Presbycusis

PRESBYCUSIS

Presbycusis is the loss of hearing that gradually occurs in most individuals as they grow older. The loss associated with presbycusis is usually greater for high-pitched sounds. For example, it may be difficult for someone to hear the nearby chirping of a bird or the ringing of a telephone. However, the same person may be able to hear clearly the low-pitched sound of a truck rumbling down the street.

Presbycusis most often occurs in both ears, affecting them equally. Because the process of loss is gradual, people who have presbycusis may not realize that their hearing is diminishing.

What are the symptoms of presbycusis?

With presbycusis, sounds often seem less clear and lower in volume. This contributes to difficulty hearing and understanding speech. Individuals with presbycusis may experience several of the following:

The speech of others seems mumbled or slurred.
High-pitched sounds such as "s" and "th" are difficult to hear and tell apart.
Conversations are difficult to understand, especially when there is background noise.
A man's voice is easier to hear than the higher pitches of a woman's voice.
Certain sounds seem annoying or overly loud.
