In today's world, almost everyone knows that air pollution and water pollution are bad<br />for people's health. However, not all the people know that noise is also a kind of pollution,<br />and it is bad for our health too. People who work and live under noisy environments usually<br />have poorer hearing. Many people who live near airports become deaf. Recently it was<br />discovered that many young people in America could hear no better than 65 year old people,<br />for these young people like to listen to pop music, and most of pop music is a kind of<br />noise. Noise will make people's life difficult and unpleasant, or make people ill, or even drive<br />people mad. In China, people are trying to solve not only the problems of air and water pollution,<br />but also the problem of noise pollution.
