There are 3 general types of hearing loss
Conductive hearing loss
This occurs when the eardrum, hones an membranes transmit vibrations to the cochlea improperly. Causes include traumatic head injury, congenital defects, wax occlusion or blockage, and middle and outer ear infections.
Sensorineural hearing loss
This is characterised by functional deterioration of the cochlea. Causes include the ageing process and excessive exposure to loud noise.
Mixed hearing loss
This involves a combination of both conductive and sensorineural hearing loss.
