车内噪声品质偏好性主客观评价及相关性分析

摘要

Parotic noise at back row seat of five types of cars in typical running conditions was collected as evaluation subject. The preference subjective evaluation test of interior noise sound quality preference was carried out by adaptive grouping paired comparison method. The main psychological acoustics parameters of all the samples are calculated, and through correlation analysis and linear multiple regression, a mathematical model which uses loudness and sharpness to describe interior noise quality preference is established. Inversion construction is made to the evaluation results of each group with associated samples, the total sample evaluation results agree well with traditional paired comparison evaluation result, and 50% of evaluation time is saved.%以5种轿车典型运行工况下后排乘员耳旁噪声样本为评价对象,利用自适应分组成对比较法对车内噪声品质进行了偏好性主观评价试验.计算了各样本的主要心理声学参数,通过相关分析和线性多元回归分析,建立了以响度和尖锐度描述车内噪声品质偏好性结果的数学模型.通过各组间的关联样本将各组评价结果进行反演构建,得到的总体样本评价结果与传统成对比较法评价结果一致性好,且节省了50％的评价时间.
