Life gets noisier every day and very f people can be free from noise of some kind or another. W you live in the centre of a modern city or a village far away, the chances that you will be disturbed by planes, cars, radios are almost everywhere. We seem to be used to noise, too. Some people feel quite lonely w background music while they are working.
Tests have s that total silence can be very frightening experiences. However, some people enjoy listening to pop music which is very l , and this can do harm to their ears. The noise level in some places is far above the usual s level for heavy industrial(工业) areas.
One recent report about noise said that a a lot of people say that any noise disturbs their attention, only a sudden c in the level of noise really affects people’s attention. It goes on to say that a background noise, which doesn’t change too much, may even help people to pay attention.
