| Abstract: | In this paper,a study on planar near-field acoustical holography scan measurement method and how window function and K-space filter affect holography reconstruction is presented.Firstly,holography scan measurement on the acoustic source in three parallel planes is taken,then the acoustic pressure of the other two planes is holography reconstructed using the measured acoustic pressure of the middle plane,and finally the reconstructed and the measured results are compared,which shows that the acoustical holog... |
