Description

Abstract—

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.
