摘要
汽车车门声品质是汽车声品质研究的重要内容。首先对所采集的车门关闭声音样本进行主观评价实验,并运用Bradley-Terry模型对声音样本偏好性进行分析。然后通过Head Artemis软件进行时频域分析、滤波分析和计算响度、尖锐度等心理声学参数对声音样本做出客观评价。
Sound quality of vehicle door is an important topic of sound quality research of vehicles. In this paper, the jury evaluation experiments on vehicle＇s door-shut sound are carried out, and the preference of the sound samples is analyzed by using Bradley-Terry model. Then, with Head Artemis software, objective evaluation is performed by time-frequency analysis and filtering analysis, and calculations of psyehoacoustic parameters such as loudness and sharpness.
