Too high a price? Part-2
Burglar alarms going off at any time of the day or night serve only to annoy passers-by and actually assist burglars to burgle. Car alarms constantly scream at us in the street and are a source of profound irritation. A recent survey of the effects of noise revealed (surprisingly?) that dogs barking incessantly in the night rated the highest form of noise pollution on a scale ranging from 1 to 7. The survey revealed a large number of sources of noise that we really dislike. Lawn mowers whining on a summer's day, late-night parties in apartment blocks, noisy neighbors, vehicles of all kinds, especially large container trucks thundering through quiet village, planes and helicopters flying overhead, large radios carried round in public places and played at maximum volume. New technology has also made its own contribution to noise. A lot of people object to mobile phones, especially when they are used in public places like restaurants or on public transport. Loud conversations on mobile phones invade our thoughts or interrupt the pleasure of meeting friends for a quiet chat. The noise pollution survey revealed a rather surprising and possibly amusing old fashioned source of noise. It turned out to be snoring! Men were found to be the worst offenders. It was revealed that 20% of men in their mid-thirties snore. This figure rises to a staggering 60% of men in their sixties. Against these figures, it was found that only 5% of women snore regularly, while the rest are constantly woken or kept awake by their trumpeting partners. Whatever the source of noise, one thing is certain: silence, it seems, has become a golden memory.

防盗警报器在白天和黑夜的任何时候都会响起来，它的作用只是骚扰过路行人，而实际上却帮助窃贼入室行窃。在街上，汽车的防盗警报不断对我们吼叫，这是人们极度烦燥的一个原因，最近一个有关噪音的作用的调查（令人吃惊地）指出，夜间连续不断的狗叫声，在一个从1级至7级刻度表上应列为最严重的噪间污染。这个调查揭示了我们所不喜欢的大量的噪间的来源：夏天呜呜作响的割草机，公寓楼里深夜聚会的喧哗声，大声吵闹的邻居，各式各样的车辆，特别是穿越寂静的村庄的集装箱卡车，从头顶飞过的飞机和直升机，被带到公共场所、音量开到最大的大功率收音机。新技术也为噪音作了它的贡献。许多人都反对移动式电话，特别是在如饭店，公共交通车等公共场所使用移动电话。用移动电话大声交谈干扰我们的思路，破坏我们和朋友在一起轻声聊天所得到的乐趣。这个有关噪音的污染调查还揭示了一种出人意外而同时可能会引人意外而同时可能会引人发笑的老式噪音源。它竟然是鼾声。人类是这方面的罪魁祸首。调查指出，20%的35岁左右的男人打鼾；而到60岁这个年龄段，这个数字上升到令人惊愕的60%。与这些数字相比，只有5% 的女性经常打鼾；而其余则经常被与她们同睡、像吹号似地打着呼噜的男人吵醒或弄得睡不着。不管噪声来自何方，有一点是肯定的：看来寂静已变成一种珍贵的回忆。
