一噪声是人们不需要的干扰声。工业生产过程中产生的噪声称为工业噪声。其大小强弱用声级表示,单位是分贝(dB)。随着工业的发展和城市的建设,噪声的污染面也不断扩大。交通运输造成的噪声虽然波及面广,但从局部来看,工业生产和建筑施工产生之噪声要大的多,对人体的危害也显著的多。在工业生产中,冲压车间产生之噪声比较强大,应该认真对待,积极防治。噪声对于人身的影响和有害作用,可以从
A noise is a noise that people do not need. The noise produced in industrial processes is called industrial noise. The size of the sound level, said strength, the unit is decibel (dB). With the development of industry and the construction of cities, noise pollution is also constantly expanding. Although the noise caused by transportation spreads widely, from a local perspective, the noise produced by industrial production and construction is much larger and harms human beings much more. In industrial production, the noise generated by the stamping shop is relatively strong and should be taken seriously and actively prevented and dealt with. The impact of noise on the human body and the harmful effects can be from
