摘要
运用分组成对比较法对车内噪声样本进行偏好性主观评价实验,并在精确计算评价结果误判率的基础上,对评价结果进行相关分析和多元回归分析,得到回归方程。最后采用频域滤波技术,识别出指定频率段对车内噪声偏好性的影响。
A subjective rating experiment of sound quality preference on in-car noise samples is performed using group paired comparison method. Based on the precise calculation on misjudgment rate, the correlation analysis and multi-dimensional regression analysis are performed with a regression equation obtained. Finally, frequency filtering technique is adopted and combined with the regression equation to reveal the effect of the designated frequency range on in-car noise preference.
