摘要
采集同一品牌两辆不同型号的汽车在不同发动机工况、不同路面状况和不同车内环境情况下的驾驶员右耳处的噪声样本,作为实验评价对象。利用等级评分法进行车内噪声品质的主观评价实验,并对样本进行客观心理声学参数计算。通过对比客观参数之间的关系,找出各工况下对于车内噪声响度、尖锐度的影响。通过相关性分析,建立车内噪声品质主客观评价间的多元线性回归模型。结果表明,在不同的发动机工况、车内环境和路况下,车内声品质主要受响度和尖锐度的影响。
The evaluation subjects are noise samples ,which are taken from the driver＇s right ear position and signals are acquired from different types of engines, driving conditions and vehicle interior environments are acquired from two different-size vehicles of the same brand. The grade scoring method was used as a subjective evaluation method for sound qual- ity ,then psycho-acoustical parameter was calculated by using those samples. By analyzing both objective and subjective outcomes the correlation was found within them. Finally, a multiple linear regression model about vehicle interior noise evaluation was established, by means of correlation analysis. The results show that with different types of engines, road conditions and vehicle interior environments, vehicle interior sound quality can be affected by loudness and sharpness.
