ISO 6396:2008规定了一种确定土方机械在操作员位置处的发射声压级的方法，该方法根据机器在动态试验条件下运行时的时间平均a加权发射声压级进行测量。 适用于ISO 6165中定义的土方机械和ISO 6395:2008附录A中规定的土方机械。

ISO 6396:2008 specifies a method for determining the emission sound pressure level of earth-moving machinery at the operator's position, measured in terms of the time-averaged A-weighted emission sound pressure level while the machine is operating under dynamic test conditions. It is applicable to earth-moving machinery as defined in ISO 6165 and as specified in ISO 6395:2008, Annex A.
