| Abstract: | A built-up circular piston sound source is established in this paper. The directivity formula of its far field is obtained, and its validity is simulated. As a result, the sound source not only can suppress effectively side lobe and reduce the width of main lobe, but also has its directivity at any acoustic frequency. The higher the acoustic frequency is, the stronger its directivity is. |
| Keywords: | built-up circular piston sound source far field simulation directivity |
