Sensori-neural
Hearing Loss:
Sensori-neural hearing loss results from problems in the inner ear.
This type of hearing loss is most often the result of damage to
the tiny hair cells in the Cochlea. Once these hair cells have
been damaged they cannot be repaired or replaced. The only
treatment option is the use of amplification.
Everybody loses these tiny hair cells in the cochlea throughout
their life, and gradually their hearing becomes less acute. This
is process is called Presbyacousis, which is Greek for "Old
Hearing".
However, these hair cells can also be damaged by excessive noise.
As a result of prolonged exposure to high intensity noise either
from the work environment or from listening to loud music.
Noise induced hearing
impairment is the leading cause of hearing loss and is becoming more
common even with the efforts of OSHA.
You can also suffer from sensori-neural hearing loss from disease or if you have used
certain
drugs.
Hearing impairment may also occur if your mother has had rubella
(German measles) during pregnancy, or if your birth weight was
low.
Hearing impairment can also be inherited and finally you may lose
your hearing ability due to head/ear injuries.
With very few exceptions sensori-neural hearing loss is permanent
and individuals cannot regain their hearing. Most people with
sensori-neural hearing loss find
hearing aids very helpful.
