  • Method of determining noise sound contributions of noise sources of a motorized vehicle
    Patent number: 10288474
    Abstract: The present invention relates to a method and an acoustic measurement system for determining individual noise sound contributions of a plurality of physical noise sources of a motorized vehicle at a target or reference location. The method comprises steps of placing a plurality of reference microphones at respective reference positions adjacent to respective ones of the physical noise sources, placing a measurement microphone at the target location, recording a plurality of noise sound signals and recording a target noise signal. The plurality of noise sound signals are adaptively separated using blind source separation to produce a plurality of mutually independent noise sound signals representing respective estimated noise sound signals of the plurality of physical noise sources.
