| Abstract: | 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. |
