[00:00.98]Exercise 4 Listen to the scond part of
[00:04.22]the radio programme.Take notes on the following
[00:08.05]So,it's very important to control noise
[00:10.78]pollution, isn't it?
[00:11.81]That's right.As I said,
[00:13.38]noise pollution is unpleasant for us all.
[00:16.52]It can cause stress and loss of sleep
[00:19.18]and can also damage our hearing.
[00:21.97]Take car horns for example.
[00:24.87]Experts say that only 40 minutes
[00:27.61]of exposure to a car horn would damage our
[00:30.61]hearing permanently.So you see,
[00:33.26]noise pollution really can affect
[00:35.45]people's lives.
[00:37.00]How can noise pollution be controlled?
[00:39.52]Actualy,noise pollution isn't hard to control.
[00:42.73]There are some relatively simple methods
[00:44.97]that the government has started using
[00:47.16]to reduce noise pollution in our cities.
[00:49.89]For example, there are plans to improves public
[00:53.12]transport so that the number of cars
[00:55.61]on the roads will be reduced.
[00:57.71]There are also plans to install soundproof
[01:00.95]windows in buildings which face onto roads.
[01:04.52]Another way to reduce noise pollution
[01:07.04]is to build main roads,
[01:08.62]industrial areas and shopping malls
[01:11.06]away from places like schools,
[01:13.04]hospitals and residential areas
[01:15.90]where people need peace and quiet.
