Abstract: This paper reviews some research work in the field of industrial noise source location. An analysis technique is presented allowing a representation of acoustic intensity patterns close to radiating surfaces is presented. The technique is based on the measurement of the spatial intensity vector in various points using recent developments in electronic processing equipment and the availability of multi channel Fast Fourier analysers.

Such visualisation techniques lead to a better understanding of some acoustical phenomena, characteristic for the near field such as hydrodynamical short circuits, multipole action, etcÂ… Moreover the technique proves to be a valuable tool for evaluating the accuracy of radiation estimation models. Those models have been developed for predicting the sound radiation pattern of platelike structures as a function of the velocity amplitude distribution of the plates.
