It's becoming more and more of a problem worldwide, isn't it?
Yes,I quite agree.But noise pollution is generally only a problem in urban areas. This is because of increasing industrialization transport,and larger urban populations.
Can you talk in more detail about these causes of noise pollution in our cities?
Certainly. Noise pollution in our cities comes from many sources. Traffic, aircraft, railways and factories produce huge amounts of noise pollution but a lot of noise pollution also comes from people. As urban populations grow, people are forced to live closer to each other and stereo systems, television sets, ari conditioners and pets can all be sources of noise pollution.
What are the effects of noise pollution? Noise pollution can have very serious effects.
Most people don't realize it but continued noise can actually damage our hearing. Another important factor is stress. Annoying sounds increase stress levels and can cause us to fell impatient and unhappy. They can also stop us from sleeping properly.These negative effects can have a significant impact on how well we concentrate at work, so noise pollution can affect productivity.
