Presbycusis is the age-related hearing loss. It describes the gradual decline in hearing that comes with aging, often due to degeneration of the inner ear hair cells and auditory nerves, which typically starts with higher frequencies and can make understanding speech in noisy environments harder. Tinnitus, while it can accompany hearing loss, is the perception of ringing or buzzing and is not the loss itself. Cataracts affect vision by clouding the eye’s lens, and astigmatism is an eye refractive error. So the term that specifically means age-related hearing loss is presbycusis.
