摘　　要：研究车内噪声客观参量与主观感受之间的影响关系。根据车辆安装5种排气系统后在8种不同档位不同转速行驶工况下的车内烦恼度主观评价分值以及11项声学客观参量,采用多元统计的聚类分析根据相似程度将客观参量分类,结合因子分析和相关分析分别提取出了在中低转速和中高转速下最能表征烦恼度的客观参量,将主观烦恼度与客观声学参量相关联,最后采用多元线性回归建立了基于声学客观参量的中低转速和中高转速下车内烦恼度预测模型,相关分析显示,其预测结果与主观评价值之间有较高的相关性。因此,基于声学客观参量的车内烦恼度评价是可行的。The relation between objective physical characters and subjective annoyance from vehicle interior noise was studied. 5 different exhaust configurations were installed on a vehicle respectively, interior noise and psychoacoustic indexes at various operating speeds were calculated, also subjective annoyance was evaluated. Firstly, these indexes were classified according to the similarity among them by means of cluster analysis. Secondly, quantities which are the best indication of interior annoyance were selected using factor analysis combined with correlation analysis. Finally, multiple linear regression was introduced to build vehicle interior annoyance evaluation models at mid-low and mid-high speeds, respectively, they were verified using correlation check with subjective evaluation results.
