俺英语水平很差,提供几篇英文,前辈能不能给翻译一下。
第一篇:If you live in a large city, you are quite familiar with some of the problems of noise,but because of some of its harmful effects, you may not be aware of its influence on human behavior. In recent years there has been a great deal of interest in the effects of noise on human behavior, and concepts such as \"noise pollution\"have arisen.
Exposure to loud noises can definitely produce a partial or complete loss of hearing depending on the intensity, duration, and frequency composition of the noses.Many jobs present noise hazards, such as working in factories and around jet aircraft, driving farm tractors, and working (or sitting) in music halls where rock bands are playing.In general, continuous exposure to sounds of over 80 decibels can be considered dangerous. If exposure is for a sufficient period of time, it may produce significant hearing loss.
Noise can have unexpected harmful effects on performance of certain kinds of tasks, for instance, if one is performing a watch keeping task that requires vigilance, in which he is responsible for detecting weak signals of some kind.
Communication with other people is unfavorably affected by noise. If you have ridden in the area of a jet transport, you adjusted the loudness of your speed to compensate for the effect. The problem is noise. |
