The World Health Organisation (世界卫生组织) warns that a billion teenagers and people in their twenties and thirties are damaging their hearing with loud music. It says nearly half the young people in richer countries risk hearing loss because of listening to music at "unsafe" levels. Loud music in nightclubs, bars and at sporting events increases the risk. The WHO says a safe limit is to listen to music for an hour a day. The WHO head for injury prevention said: "What we're trying to do is raise awareness of an issue that is not talked about enough." He said people can prevent hearing loss.
世界卫生组织警告说，有十亿的青少年和人们在自己二十几岁和三十几岁的时候用喧闹的音乐损坏听力。它 说发达国家将近一半的年轻人面临听力损伤的危险，因为他们听的音乐不在一个安全水平上。夜总会，酒吧和体育中心的喧闹的音乐都会增加听力损伤的风险。世界卫生组织称，安全界限就是一天听一个小时的音乐。世界卫生组织总部的伤害预防中心称：“我们所要做的是引起人们对一件并不太重视的事情的注意。”他说，人们可以预防听力损失。
Turning the sound down and listening to music for less than one hour a day could save many people's hearing. However, the WHO head also said that, "even an hour can be too much if the sound is too loud". A biomedical researcher explained how noise can damage ears. He said: "Loud sounds damage your hearing by killing off thousands of little hair cells in the inner ear. The cells feel different…sounds through vibration…but they are very fragile and if they vibrate too much due to loud sounds for too long, they get damaged and die." He warned that if they die, they never regrow.
把声音调低和一天听不到一个小时的音乐可以拯救很多人的听力。然而，世界卫生组织总部称：“假如声音很吵闹，即使一个小时也太多了。”一个生物医学研究员解释了多吵会损伤耳朵。他说：“吵闹的声音通过杀死成千上万的内耳毛细胞来损伤你的听力。这些细胞通过震动感觉不同的声音……但是它们非常脆弱，如果由于太长时间听吵闹的声音而震动太久，它们会受到损害而死去。”他警告说，假如这些细胞死去了，它们不能再生。
