In this paper the robustness of a previously introduced localization algorithm for multiple acoustic sources is investigated and compared to two popular single-source localization algorithms. To show the versatility of the proposed method, experiments are conducted in various environments with different reverberation times and background noises. In addition, moving speakers are used to show the tracking capability. The application to binaural hearing aids shows the applicability of the algorithm to realistic adverse environments such as, e.g., a cafeteria.
