The filtering window is used during the sound field reconstruction by the method of acoustical holography.To improve the performance of the traditional filtering window,the iterative filtering window between the space domain and the wave-number domain is designed,and the effect of the filtering window is verified by using a synthetic sound field created by apoint-drive and simply supported plate.The result shows that the sound pressure error on the edge of the reconstruction surface is slight and the effect of the designed filtering window is better than any traditional filtering window.
