In theis paper, the characteristics of sound insulation of a typical aicraft sidewall structure have been investigated. 研究了典型飞机壁板结构的隔声特性。
The result is important for solving the problems of the bad repeatability and low measurement accuracy in the structure sound insulation measurements. 对解决结构隔声测试方法中声源信号可重复性差，测试结果精确度不高的问题具有重要意义。
