Localization of Dipole Noise Sources Using Planar Microphone Arrays

摘要

The classical algorithm for localizing noise sources using a planar microphone array is generalized to the case of its application to dipole-type sources. The developed algorithm was verified and validated via data processing of experimental studies of cylinder flow noise and jet-plate interaction noise. We compare the results of localizing dipole noise sources using a planar microphone array employing the developed algorithm and an azimuthal array based on the azimuthal decomposition technique.
