| 摘 要： | 文章针对提高目前使用的高声强混响室-2163m3混响室声场的高频性能,对两个EPT-200高频声发生器系统进行分析评估。首先采用开环噪声试验,验证其性能指标是否满足要求;然后采用闭环噪声试验,以考察2163m3混响室声场的高频性能。分析结果表明:EPT-200声发生器性能指标满足要求,并且提高了2163m3混响室的高频性能。

| Abstract: | Two EPT-200 high frequency noise generators are assessed with respect to the enhancement of the capability of the 2163m3 reverberation chamber in the range of high frequency. Their performances are tested in open loop acoustic environments, and the capability of the 2163m3 reverberation chamber is tested in the range of high frequency in close loop acoustic environments. The results show that the performances of the two generators meet the requirements and the capability of the 2163m3 reverberation chamber in the range of high frequency is improved. |
