摘要
建立了正八边形活塞声源模型,求出了该声源的声压分布函数和指向性函数.利用Matlab对声源的指向性进行了三维和二维仿真,并与正四边形活塞声源指向性对比,得出了正八边形活塞声源辐射远声场的指向性特点.为正八边形活塞声源的应用和其他声源的指向性分析提供了一定的参考.
A positive octagonal piston sound somme model is established, and the sound pressure distribution function and directivity function of the sound source are obtained. The directionality of the sound source is sMulated by Matlab in 3D and 2D, and the positive quadrilateral piston sound source is compared, the directivity of the far-field of the positive octagonal piston source radiation is obtained. It provides a reference for the application of positive octagonal piston sound source and the directivity analysis of other sound sources.
