Question

【题目】 Do you often listen to music at loud volumes（音量）? You should know that this habit is bad for your hearing, according to the World Health Organization (WHO).

Over 1 billion young people have problems in listening because they listen at loud volumes for a long time, WHO said. Listening to music or watching a TV show at loud volumes can harm your hearing.

The United Nations has standards for safe listening. It is not safe to listen to sounds that are louder than 85 decibels (分贝) for eight hours or 100 dB for 15 minutes. The sound of a busy road is about 85 dB and the sound of a rock concert can be about 100 dB.

Loud noise is harmful to the inner ear. Most of us are born with about 16,000 hair cells (听毛细胞) in our inner ears. These cells detect (探测) sounds. However, listening to loud noise for a long time can make these cells work too hard and make some of them die. This is why people have hearing loss.

Some people might think that their music isn’t all that loud. But this can depend on where you are. For example, if you are in a noisy place like the subway, you might turn up your music too loud without realizing it. Later, when you listen to it at the same volume in a quiet place, you might feel uncomfortable.

WHO said the “safe level” for most sound is below 80 decibels for up to 40 hours a week. A level of 80 decibels is roughly equal to the noise of a subway.

B. Because it can cause hair cells in the inner ear to die.

本文主要讲述了听大音量音乐的习惯对听力有害。世界卫生组织称，超过10亿的年轻人在听力方面存在问题，因为他们长时间大声聆听。联合国有安全聆听标准。听八十小时大于85分贝或15分钟大声100分钟的声音是不安全的。长时间聆听大声的声音可能会使这些细胞工作太猛，并使其中一些细胞死亡。这就是人们听力损失的原因。
