Question

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 human, too.

People who work and live under noisy conditions usually become deaf(耳聾的). Today, however, scientists believe that 10% of workers in Britain are 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 plane 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（分貝） 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 people’s government is trying to solve not only air and water pollution problems but also the noise pollution problems.
