There are many causes of hearing loss but the most common we come across as hearing aid audiologists is the general ageing process. Hearing loss is a natural consequence of getting older.
Our hearing starts to drop from our twenties and worsens from our thirties and forties. By the time we reach our eighties more than half of us suffer from significant hearing loss. Despite this a significant percentage of people with hearing loss are of working age due to other factors.
The next most common factor in hearing loss is exposure to excessive noise. We live in a noisy world and noise can come from our work or hobbies, such as using guns or listening to loud music at rock concerts, night clubs, discos and from stereos – with or without the use of headphones. The increasing use of portable MP3 players at levels so loud as to cause damage is increasing.
Hearing loss may also occur as a result of disease, infections or drugs. It may be inherited or be a result of physical damage to the ears or serious injuries to the head.
Hearing loss can either be conductive (related to the middle ear or ear drum) or sensorineural (related to the hearing nerve itself). Some people suffer from both, then we call it a mixed hearing loss.
