One Billion Young People Risk Hearing Loss From Loud Music

十億年輕人因為聽大聲的音樂面臨失去聽力的危險

From VOA Learning English, this is the Health and Lifestyle report.

美國之音這里是健康和生活方式報道。

One billion teenagers and young adults around theworld risk losing their hearing by listening to loud music. This is according to the World Health Organization. The U.N. agency is asking young people to turn down thevolume to prevent irreversible damage to their hearing.

根據(jù)世界衛(wèi)生組織的調查，全世界有十億的青少年因為聽音樂開很大聲，面臨失去聽覺的危險。世衛(wèi)組織要求孩子們關小音樂的聲音，來阻止這種對耳朵不可逆性的損傷。

Few things get the blood pumping like good music.Many people believe louder is better if you are listeningto rock and roll.

沒有幾件事情像好音樂一樣可以使血液興奮。許多人認為如果聽搖滾的話，聲音越大越好。

But experiencing really loud music, even really goodmusic, can have a serious effect on your hearing.

但是聽過很大聲的音樂，甚至真的是好音樂后，你的聽覺系統(tǒng)會受到嚴重影響。

Dr. Shelley Chadha is a specialist on hearing damagefor the World Health Organization. Dr. Chadha says that the cells we use to hear, called sensory cells, canbe permanently damaged by loud sounds that happen over a long period of time, or are prolonged, and happen regularly, or are habitual.

Shelley Chadha博士是世衛(wèi)組織聽覺傷害方面的專家。Chadha博士說我們通常用來聽的細胞稱為感覺細胞，它會因為通過長時間聽很大的聲音，或者定期的或者說習慣性的很大的聲音，遭到永久性的損傷。

"When this exposure is particularly loud or prolonged or habitual, the sensory cells are damaged permanently leading to irreversible hearing loss."

當聲音特別大，或者長期習慣性接觸，感覺細胞就會遭到嚴重損傷，導致不可逆的聽力喪失。

Studies in middle-and high-income countries show nearly 50 percent of teenagers and young adults aged12 to 35 years listen to unsafe levels of sound. They are listening on theirpersonal audio devices as well as at concerts, nightclubs and otherentertainment places.

在中等和高收入國家的調查顯示，幾乎50%的12歲到35歲之間的年輕人會把音樂的聲音調到不安全的級別。他們通過自己的音樂設備或者音樂會，夜店以及去其他的娛樂場所聽音樂。

But what is an unsafe level of sound?

但是什么是不安全級別的聲音?

The WHO says there can be many kinds of unsafe levels of sound. Itdepends on how loud the sound is and how long you listen to it. Unsafe can mean noise levels of 85 decibels for eight hours a day or 100 decibels for just15 minutes.

世衛(wèi)組織表示有許多的不安全聲音。取決于聲音有多大，你聽了多長時間。一天聽8小時85分貝的聲音，或者聽15分鐘100分貝的聲音都意味著那是不安全的噪音。

Dr. Chadha told VOA when the intensity of sound increases by only three decibels, safe listening time goes down by half.

Chadha博士告訴美國之聲，聲音強度增加3個分貝時，安全的聽力時間要下降一半。

"If a person takes a subway to go from one place to the other for half an hourin the morning and a half an hour in the evening, and every day has to turn upthe volume on his device because there is so much of noise of the train andeverything around, and is listening to - let us say 100 db (decibels) for onehour every day, his hearing is going to get irreversibly damaged in a fewyears, in a couple of years time, for sure."

“如果一個人從一個地方做地鐵到另一個地方，早上半小時，晚上半小時，每天在地鐵上他不得不把他的耳機聲調很大聲，因為地鐵上的噪音很大，比如他每天聽1小時100分貝的聲音，那么在幾年之內他的聽覺系統(tǒng)會遭到不可逆的損傷，這是一定的。”

Simple ways to prevent irreversible hearing loss

幾個簡單的辦法幫助阻止不可逆的聽力喪失。

Dr. Chadha says there are simple measures to protect people from unsafesound levels. She says young people who wear earplugs during concerts canenjoy music at 90 decibels as much as they can at 110 decibels. But shead mits that earplugs may not look very cool.

Chadha博士說有幾個簡單的辦法可以保護人們在安全級別內。年輕人在聽音樂會時帶著耳塞盡可能聽90分貝，但是耳塞可能看起來不那么酷。

"The fact that earplugs may look un-cool may be true today, but if there is achange in behavior that may not necessarily be true in the future and wearingearplugs may actually be cool."

“事實上現(xiàn)在帶耳塞看起來確實不怎么酷，但是如果我們的行為觀念發(fā)生變化后，將來帶著耳塞聽音樂，可能看起來會非常酷。”

A common sense suggestion is to turn down the volume on your personalaudio devices. The WHO also advises young people to limit their use of suchdevices to less than one hour a day. It reminds people to use their technologyto stay safe. Smart phone apps can help to monitor safe listening levels.

一個大眾化的建議就是把你音樂設備的聲音調小。世衛(wèi)組織也建議年輕人每天限制聽這種設備在1小時之內。這使人們聯(lián)想到運用科技保護自己。智能手機apps可以幫助監(jiān)測安全的聲音級別。

The U.N. agency estimates 360 million people suffer hearing loss linked tomany causes, including noise, genetic conditions, infectious diseases and aging. It notes half of all cases of hearing loss are avoidable.

世衛(wèi)組織測試了3600萬遭受聽力喪失人的誘因，包括，噪音、形成條件、傳染性疾病和年齡問題。它表明一半聽力喪失的誘因都是可以避免的。
