1. A method for acoustic noise source detection comprising:
disposing an acoustic logging tool into a wellbore;
performing an acoustic logging operation in the wellbore with the acoustic logging tool;
forming an acoustic data set from the acoustic logging operation;
performing a cross-correlation function between pairs of hydrophones using the acoustic data set;
constructing a cost function using at least in part the cross-correlation function to find a noise source distribution; and
identifying a location of the acoustic noise source by inverting the noise source distribution.
