标准声源声功率级的半消声室检测法

Method for Semi-anechoic Room Used for Measurement of Sound Power Level of Reference Sound Sources

本文介绍了半消声法检测标准声源声功率级的方法,并对用半消声室法检测标准声源声功率级的测量结果进行了不确定度的评定分析。

This paper introduces a method for reverberation rooms used for measurement of sound power levels of reference sound sources. The uncertainty of results in measurement of sound power level of reference sound sources in the semi-anechoic room is evaluated and analyzed.
