在吵杂拥挤的地铁、街道、办公室里如何营造一个属于自己的空间？很多人的办法就是带上耳机播放自己喜欢的音乐。不过长期使用耳机或者播放音量过大，都是会影响听力的。
世界卫生组织发布数据显示，全球有超过10亿12到35岁之间的年轻人，正面临无法逆转的听力受损风险，个人音频设备音量过大，例如用手机听音乐，是造成风险的重要原因。
面对如此严峻的形势，世界卫生组织和国际电信联盟联合发布了针对智能手机和音频播放器等个人音频设备的新标准，希望用户和硬件制造商可以重视对听力的保护。

Turn it down! Millennials' music habit puts their hearing at risk: U.N.
① A generation of music-lovers are damaging their hearing with audio players that do not limit dangerously high noise levels, the U.N. health agency said.
② Already 466 million people worldwide have debilitating hearing loss and the figure is expected to nearly double to 900 million, or one in every 10 people by 2050, according to the World Health Organization (WHO).
③ Over 1 billion young people are at risk of hearing loss simply by listening regularly to music through their headphones over their devices.
④ The WHO is launching new international standards, in an effort to urge manufacturers and regulators to ensure smartphones and other audio players safer for listening.
⑤ "Our effort through this standard is really to empower the user to make the right listening choice or take the risk of developing hearing loss and tinnitus a few years down the line," Dr. Shelly Chadha of the WHO said.
⑥ The WHO is also looking at volume levels in places such as nightclubs and sporting arenas. It has some guidelines but they are not widely implemented.
