摘　　要：以4种不同型号的某国产轿车为研究对象,采集匀速运行工况的副驾驶位置处的噪声样本,对其进行声品质主观评价研究,汽车车内声质量的偏好性随着速度的增加其降低。利用SPSS对其偏好性和客观参量进行线性相关分析,得出车内声品质的好坏与响度和A计权声压级联系紧密,存在强的负相关性,其pearson相关系数分别为-0.991和-0.987。通过计算得出线性回归模型,回归标准化残差的累计概率图显示其模型是正确的。In this paper, four different kinds models of certain domestic cars were chosen as research ob- ject. Noise samples were collected on the co-pilot position at uniform operation velocity, and subjective e- valuation was conducted of sound quality. Car＇ s interior noise preferences lower as speed increases. SPSS was used to analyze the linear correlation between subjective evaluation and objective parameters. The sound quality has close links to loudness and A sound pressure level. The Pearson correlation coefficient was 0. 991 and 0.987, respectively. Drawing the linear regression model, and by returning to the cumula- tive probability of standardized residuals, probability diagram shows the model is correct.
