By National Institute of Deafness and Other Hearing Disorders. Presbycusis is the loss of hearing that gradually occurs in most individuals as they grow older. Hearing loss is a common disorder associated with aging. About 30 to 35 percent of adults between the ages of 65 and 75 years have a hearing loss. It is estimated that 40 to 50 percent of people 75 and older have a hearing loss. The loss associated with presbycusis is usually greater for high-pitched sounds.
