摘要

以驾驶员耳处采集的乘用车发动机启动时声样本为对象,分析了其时频域分布,计算了声样本的基本物理参数、心理声学参数和烦恼度指标。运用成对比较法进行了声样本主观评价实验,得出各声样本主观偏好性得分。通过主、客观参数的相关分析和回归分析表明:烦恼度模型能正确预测声样本的主观偏好性,双耳响度和粗糙度是影响主观偏好性评价的主要客观参量,用对数变换后的拟合模型能更好的描述主观评价结果与客观参量之间的关系。

Abstract

The acoustic samples of passenger car when its engine starting taken at the position of the driver’s ear are selected as the object to calculate and analyze its time-frequency distribution, physical parameters and psychoacoustics parameters. Subjective testing is carried out via the paired comparison method. The subjective preference scores of samples are concluded. The results through linear correlation and multi-dimensional regression analysis show that the psychoacoustic annoyance (PA) can predict the preference evaluation correctly, and loudness and roughness strength are the dominant metrics influencing the preference evaluation of interior sound of passenger car when its engine starting, and the equation with logarithmic transformation describes the relationship between subjective preference scores and objective parameters preferably.
