The writer wrote the passage to tell students to . A. join in clubs B. help teachers C. make less pollution D. clean schools C 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, rock music is also 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 important, constant loud noise can cause a loss of hearing. Scientists use a unit of measure called decibel to measure the loudness of a sound.
