The error of complex sound pressure measured on acoustic holograph plane due to error of acoustical holograph measurement system, amplitude error and phase mismatch between different measuring channels, was analyzed, and an approximate error correction expression of holographic reconstruction was deducted. A correction method based on measuring system transfer function was proposed to correct the holographic data, by means of this method, a concise reconstruction’s error expression could be obtained and there was a simple real proportion’s relation between the true value of sound field reconstruction, estimate of sound field reconstruction and error of reconstruction. The effectiveness of educed error expression and error correction method were proved through numerical simulation.
