A so-called "watch-dog" is built in so that the control processor can not get out of step due to noise interference . 在控制处理器内装有一个监视器，所以它不会因噪音干扰而失去同步。
We shall return to this subject in chapter 13, where the noise properties of some specific systems are described . 在本书第13章中将回到这个题目，在这一章里将要讨论某些具体系统的噪音性质。
But neither psychiatric interviews nor objective tests were able to show any effects upon these american sailors . 但是无论是精神病学的走访或客观的试验，都不能显示噪音对这些美国水兵有任何影响。
A properly designed areal pattern should yield adequate attenuation regardless of the direction in which the noise approaches . 面积组合设计得合适，不论噪音的传播方向如何，都能产生充分的压制效果。
Further reductions in noise might, however, require expensive engine redesign or wholesale changes in road structures, locations etc . 要进一步降低噪音就需付出昂贵代价重新设计发动机或者需要整个地改变道路的结构、区位等。
Areal patterns may be rectangular or along concentric circles, depending on the nature of the noise and on the space available for the array . 面积组合可以是矩形的，或者沿着同心圆周布置，这取决于噪音的性质以及允许的组合间距。
