Abstract (en)

System and method for detecting location of sound sources in a three-dimensional space using linear microphone arrays comprising a plurality of microphones wherein the microphones are located in at least two groups of at least two microphones wherein each group has a different spacing of the respective microphones. Three such linear microphone arrays are used wherein first ends of all three microphone arrays, comprising the same arrangement of microphones, are in proximity or adjacent to each other; and the separate microphone arrays are positioned in different planes in three-dimensional space.
