Question

【題目】 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 (分貝) 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 (聽毛細(xì)胞) in our inner ears. These cells detect (探測(cè)) 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.

【2】The sound level of a busy road is about _____.

A. 80 dBB. 85 dB

C. 100 dBD. 115 dB

【3】Why can listening to loud music cause hearing problems?

A. Because it puts our brains under great pressure.

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

C. Because it prevents our ears from resting.

D. Because it allows people to get used to listening to loud sounds.

【4】What can we get from the last paragraph?
