本标准提供了一种根据工作站和其他指定位置的所有类型机械和设备产生的声功率级确定发射声压级的方法。这些声压级通常低于机器或设备在正常环境下运行时测量的声压级，而机器或设备 环境可能会影响发射声压级的测量。

This Standard provides a method for determining emission sound pressure levels from the sound power level produced by all types of machinery and equipment at work stations and other specified locations. These sound pressure levels are in general less than those that would be measured when the machinery or equipment is operating in its normal surroundings where the environment may influence the measurement of an emission sound pressure level.
