【摘要】 为确定阻抗管内传递矩阵法测量材料传声损失的适用范围,四个声学专业实验室进行了同样材料的对比实验,17种材料,26个样品被调查,得到了有用的结论。除此,一些测试结果还与质量定律进行了对比并改进了样品安置管。
【Abstract】 To determine the appropriate applying range of the transfer matrix measurement method of transmission loss in impedance tubes,four professional acoustical laboratories have made a comparative experiment referring to seventeen classes of material and twenty-six samples and acquired some useful conclusions.Furthermore,the quality law of sound isolation has been particularly introduced into the experiment,and the sample-mounting tube has been improved.
