Noise(噪音)
Noise
ife gets noisier every day and very few people can be free from noise:of some sort or another. It doesn't matter where you live in the middle of a modern city, or a faraway village the chances are that you'll be disturbed by jet airplanes, transistor radios, oil-powered engines, etc. We seem to be getting used to noise, too.
Some people feel quite lonely without background music while they're working. Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums.
The noise level in some discos is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration suggested that although lots of people say that noise disturbs their concentration, what really influences their ability to concerttrate is a change in the level of noise. It goes on to say that a background noise which doesn't change too much (music, for
example) may even help people to concentrate.
噪音
生活日益嘈雜，幾乎沒有人能夠擺脫各種各樣的噪音。不論你住在哪里——發(fā)達城市的中心，還是遙遠的小村莊——都會受到噴氣飛機、晶體管收音機和汽油發(fā)動機的
干擾。而我們也似乎越來越對這些噪音感到無所謂了。
有人感覺工作時沒有背景音樂會非常孤單�？茖W(xué)試驗顯示，完全安靜的環(huán)境對人類來說是非�？膳碌�。但是，有些人喜歡聽聲音很大的流行音樂，這對人的耳膜傷害很大。一些迪斯科舞廳的噪音強度甚至遠遠超過重工業(yè)地區(qū)的一般安全標(biāo)準(zhǔn)。
最近，一項有關(guān)噪音與注意力的報告顯示，雖然很多人抱怨噪音使他們集中無法集中精力，而事實上真正影響他們集中注意力的是噪音強度的變化。報告還顯示，起伏變化不大的背景音(例如，音樂)甚至可以幫助人們集中注意力。
