老年性听力损失是最常见的听力疾病，老年性听力损失的英文是presbycusis，由两个希腊字组成：presby意思是老年；而cusis则意味着听力。老年性听力损失让人联想起许多和老年相关的疾病，比如老花眼便是一例年龄和感觉器官退化的问题，指老年人衰退下降的视力。
老年性听力损失是最常见的听力疾病，老年性听力损失的英文是“presbycusis”，由两个希腊字组成：“presby”意思是“老年”；而“cusis”则意味着“听力”。老年性听力损失让人联想起许多和老年相关的疾病，比如“老花眼”便是一例年龄和感觉器官退化的问题，指“老年人衰退下降的视力”。
Age-related hearing loss is the most common listening diseases, age-related hearing loss English is "presbycusis", consisting of two Greek words: "presby" means "old"; and "CUSIS" means "listening". Age-related hearing loss is reminiscent of many age-related diseases, such as "presbyopia" is the problem of a healthy age and sensory degradation, refers to "the elderly poor eyesight decline".
老年性听力损失表现为轻到中度的感音神经性听力损失，它是当今社会目前最常见的听力损失类型之一。美国约80%的听力损失都是老年性听力损失。随着婴儿潮出生的人口老龄化，人口统计学显示存在有年龄不断增长的趋势，人口的平均年龄也在增加。因此，我们可以预测到将来老年性听力损失患者的数目将急速增加。加拿大卫生部将老年性听力损失排在诸多慢性听力损失首榜。
Age-related hearing loss showed mild to moderate sensorineural hearing loss, it is one of the most common type of hearing loss in today's society. About 80% America hearing loss are age-related hearing loss. With the baby boomer population aging, population statistics show that there are age increasing, the average age of the population is on the increase. Therefore, we can predict the future number of age-related hearing loss patients will increase rapidly. Health Canada would age-related hearing loss in many chronic hearing loss in the first list.
大多数老年性听力损失导致轻到中度的感音神经性听力损失，都是由外毛细胞损伤引起。通常为低频轻度、高频中度的吃力损失。美国著名听力学家Jerger等人在1993年比较了50到89岁之间的男性和女性的听力损失图。他们发现一般来说男性比女性有更陡峭的听力损失，高频重些，低频轻些。对于女性来说，低频听力损失更甚的原因可能是血管纹的退化影响到了耳蜗毛细胞的血供。男性高频听力损失严重的原因可能为工作相关性噪声听力损失（NIHL）和老年性听力损失。
Light to moderate sensorineural hearing loss that causes most age-related hearing loss, are caused by outer hair cells injury. Usually mild, moderate difficulty of high frequency low loss. USA famous hearing scientist Jerger et al compared with between 50 to 89 years for men and women of hearing loss in 1993. They found that generally men than women are more steep hearing loss, high frequency and low frequency heavier, lighter. For women, because of low frequency hearing loss even may be the stria vascularis degradation affects the blood supply of the hair cells in the cochlea. Cause of male high-frequency hearing loss serious potential for noise hearing loss of job relevance (NIHL) and age-related hearing loss.
噪声听力损失其实不能完全和老年性听力损失分开，许多男性的老年人由于早期从事噪音相关工作，会加速由于听觉系统衰老引起的听力损失，同样的，噪声听力损失也会引起外毛细胞的损伤，特别是对那些持续暴露于噪声环境下的人。然而，根据Borg，Canlon，Engstrom（1995）和Killion（1997c）等人的研究，突发性脉冲噪声，如枪击声，会引起内、外毛细胞的同时损伤，便会造成噪声环境下对言语理解的困难；但实际上内毛细胞传输大多数的声音信息到大脑。如果内毛细胞受损，传到大脑的信息就会“混淆”起来，导致噪声下的言语分辨困难。
Noise hearing loss is not completely separated and age-related hearing loss, many men of the elderly because of early in the noise related work, will accelerate the auditory system due to aging induced hearing loss, the same, the noise hearing loss can also cause loss of outer hair cells, especially for those with continued exposure to noise environment. However, according to Borg, Canlon, Engstrom (1995) and Killion (1997c) et al., sudden impulse noise, such as shot noise, can cause the inner, outer hair cell injury, will cause the noise environment of speech comprehension difficulties; but the inner hair cell transmission of voice information most to the brain. If the inner hair cell damage, to the brain's information will be the "confusion", resulting in noise speech discrimination.
