Age-related hearing loss
Age-related hearing loss, or presbycusis, is the slow loss of
hearing that occurs as people get older.
Alternative Names
Hearing loss - age related; Presbycusis
Causes, incidence, and risk factors (காரணங்கள்)
Tiny hair cells inside your inner ear help you hear. They pick
up sound waves and change them into the nerve signals that the brain interprets
as sound. Hearing loss occurs when the tiny hair cells are damaged or die. The
hair cells do not regrow, so most hearing loss caused by hair cell damage is
permanent.
There is no known single cause of age-related hearing loss. Most
commonly, it is caused by changes in the inner ear that occur as you grow
older. Your genes and loud noise (such as from rock concerts or music
headphones) may play a large role.
The following factors contribute to age-related hearing loss:
·
Family
history (age-related hearing loss tends to run in families)
·
Repeated
exposure to loud noises
· Smoking
(smokers are more likely to have such hearing loss than nonsmokers) (ஸ்மோகிங்)
·
Certain
medical conditions such as diabetes
·
Certain
medicines
Symptoms (அறிகுறிகள்)
Loss of hearing often occurs slowly over time.

Talk to you health care provider if you have any of these

alarm) and psychological (social isolation) problems.
The hearing loss may lead to deafness.
