Passage Three Doctors have known for a long time that extremely loud noises can cause hearing damagc or loss. The noise can be the sound ofa jet aiphne or machines in factories or loud music or other common sounds at home and at work. A person only needs to hear the noise for a litle more than onc scond to be alected. An American scientist has found that using aspirin (阿斯匹林) can incrcease the temporary (暂时的) hearing loss or damage from loud noise. He did an experiment, using a number of male students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, and then he tested their bearing ability. He found that the students who were given four gams of aspirin a day for two days suffered much geater temporary bearing loss than those who did not use aspirin. The hearing loss was about two times as great.The scientist said millions of people in the United States use much larger amounts of aspinn than were used in the study. He sid these pcople face a serious danger of sufring hearing loss from loud noise.
