semi anechoic chamber

This paper introduces the matter of 3m semi anechoic chamber and the testing technology and results of emi.

文章介绍了建设3米法半电波暗室应注意的问题以及EMI实际测试技巧和特殊测试结果分析。

The noise of 4110Q diesel engine and its oil pan, flywheel cover, oil pump, valve chamber has been studied by the analysis system of B&K3560 in the normal Semi-anechoic chamber.

在标准半消声室，用B&K3560噪声测量分析系统对4110Q柴油机整机和油底壳、飞轮壳、喷油泵、摇臂罩等零部件的噪声进行了台架试验研究。

To test this scheme, experiment was conducted in a semi-anechoic chamber, with 3 loudspeakers simulating the sound sources of the 3 separate sections of the volume target.

为验证此方案，在半消声室进行了非典型声强向量阵的定向实验，用3个扬声器模拟体积目标3个不同部位的声源。
