The gradual hearing loss that occurs as you age (presbycusis) is a common condition. An estimated one-quarter of Americans between the ages of 65 and 75 and around three-quarters of those older than 75 have some degree of hearing loss.

Over time, the wear and tear on your ears from noise contributes to hearing loss by damaging your inner ear. Doctors believe that heredity and chronic exposure to loud noises are the main factors that contribute to hearing loss. Other factors, such as earwax blockage, can 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 quieter, less distinct sounds. You and your doctor or hearing specialist can deal with hearing loss by taking steps to improve what you hear.
