The Three Types Of Hearing Impairment

There are three types of hearing loss that can indicate what the underlying causes for the loss of hearing. The reasons for the loss of hearing can be sensorial, conductive or mixed. Please note, that hearing loss is different than deafness, which is why it’s considered a different disability under the IDEA act.

Sensorial Hearing Loss

The most common type of hearing is known as sensorial hearing loss. This is a total loss of hearing and results from irreparable damage done to the fine hair like cells of the inner ear that transfer sound signals from the ear to the brain, These delicate sounding implements allow the variance of distance and intensity to be defined clearly.

There is no treatment for sensorial hearing loss. This is because the capacity to repair the tiny and highly delicate cells in question exceeds the capacity of modern medical science or surgical precision. Nevertheless, the condition can be aided in some level with the help of a hearing aid or certain cochlear implants. It will be necessary for those with any level of sensorial hearing loss to take advantages of vibrating alarm clocks, captioned phones and other assistive hearing devices but the results vary.

Conductive hearing loss

A slightly less common form of hearing loss is called conductive hearing loss. This is the result of many types of obstructions that can damage the inner or outer ear and also prevent the smooth conveyance of sound to the proper sensory nerves. This type of hearing loss can be severe and permanent or it can be mild and temporary depending on the underlying causes.

There are a variety of different medical procedures that can be applied to improving the hearing of those with conductive hearing loss. Many causes of this type of hearing loss include excessive wax in the auditory canal, foreign objects, abnormal growths and more. These can be treated with a number of techniques for removing wax and foreign objects, surgically removing growths or treating infections with antibiotics. In these cases, the afflicted will regain their hearing in a short amount of time.

Stenosis, exostoses and ossicular chain discontinuity can also cause conductive hearing loss. Because these conditions can be more complex to treat medically and current techniques are insufficient in treating all cases successfully, these types of hearing losses are considered permanent. Again these can be treated with implantable hearing devices. Assisted listening devices will also be important in these cases.

Mixed hearing loss

This is the condition that contains elements of both sensorial and conductive hearing loss. Treatment options can depend on the extent of the damage and whether the hearing loss is more conductive than sensorial.
