| definition |
Presbycusis, or age-related hearing loss, is the cumulative effect of aging on hearing. It is a progressive and irreversible bilateral symmetrical age-related sensorineural hearing loss resulting from degeneration of the cochlea or associated structures of the inner ear or auditory nerves. The hearing loss is most marked at higher frequencies. Hearing loss that accumulates with age but is caused by factors other than normal aging is not presbycusis, although differentiating the individual effects of distinct causes of hearing loss can be difficult. 临床上将老年开始出现的，双耳对称的，渐进性的神经性耳聋称为老年性耳聋，人体随着年龄增长会出现一系列衰老现象，老年性耳聋是因为听觉系统衰老而引发的听觉功能障碍。根据听力学的研究，男性约从45岁以后开始出现听力衰退，女性稍晚，随着人类寿命的延长，老龄人口的增多，老年人耳聋的发病率也有所增加。 Gradual bilateral hearing loss associated with aging that is due to progressive degeneration of cochlear structures and central auditory pathways.
