Different Types of Hearing Loss

There are two main types of hearing loss.

The first type happens when there is a problem in the inner ear, usually in the cochlea (the part of the ear that turns sound into signals the brain can understand). This type is called sensorineural deafness. It is permanent.

Sensorineural hearing loss can be:

  • mild

  • moderate

  • severe

  • profound

A child may have different levels of hearing loss in each ear. Very few children are totally deaf.

The second type of hearing loss happens when sound cannot pass well through the outer or middle ear. This means sound does not reach the cochlea and the auditory nerve clearly. The most common cause is a build‑up of fluid in the middle ear, often called glue ear. This type of hearing loss is called conductive deafness. It is the most common type of hearing loss in children.

Conductive hearing loss often changes from day to day and is usually temporary.
