Cut music to 'an hour a day' - WHO
世卫组织:每天听音乐别超一小时


世界卫生组织日前建议,为了保护听力健康,每天听音乐的时间不应该超过一个小时。

有数据显示,有11亿青少年因为听音乐的时间太久且音量过大而使自己的听力健康处于风险当中。这些“噪声”的来源,主要是MP3等个人音频设备,音乐会和酒吧等。

数据还显示,有4300万年龄在12-35的人,听力出现损伤。而在发达国家和中等收入的国家中,几乎有一半的该年龄段青少年,成天“泡”在耳机中。

People should listen to music for no more than one hour a day to protect their hearing, the World Health Organization suggests.

It says 1.1 billion teenagers and young adults are at risk of permanently damaging their hearing by listening to "too much, too loudly".

It said audio players, concerts and bars were posing a "serious threat".

WHO figures show 43 million people aged 12-35 have hearing loss and the prevalence is increasing.

In that age group, the WHO said, half of people in rich and middle-income countries were exposed to unsafe sound levels from personal audio devices.

Meanwhile 40% were exposed to damaging levels of sound from clubs and bars.

The proportion of US teenagers with hearing loss went from 3.5% in 1994 to 5.3% in 2006.

WHO v The Who

Dr Etienne Krug, the WHO's director for injury prevention, told the BBC: "What we're trying to do is raise awareness of an issue that is not talked about enough, but has the potential to do a lot of damage that can be easily prevented."

The full report argued: "While it is important to keep the volume down, limiting the use of personal audio devices to less than one hour a day would do much to reduce noise exposure."

Dr Krug said that a good ambition aim: "That's a rough recommendation, it is not by the minute, to give an idea to those spending 10 hours a day listening to an mp3-player.

"But even an hour can be too much if the volume is too loud."
