000014806 520__ $$2eng$$aTime-domain near-field acoustical holography is a method used to visualize non-stationary sound radiation. It is based on the use of a microphone array and fast-Fourier transform based convolution. However, current methods are subject to spectral leakage and wrap-around errors. A new formulation based on the time and spatial representation of the transfer function is presented in this paper. The errors are suppressed when this formulation is used in conjunction with linear convolution. It is also shown that the method can be used to monitor impact noises obtained experimentally. Such visualization is an asset in passive noise control for the correction of harmful impact noises often found in industrial environments.
