Hearing Damage Rises among Teens

Are you listening to me through headphones? Because here’s a sample of what might be harming the ears of teenagers.

你是否在用耳機(jī)聽(tīng)我說(shuō)話？這就是一個(gè)可能損傷青少年耳朵的例子。

Just kidding—the last thing we want to do is damage your hearing. But that might be happening to adolescents. According to a study in the Journal of the American Medical Association, adolescents show a significant increase in hearing loss since the early '90s.

說(shuō)笑的——損傷你的聽(tīng)力是我們最不希望的事。但聽(tīng)力損傷有可能正發(fā)生在青少年身上?！睹绹?guó)醫(yī)學(xué)協(xié)會(huì)學(xué)報(bào)》的一項(xiàng)研究表示，青少年的聽(tīng)力損傷自90年代初開(kāi)始明顯增加。

The study used two surveys. The first involved almost 3,000 adolescents tested between 1988 to 1994. The second involved 1,800 people tested in 2005 and 2006. There was a 31 percent increase in any kind of hearing loss in the second group versus the earlier one.

此研究進(jìn)行了兩次調(diào)查。第一次調(diào)查開(kāi)展于1988至1994年之間，有將近3000名青少年參與測(cè)試。第二次調(diào)查則開(kāi)展于2005至2006年之間，有1800名青少年參與測(cè)試。與第一次被調(diào)查人群相比，第二次被調(diào)查人群的各類(lèi)聽(tīng)力損傷上升了31%。

This problem affects millions of teens—one in five, according to the later survey. It can harm communication, social skills and education. The researchers don’t make causal links, though they caution that loud sound exposure from listening to music might be particularly significant to adolescents. The rise in hearing loss does correlate with a rise in MP3 players and their earbuds.

這個(gè)問(wèn)題影響了無(wú)數(shù)青少年——最新調(diào)查顯示有20%的青少年受到影響。聽(tīng)力損傷會(huì)阻礙交流、降低社會(huì)技能以及影響教育。盡管研究人員警告，對(duì)青少年聽(tīng)力損傷問(wèn)題而言，聽(tīng)音樂(lè)時(shí)喧鬧外放的聲音非常關(guān)鍵，但他們?nèi)晕创_定其中的因果關(guān)系。聽(tīng)力損傷的增加的確和MP3播放器以及耳塞式耳機(jī)使用增多有所聯(lián)系。

Speaking of which—check out these sounds.

說(shuō)到這里，聽(tīng)聽(tīng)這段音樂(lè)——
