本国际标准规定了现场测定工作站和附近其他指定位置机械或设备发射声压级的方法。工作站由操作员占用，可位于开放空间、被测源运行的房间、固定在被测源上的驾驶室或远离被测源的外壳内。一个或多个指定位置可能位于工作站附近，或有人值守或无人值守机器附近。这种姿势有时被称为旁观者姿势。 包含以下内容:BS EN ISO 11202:2010

This International Standard specifies a method for determining the emission sound pressure levels of machinery or equipment, at a work station and at other specified positions nearby, in situ. A work station is occupied by an operator and may be located in open space, in the room where the source under test operates, in a cab fixed to the source under test, or in an enclosure remote from the source under test. One or more specified positions may be located in the vicinity of a work station, or in the vicinity of an attended or unattended machine. Such positions are sometimes referred to as bystander positions.Incorporates the following:BS EN ISO 11202:2010
