Age-related hearing loss, or presbycusis, is the progressive hearing loss that occurs as people get older. With presbycusis, the hearing threshold is increased, especially at high frequencies and speech perception is decreased in noisy environments. In addition, presbycusis may have adverse effects on the cognitive, behavioral, and psychosocial functioning of the elderly. They may feel social isolation, depression, and loss of self-esteem. The pathophysiology of presbycusis is explained by age-related changes in the inner ear, the auditory system and the central nervous system. There is no single cause of presbycusis. It is a complex disease influenced by genetic, environmental, and psychosocial factors, as well as medical conditions. Hearing loss is one of the most common chronic conditions affecting the elderly. The population aged 65 years and older is now increasing at a rapid rate. Approximately 40% of people over 75 years of age are suffering from hearing loss. Because presbycusis is permanent and irreversible, there is no specific treatment to restore hearing loss. Because hearing loss in the elderly is closely related with quality of life, prevention and hearing rehabilitation programs using hearing aids are very important. In an aging society like Korea, an increase in social costs is inevitable for the welfare of the elderly. In particular, prevention and rehabilitation programs for hearing loss will play important roles in this perspective.
