标准范围

指定一种方法,用于测量垂直于测量表面的声强分量,选择该测量表面以封闭要确定声功率级的噪声源。根据测量值计算一倍频程、三分之一倍频程或带限加权声功率级。该方法适用于现场或特殊用途的测试环境,适用于任何可以定义物理固定测量表面的源,并且源产生的噪声在时间上是固定的。

Specifies a method for measuring the component of sound intensity normal to a measurement surface which is chosen so as to enclose the noise source(s) of which the sound power level is to be determined. The one-octave, one-third-octave or band-limited weighted sound power level is calculated from the measured value. The method is applicable in situ or in special purpose test environments to any source for which a physically stationary measurement surface can be defined, and on which the noise generated by the source is stationary in time.
