What causes Presbycusis?
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) Certain medical conditions such as diabetes Certain medicines </s>
