Hearing loss
Hearing loss most commonly occurs when the bundles of tiny hairs
within the inner ear become damaged. These tiny hairs are essential
for converting sound vibrations into the electrical signals which
the brain interprets as sounds. Over the years, however, attrition
of both the cells and their hair bundles leads to hearing loss. On
average, about 30 percent of those over 65, and about 50 percent of
those over 75, are affected in this way.
There are many causes of hearing loss but the most common,
presbyacusis, which is also known as age-related Sensorineural
Hearing Loss, occurs slowly as we age. The hearing normally
deteriorates as a result of exposure to loud sounds, experienced
throughout our lives. Presbyacusis usually affects both ears
equally and the hearing loss is most marked at higher
frequencies.
This damage to the hearing nerves accounts for approximately 95%
of all hearing losses and is generally permanent. It cannot be
treated medically but it can be remedied successfully with the use
of digital hearing aids.
A second kind of hearing loss, known as Conductive Hearing Loss,
occurs when sound is not being transmitted properly to the inner
ear due to a 'mechanical' problem of some kind. It is often the
result of damage or blockage in the outer or middle ear. In most
cases, conductive hearing problems can be corrected
medically.
There can also be elements of both a Sensorineural and a
Conductive hearing loss and this is known as a Mixed Hearing
Loss.
