在工业生产中,由于某些工艺的需要,生产线上使用气动手工具的数量越来越多.这类工具A声级一般均在90dB左右,有的高达100dB以上,呈中高频特性,危害严重.因此,降低气动工具的噪声势在必行.为配合制定气动工具噪声测量方法及噪声限量国家标准,进而有效地控制气动工具噪声,我们对国内现有多种气动工具进行了测试分析,现就气动工具噪声测量中的三个问题作一探讨. In industrial production, due to the needs of certain processes, the number of pneumatic hand tools used in the production line is more and more.The A sound level of such tools are generally about 90dB, and some are as high as above 100dB, with high-frequency characteristics, Therefore, to reduce the noise of pneumatic tools is imperative.In order to cooperate with the development of national standards for noise measurement methods and noise limits of pneumatic tools, and then effectively control the noise of pneumatic tools, we have carried out the test and analysis on the existing pneumatic tools in our country. Three issues in the measurement of pneumatic tools noise are discussed.
