本文介绍飞机强度研究所小型高声强行波管的声学设计和消声降噪处理经使用和测量表明试验段性能良好，可满足声疲劳试验要求，消声道出口噪声达到环境标准．
This paper introduces the acoustic design and anechoic noise reduction of the small high-sound-intensity anastomotic tube at the Aircraft Strength Institute. It shows that the performance of the test section is good and meets the requirements of the acoustic fatigue test. The noise at the noise-canceling outlet meets the environmental standards.
