标准范围

指定测量声源周围测量表面上的声压级和计算声源产生的声功率级的方法。给出了测试环境和仪器的要求，以及获得表面声压级的技术，根据该声压级计算声源的A加权声功率级和倍频程或三分之一倍频程带声功率级。该方法可用于进行验收试验。

Specifies methods for measuring the sound pressure levels on a measurement surface enveloping a source, and for calculating the sound power level produced by the source. Gives requirements for the test environment and instrumentation, as well as techniques for obtaining the surface sound pressure level from which the A-weighted sound power level of the source and octave or one-third-octave band sound power levels are calculated. This method may be used to perform acceptance tests.
