摘要
Holographic reconstruction is an inversion method with which the sound radiation characteristics of the sound source can be reconstructed by using nearfield acoustic holography. In this paper, the sound field holographic reconstruction method is researched based on the sound field reconstruction model of nearfield acoustic holography. Using MATLAB and LabVIEW virtual instrument software platform, an integrated sound field holographic reconstruction system is designed and implemented. The functions include sensor array calibration, acoustic signal acquisition and processing, sound field reconstruction, and results visualization. The performance of the presented system was tested by experiments in an anechoic chamber by using a sound box to simulate the sound sources. The experimental results show that the sound field holographic reconstruction system has high location accuracy. Moreover, the effectiveness and practicability of the sound field holographic reconstruction method is verified.
