何谓噪声?从广义来讲,凡能引起人们烦恼的声音都是噪声。在工农业生产中,由于机器运转、气体排放、工作撞击等可产生强烈的噪声,称之为生产性噪声。如我厂能产生噪声的工种有:铆接、锻锤、空压机、钣金、试飞等。一般可归纳为以下三种类型: 1.空气动力性噪声 是由于气体压力变化引起气体扰动,气体与其他物体的相互作用新致。例如各种风机、铆枪、空气压缩机和气体排放所发出的噪声。 What is noise? Broadly speaking, everything that causes annoyance to people is noise. In industrial and agricultural production, due to the operation of machinery, gas emissions, work impact can produce strong noise, called the production of noise. If my factory can produce noise, such as: riveting, forging hammer, air compressor, sheet metal, flight test and so on. Generally can be summarized into the following three types: 1. Aerodynamic noise is due to gas pressure changes caused by gas disturbance, gas and other new interactions caused by the object. Such as the noise emitted by various fans, riveters, air compressors and gas emissions.
