The progress in some investigion aspects of near–field acoustic holography(NAH), includingreconstruction algorithm, data acquisition and anlysis system,data interpolation & extrapolation on holography plane,no-stationary sound field reconstruction and holography reconstruction error analysis, was reviewed in this paper. The problems that exist in NAH were analized,and the solution to the problems was gave.The focal points of the investigayion in the fu-ture were also point out.
