| Abstract: | A complex sound intensity analysis system was developed based on LabVIEW software development platform and the fundamental principle of complex sound intensity measure. The sound intensity measuring and sound field analysis for a minivan were carried out by means of the developed system and the 3D-sound intensity maps, intensity contour plots and frequency maps of the vehicle interior noise radiated surface were identified. The location and identification of noise radiated from this surfaces were performed successfully. |
