| Abstract: | The sound field distribution of a broadband array is calculated using the acoustics FEM and BEM.The FEM-BEM model is established for a nine-element plane array and its numerical method of calculating mutual radiation impedance among the transducers is given. The changing law of mutual radiation impedance influencing acoustics performances is analyzed. The directivity and beam width of the plane array are calculated at three resonance frequencies.A broadband dense plane array with nine elements is developed ... |
