标准范围

规定了一种工程方法，用于确定与环境中声压级评估相关的大型多源工业厂房的声功率级。该方法仅限于具有多个噪声源的大型工业厂房，这些噪声源的主要尺寸在水平面上，并且在所有水平方向上基本均匀地辐射声音。未加权的声压级以倍频程测量。获得的结果以倍频程和（如果需要）A加权声功率级表示。

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.
