Age-related hearing loss, known as presbycusis, affects most older adults to some degree. The most frequent cause of age-related hearing loss is the natural breakdown of nerve cells in the inner ear . Sound reaches the inner ear, but the breakdown of nerve cells prevents proper hearing. This is known as sensorineural hearing loss.
Age-related hearing loss can also be caused by age-related changes that may affect the eardrum or the bones of the middle ear, which affects how well sound can move into the inner ear. Long-term medical conditions, such as high blood pressure, heart disease, and diabetes, or other problems with blood movement (circulation), may also contribute to age-related hearing loss.
Age-related hearing loss usually affects both ears and may range from mild to severe. It may affect your hearing in the following ways:
- Speech sounds mumbled, and conversations are hard to understand, especially when there is background noise.
- Your ability to hear and distinguish high-pitched sounds is reduced. A man's lower-pitched voice may be easier to understand than a woman's higher-pitched voice.
- You hear ringing, roaring, hissing, or other sounds in your ears (tinnitus). Tinnitus may increase as your hearing loss gets worse.
If you have age-related hearing loss, you may not know it, because older people usually lose their hearing very slowly. Without knowing it, you may make small changes over time-turning up the TV volume, standing closer to a person who is speaking-that allow you to adapt to hearing loss. At some point, the loss may become so severe that these changes no longer work. Your family members or friends may be the first to realize that you cannot hear well.
There is no known way to reverse age-related hearing loss. But if you have age-related hearing loss, there are devices that can help you hear and communicate more easily, including hearing aids, telephone amplifiers, pagers, and email. It is also helpful to ask your family and friends to make adjustments when talking with you, such as speaking clearly and facing you so that you can better see their facial expressions and gestures.
