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

Noise can be caused by many kinds of machines,such as motorcycles,jet planes,farm tractors (拖拉機(jī)）. Rock music is also a noise.

What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But,most importantly,constant(不斷的)loud noise can cause loss of hearing.

Scientists use a unit of measure called decibel (分貝） to measure the loudness of a sound. The sound of a quiet room,for example,measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at its high level(層次)causes great hearing loss.
