10．In today's world，almost everyone knows that air pollution and water pollution are harmful to people's health．However，not all the persons know that noise is also a kind of pollution，and that is harmful to human health，too．
People who work and live under noisy conditions usually become deaf．Today，however，scientists believe that 10percent 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（织） 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 persons，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 85decibels（分贝） can cause deafness．Now the governments in many countries have made laws to control noise and make it less than 85decibels．
In China，the government is trying to solve not only air and water pollution problems but also noise pollution problems
