ABSTRACT:
A method of acoustic localization of persons in a detection space by using sound-emitting elements and sound pick-up elements by emitting acoustic signals into the detection space and measuring the reflected acoustic signals has the steps: measurement of acoustic signals in the frequency range of human speech using a plurality of sound pick-up elements; determination of the skew between the acoustic signals measured at the sound pick-up elements; calculation of the position of the sound source from the skew and the positions of the sound pick-up elements.
