cause early damage to the ears.

time.Some degree of hearing loss is observed in over half of people

who are above the age of 60. This deafness is age-related.

• Genetics: Your genetic can be also a reason for ear damage. When

looking at the genetics of deafness, there are 2 different forms,

syndromic and nonsyndromic.
