From Love To Harm
No doubt you have noticed a lot of people walking down the street with earphones on these days, listening to music. Sometimes it’s so loud, everyone gets to share it. Well, guess what? Doctors have discovered those people with earphones may be ruining their hearing. Mikel McCaving is a typical, video-game-playing, cell-phone-taking, music-obsessed-teenager. And he loves his iPod. Mikel: Pretty much every, every moment that I can fit it in, I try to listen to music. But when the volume goes up, so does the risk of hearing loss, dramatically. Brian Fligor: Noise incuced hearing loss develops insidiously. Audiologist Brian Fligor has found that personal stereo systems, like the iPod, can lead to significant hearing loss. He says there are two critical factors: how loud the music is, and how long you listen. When he tested my volume tolerance, I was safe at around 80 decibels, or about half way up the dial. But at decibel levels over 85, Fligor suggests no more than an hour a day with headsets outside the ears, and only 15 minutes with those inside. Fligor: For some types of inner earphones most certainly there is greater potential for danger. Kathy Peck(Expert): You know, if somebody can hear you system nest to you, if you’re on the bus or something, it’s too loud. It’s way too loud. And it doesn’t matter what type of music you enjoy. Your ears don’t discriminate. You can love Rock’n’Roll for lifetime, if you can just keep it down. 你一定注意到现在很多走在大街上的人都戴着耳机在听音乐。有时候音乐声音太大了，以致周围的人都可以听到。你知道这会有什么结果吗？医生研究发现，戴耳机听音乐可能会让人听力受损。 Mikel McCaving是一个典型的沉迷于电脑游戏、手机聊天、爱好音乐的少年。另外，他也钟爱他的iPod. Mikel:几乎每时每刻，只要有机会，我就会听音乐。 可人们一旦把音量调的过高，他们出现听力受损的可能性也显著增大。 Brian Fligor：由噪音引起的听力受损是在不知不觉中形成的。 听力病矫治专家Brian Fligor发现，各种随身听播放器，如iPod等，有可能导致人们听力显著下降。他说问题的严重性取决于两个重要因素：音乐播放的音量以及听音乐的时间。 当他给我进行音量忍受程度测试时，发现对我来说，80分贝左右的声音算是在安全范围内，也就是大概在刻度表一半以上的位置。Brian Fligor说，当声音超过85分贝的音量水平，如果把耳机戴在耳外，一天听的时间不能超过一小时；如果使用入耳式耳机，则不能超过15分钟。 Brian Fligor：毋庸置疑，某些插入式耳机对耳朵有更大的潜在危害性。 Kathy Peck（专家）：如果你在公交车或其他一些地方，你周围的人都能听到你的耳机播放的声音，那就说明你把音量调的太大了。音量太大了。 听力是否受损与你听的音乐类型无关，你的耳朵在这点上不会区别对待。 |
