摘要
文章利用半波长干涉的简单原理制作成高频∞字形指向性传声器 ,同时应用信号处理技术 ,形成简易的早期侧向反射声测试系统 ,在缩尺模型试验中实现早期侧向反射声系数的测量 。
This paper introduces a measuring method of lateral energy fraction in the scale model experiments.According to the interference principle of half wave length making the high frequency figure 8 directional microphone,which,together with the signal processing technique,form a receiving and analysing system,and then the measurements of lateral energy fraction in the scale model are realized.
