Description
Presbycusis is age-associated sensorineural hearing loss. Sensorineural hearing loss refers to dysfunction occurring in the inner ear, cochlea, or auditory nerve. This is contrast to conductive hearing loss, which refers to deficits in external sounds getting to the inner ear. One study of Medicare recipients aged 73 to 84 found hearing loss in 60%, and high-frequency hearing loss in 77%. Presbycusis is typically bilateral.
