Age-related hearing loss

Age-related hearing loss (presbycusis) involves a progressive loss of hearing, beginning with high-frequency sounds such as speech. It is unknown whether a specific cause such as noise trauma leads to presbycusis, but there appears to be a genetic predisposition.

Age-related hearing loss tends to occur in families. The disorder occurs in about 25% of people aged 65 to 75 and in 70% to 80% of those over age 75.
