摘要
基于椭圆形活塞声源的应用需要,依据声场辐射理论,计算了椭圆形活塞声源辐射声场的远场指向性函数。利用MATLAB软件对椭圆形活塞声源的远场指向性进行了模拟和分析,得到了其指向性随声源的几何尺寸、频率和定向面的变化规律,对椭圆形活塞声源的应用,以及其他声源辐射声场的指向性研究有一定的指导意义。
Based on the application of oval piston sound source,according to the theory of sound field radiation,the far-field directivity function of the sound field radiated by an oval piston sound By using MATLAB software,the far field directivity of the oval piston sound source was simulated and analyzed,and the variation of its directivity with the geometrical size,frequency and orientation of the sound source was obtained.lt had some guiding significance for the study of the application of the oval piston sound source and the directivity of radiated sound field of other sound sources.
