Estimation of Direction of Arrival of Multiple Sound Sources in 3D Space Using B-Format

Hasan Khaddour, Jiri Schimmel, Michal Trzos


This contribution deals with sound sourcelocalization in the three-dimensional space. An energeticanalysis method based on B-format signals processing ispresented in this paper. This method is able to localize multiplesound sources in the three dimensional space. A singleSoundField microphone can be used to pick-up B-formatsignals indirectly. The method has been simulated in Matlaband tested in a real environment. Experimental resultsdemonstrate the validity of this method.
