Noise Pollution

Stop! Listen！ What do you hear? You may hear many different sounds. Some of those sounds may be noisy. Noise is loud or unwanted sound.

Noise can be caused by many kinds of machines ，such as motorcycles ， jet planes ， tractors (拖拉机)and so on. And ，to some people, rock bands also cause noise.

What happens to people living near noisy conditions? Doctors find that these people have trouble in sleepily. But most seriously, constant (持续的)loud noise can cause a loss of hearing.

Scientists measure the loudness of a sound by decibel (分贝).The bigger the number of decibel is, the noisier it will be. The sound of a quiet room, foe example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from the traffic and some rock bands can measure over 120 decibels. Noise at this high level causes the greatest hearing loss.
