Some forms of hearing loss can be inherited. Not all inherited forms of
hearing loss take place at birth, however; some can show up later in life. For
example, otosclerosis, which is thought to be a hereditary disease, disrupts
hearing later in life as an abnormal growth of bone prevents structures within
the ear from working properly. Typically, hearing loss caused by otosclerosis
doesn’t begin until 10 to 30 years of age.
