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，采用等级评分法对车内噪声声品质烦恼度进行主观评价试验，分析计算各噪声样本的心理声学客观参数；通过相关分析和多元线性回归分析，建立匀速车内噪声主观评价烦恼度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声品质烦恼度主要受低沉度和音调度两个心理声学客观参数影响。

Abstract: The interior noise samples from four cars at different positions and different speed were selected as the evaluation objects. The subjective evaluation test of sound quality annoyance was carried out with rating scales method. Several objective psycho-acoustical parameters of these samples were calculated. By way of linear correlation and multi-dimensional regression analysis, an equation between the subjective evaluation of noise annoyance and the objective psycho-acoustical parameters was established. The results indicate that the vehicle interior sound quality annoyance under the good highway and the constant-velocity driving conditions is affected mainly by two psycho-acoustical parameters dichen and tonality.
