| Abstract: | Based on hybird programmig of the Visual C++ and Matlab softwares,a sound quality evaluation(SQE) system for vehicle noise was developed.The system can be used for sound signal acquisition,real-time evaluation for vehicle noises,including time-frequency analysis,A-,B-,C-and D-weighting analysis,psychoacoustical analysis and etc..The evaluation results of noise acquisition for Volkswagen type AJR suggest that the newly developed system is accurate and reliable,which can provide a reference for vehicle noise ... |
