Why does presbycusis become more common after age 60?

Presbycusis is the gradual decline of hearing function associated with the aging process. It becomes more common after age 60 primarily due to the progressive loss of [cochlear hair cells].12

This degeneration typically begins at the basal end of the organ of Corti, which leads to a reduction in the ability to perceive high-frequency sounds. As these cells are lost over time, individuals experience increasing difficulty in hearing high-pitched tones and understanding conversation. While this decline is a natural part of aging, it occurs at different rates among the population.132

It is important to distinguish this age-related loss from other remediable conditions that may affect hearing in older adults, such as accumulated earwax, middle-ear inflammation, or [stirrup fixation]. If you are experiencing hearing difficulties, a physician should evaluate your condition to rule out these treatable impairments.12
