Hearing loss is common. In New Zealand almost 1 out of 6 people have some form of hearing loss in one or both ears. It can be present at birth or acquired at any age.
There are two types of hearing loss:
When something prevents the sound wave vibrations entering the inner ear it is called a conductive loss – the sound wave conduction is hindered. Generally this type of hearing loss is medically correctable
When the hearing cells in the cochlea cannot pick up or transmit information to the brain it is called a sensorineural loss. This type of hearing loss is most often permanent. Some causes are listed below:
This results when there is a combination of conductive and sensorineural hearing loss present.
