【摘要】 本文针对强声驱散装置的声学测试进行分析。结合强声驱散装置的使用环境,对半消声室环境下强声驱散器的声学性能进行了仿真及实验分析。首先通过对驱散装置的结构和原理进行分析,对其辐射声场进行估计;然后对强声驱散器发射的声场进行仿真分析,并且将发射调频信号结果与实验结果进行了对比验证,最后对强声驱散器的测试提出了建议。更多还原

【Abstract】 This paper analyzes the acoustic test of a high intensity sound dissipating device.Combined with the use environment of the high intensity sound dissipating device,the acoustic performance of the strong acoustic disperser in the semi-anechoic chamber environment was simulated and analyzed.Firstly,the structure and principle of the dispersing device are analyzed,and the radiated sound field is estimated.Then the sound field emitted by the high intensity sound disperser is simulated and analyzed,and the results of the transmitted FM signal are compared with the experimental results.Finally,Some suggest gived the high intensity sound is the test of the disperser made.更多还原
