What kinds of hearing loss are there?
There are three types of hearing loss.
Sensorineural hearing loss occurs when the inner ear, or the auditory nerve is damaged. It is the most common type of hearing loss and is, in a majority of cases, permanent.
Conductive hearing loss arises when sounds are unable to pass from the outer ear to the inner ear, which can be caused by a blockage such as earwax or damage to the eardrum or ossicular bones. It is in many cases temporary and can be treated medically.
Mixed hearing loss is when both sensorineural hearing loss and conductive hearing loss occur in the same ear. Treatment for the conductive component can help alleviate the degree of the hearing loss but the underlying sensorineural hearing loss will remain.
