| 摘 要： | 以6种B级轿车在不同车速下匀速行驶时的车内噪声样本为评价对象,采用成对比较法对B级轿车的噪声品质偏好性进行了主观评价试验,计算了各噪声样本的主要心理声学客观参数,并通过线性相关分析和多元回归分析,建立了噪声偏好性主观评价的数学模型。研究表明,在匀速工况下B级车的噪声品质偏好性主要受响度和尖锐度两个参数影响。

| Abstract: | The interior noise samples from six types of B-class cars driven at different speeds were selected as the evaluation objects.The subjective evaluation test of sound quality preference was carried out with the paired comparison.Several objective psycho-acoustical parameters of these samples were calculated.By means of linear correlation and multi-dimensional regression analysis,a mathematical model for subjective evaluation of noise preference was established.The results indicate that the B-class car＇s sound quality preference under the constant-velocity driving condition is affected by two parameters： loudness and sharpness. |
