摘　　要：以汽车不同位置点采集到的声音信号为实验样本,运用成对比较法对其进行偏好性的声品质主观评价。进而采用聚类分析法,对偏好性不同的人群进行分类,使用频谱技术并结合声压级、粗糙度、尖锐度等声品质客观参数分析了两类人主观评价结果异同的原因。In this paper, the sound samples are acquired from different positions of a stationary car. The subjective preference evaluation of sound quality is carried out with the paired comparison method. People with different preference are divided into two classes by hierarchical cluster method. The objective sound quality parameters, such as pressure level, sharpness and roughness are used to explain the cause of similarities and differences between the two kinds of people with the frequency spectrum technique.
