近20年来,全球噪声污染有增无减。在我国,城市噪声污染已经成为干扰人们正常生活的主要环境问题之一。2004年,对312个城市进行的区域环境噪声监测结果表明,属于严重污染的城市占0.3%,中度污染的占2.9%,轻度污染的占34.6%。严重污染和中度污染的城市比例比前两年虽有所下降,但总的污染范围有所扩大。研究表明,噪声污染不但影响人的听力,而且可导致高血压、心脏病、记忆力衰退、注意力不集中及其他精神疾病。
In the past 20 years, global noise pollution has been on the rise. In our country, urban noise pollution has become one of the major environmental problems that disturb people’s normal life. In 2004, the results of regional environmental noise monitoring conducted in 312 cities showed that 0.3% of the cities were seriously polluted, 2.9% were moderately polluted and 34.6% were slightly polluted. The proportion of heavily polluted and moderately polluted cities has dropped from the previous two years, but the total pollution area has expanded. Research shows that noise pollution affects not only human hearing, but also high blood pressure, heart disease, memory loss, inability to concentrate, and other mental illnesses.
