Around half of people over the age of 75 have some amount of hearing loss; however, half of seniors can hear well. Why do some people have hearing loss while others don’t? Let’s investigate.
In general, there are two main types of hearing loss: sensorineural hearing loss, which is usually permanent, and conductive hearing loss, which can often be reversed with proper treatment.
For babies born with hearing loss, around half of the cases are caused by genetics. For age-related hearing loss, estimates suggest that anywhere from 35-55% of cases may be related to genetic factors.
