摘要
基于Visual C++和Matlab的联合编程,开发车辆噪声声品质的评价系统.此系统能够对车辆噪声信号进行采集、实时分析和心理声学评价,分析内容包括声音信号的时频分析、A-D计权网络分析、心理声学分析等.对大众AJR发动机噪声信号的采集和分析结果表明,该系统准确可靠,可为车辆噪声评价和声学设计提供依据.
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 evaluation and acoustical design.
