Age-related hearing loss
Definition:
Age related hearing loss is a progressive loss of the ability to hear high frequencies, which occurs as people get older. Alternative Names:

Causes, incidence, and risk factors:
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.
