标准摘要
[中文适用范围]： 指定一种确定与环境声压级评估相关的大型多源工业厂房声功率级的工程方法。 该方法仅限于具有多个噪声源的大型工厂，这些噪声源的主要尺寸位于水平面内，并且其在所有水平方向上基本上均匀地辐射声音。 未加权声压级以倍频程测量。 获得的结果以倍频程表示，如果需要，也可以以 A 计权声功率级表示。 [外文原描述]： Specifies an engineering method for determining the sound power levels of large multisource industrial plants relevant to the evaluation of sound pressure levels in the environment. The method is limited to large industrial plants with multiple noise sources having their main dimensions in the horizontal plane, and which radiate sound substantially uniformly in all horizontal directions. Unweighted sound pressure levels are measured in octave bands. The results obtained are expressed both in octave-band and, if required, in A-weighted sound power levels.
