[00:00.40]It's becoming more and more of a problem
[00:02.99]worldwide,isn't it?
[00:04.33]Yes,I quite agree.
[00:06.27]But noise pollution is generally
[00:08.19]only a problem in urban areas.
[00:10.79]This is because of increasing industrialization
[00:14.29]transport,and larger urban populations.
[00:18.18]Can you talk in more detail about these
[00:20.65]causes of noise pollution in our cities?
[00:23.18]Certainly. Noise pollution in our cities
[00:25.54]comes from many sources.
[00:27.44]Traffic, aircraft, railways
[00:30.33]and factories produce huge amounts
[00:32.68]of noise pollution
[00:34.37]but a lot of noise pollution also
[00:36.58]comes from people.
[00:38.84]As urban populations grow,
[00:40.94]people are forced to live closer to each other
[00:43.71]and stereo systems,television sets,
[00:46.61]ari conditioners and pets can all be sources
[00:49.89]of noise pollution.
[00:51.74]What are the effects of noise pollution?
[00:55.09]Noise pollution can have very serious effects.
[00:58.42]Most people don't realize it
[01:00.53]but continued noise can actually
[01:02.68]damage our hearing.
[01:04.32]Another important factor is stress.
[01:07.25]Annoying sounds increase stress levels
[01:10.02]and can cause us to fell impatient and unhappy.
[01:13.97]They can also stop us from sleeping properly.
[01:17.37]These negative effects can have a significant
[01:20.19]impact on how well we concentrate at work,
[01:23.77]so noise pollution can affect productivity.
