There are many
causes of hearing loss or deafness but
mainly it can be divided into two
categories: Conductive hearing loss (CHL)
that occurs due to some mechanical
problem in the external or middle ear.
Fluid in the middle ear can cause CHL
and Sensorineural hearing loss (SNHL)
that results from a dysfunction of the
inner ear. People who have both forms
of hearing loss are said to have mixed
hearing loss. Ear infections are the
most common cause of temporary hearing
loss in children. Excessive wax in the
ear can also be lead to hearing loss.
Hearing loss or deafness can be
Genetic, Congenital, Infectious,
Traumatic, Toxic, Age-related and
Occupational. Symptoms of hearing loss
include: difficulty in hearing during
conversation, frequent asking to
others to speak loud or to repeat what
they have said, difficulty in hearing
on telephone, not getting enough
sounds or voices of people around. In
children symptoms of congenital
deafness can be identify when they do
not respond to sounds or at the
learning stage when they start
learning to speak. It is always
advisable to prevent hearing loss than
treating it after "the damage is
done." |
