med_catPresbycusis (also spelled presbyacusis, from Greek presbys "old" + akousis "hearing"[1]), or age-related hearing loss, is the cumulative effect of aging on hearing.
It is a progressive and irreversible bilateral symmetrical age-related sensorineural hearing loss resulting from degeneration of the cochlea or associated structures of the inner ear or auditory nerves.
The hearing loss is most marked at higher frequencies.
Hearing loss that accumulates with age but is caused by factors other than normal aging (nosocusis and sociocusis) is not presbycusis, although differentiating the individual effects of distinct causes of hearing loss can be difficult.
