     In today's world, almost everyone knows that air pollution and water pollution are harmful to people's

health. However, not all know that noise is also a kind of pollution, and that is harmful to humans, too.

     People who work and live under noisy conditions usually become deaf. Today, however, scientists

believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of

the workers who print newspapers and books, and who weave cloth become deaf. Quite a few people

living near airports also become deaf. Recently it was discovered that many teenagers in America could hear no better than 65-year-old people, for these young people like to listen to "pop" music and most of

"pop" music is a kind of noise. Besides, noise produced by jet planes or machines will make people's life

difficult and unpleasant, or even make people ill or even drive them mad. It is said that a continuous noise

of over 85 decibels can cause deafness.

     Nowadays the governments in many countries have made laws to reduce or control noise and make it

less than 85 decibels. In China, the government is trying to solve not only air and water pollution problems but also the noise pollution problem.
