Abstract

In this paper, we consider the problem of acoustic source localization using distributed microphone arrays. Time differences of arrival (TDOAs) are estimated using a recently proposed method based on joint direction of arrival (DOA) and range estimation. The TDOAs are used to estimate the location of an acoustic source using a recently proposed method, based on a 4D parameter space defined by the 3D location of the source, and the TDOA. The performance of the proposed method for acoustic source localization is compared to generalized cross-correlation with phase transform (GCC-PHAT), and a method based on joint DOA and pitch estimation, using synthesized harmonic signals with varying source position. Results show a decrease in the error of the estimated position when joint DOA and range estimation is used for TDOA estimation, compared to the GCC-PHAT and joint DOA and pitch methods.
