| 摘 要： | 介绍了跨声速风洞试验段低噪声壁板模型的声学试验。实验结果表明：（1）斜孔所产生的边缘音是最主要的声源；（2）用加网和加隔片都是抑制边缘音的有效方法；（3）文献1]介绍的低噪声壁板的方法具有实用性。

| Abstract: | Acoustical Experiment of Low noise Wall models for testing section in transonic Wind tunnels is introduced in this paper. The Experimental results are provided to show that: (1) edgetone generated by slanted hole configuration is main sound source, (2) Screen and spllitter plates successfully suppress the edgetone, (3) The design way in reference 1] for low noise wall is very useful. |
