As people age, the likelihood of hearing loss increases due to presbycusis, a gradual degenerative change in the inner ear and auditory pathways. By about 85 years old, roughly half of individuals have some degree of hearing impairment, making this age group the point where prevalence crosses the 50% mark. This reflects that hearing loss becomes a common issue in the oldest adults, often bilateral and sensorineural, affecting communication, safety, and quality of life. While some individuals in this age range may have little or no loss and others more severe loss, the approximate 50% figure is the best general estimate for this group.
