudness, pitch and meaning of sounds to the brain. Most adults with hearing loss have a sensorineural loss. Sensorineural hearing loss can often result in difficulty understanding sound or speech even though it is loud enough to hear.
Conductive hearing loss is caused by a mechanical problem in the outer or middle ear or an obstruction in the ear canal such as ear wax that blocks sound from getting to the eardrum. It can be permanent but more often; it is temporary and can be medically treated.
Mixed hearing loss results when there are components of both sensorineural and conductive hearing loss present.
