摘要
在GB/T 3767-2016《声学声压法测定噪声源声功率级和声能量级反射面上方近似自由场的工程法》的基础上,本文研究了两种不同的测量表面(半球形和平行六面体)对声功率级测量结果的影响,分析表明这两种测量表面的选择对测量结果准确性的影响几乎忽略不计,具有较好的一致性,同时对这两种测量表面的工程试验提出应用建议,高效提升产品噪声测量评价。
Based on the sound power level measurement of the noise source by using the sound pressure method in GB/T 3767-2016,this document studies the impact of two different measurement surfaces(hemispherical and parallelepiped)on the measurement results of sound power levels.The analysis shows that the impact of the selection of two measurement surfaces on the accuracy of measurement results is almost ignored,and the impact is good consistency.At the same time,application suggestions are proposed for the engineering test of the two measurement surfaces to efficiently improve the product noise measurement.
