摘要
作者讨论了复声强的物理意义。利用7T17S计算机建立的复声强测试系统,对X6130柴油机噪声源识别和控制的试验结果表明:复声强是一种有效的声强分析和声源识别方法。
In this paper the authors describe the physical meaning of compl x acoustic intensity, set up a set of complex acoustic intensity measuring system based on 7T17S computer. The results of noise control and identification test conducted on X6130 diesel engine shows that complex acoustic intensity is a effective means in acoust'c field analysis and acoustic sources Identification.
