Hearing loss that occurs gradually as you age (presbycusis) is common. About one-third of people in the United States between the ages of 65 and 75 have some degree of hearing loss. For those older than 75, the number of people with some hearing loss is almost 1 in 2.
Doctors believe that heredity and chronic exposure to loud noises are the main factors that contribute to hearing loss over time. Other factors, such as excessive earwax, can temporarily prevent your ears from conducting sounds as well as they should.
You can't reverse hearing loss. However, you don't have to live in a world of muted, less distinct sounds. You and your doctor or hearing specialist can take steps to improve what you hear.
