ABSTRACT:
A system and computer implemented method for determining and displaying vector acoustic intensity fields based on signals from a rigid spherical array of acoustic sensors within a volume external to the array. The method includes a propagator with a ratio of Green's functions for the location within the volume and for the spherical array radius, and a Tikhonov regularization filter that uses the Morozov discrepancy principle on the measured noise variance and Fourier coefficients of the measured partial pressures with respect to reference accelerometer or microphone measurements.
