    摘要： This system has a plurality of microphones (3) oriented in several directions and mounted in a support (2) so that each one is flush with or disposed on a rigid surface, the various microphones (3) being connected to a signal processing device that processes the signals coming from the microphones (3) to provide a noise source hologram, namely a distribution of the acoustic pressures or intensities at various points on a given surface.
