Abstract: The interior noise samples from four cars at different positions and different speeds were selected as the evaluation objects. The subjective evaluation test of sound quality preference was carried out with paired comparison method. Several objective psycho-acoustical parameters of these samples were calculated and analyzed. On the basis of accurate calculation of misjudgment rate of the evaluation results, a numerical model between the subjective evaluation results of noise samples and the objective psycho-acoustical parameters was established by correlation and linear regression analysis, in the case of constant speed. The research results indicate that the vehicle interior sound quality preference on the good highway and with the constant velocity is affected mainly by two psycho-acoustical parameters, that is, loudness and sharpness.

摘要： 以4种类型轿车在不同车速下匀速行驶时不同位置点采集到的车内噪声样本为评价对象，采用成对比较法对车内噪声品质偏好性进行了主观评价试验，分析 计算了各噪声样本的心理声学客观参数；在精确计算评价结果误判率的基础上，通过相关分析和线性回归分析，建立了匀速工况下车内噪声主观评价结果与心理 声学客观参数间的数学模型。研究结果表明：在良好路面和匀速工况下车内噪声品质主要受响度和尖锐度两个心理声学客观参数影响。
