Powerfulness, Unpleasantness and booming sensation of car interior noise were investigated using continuous 7 categorical judgment,]According to the results obtained, even under the exposure of the same car interior noise, their judgments varied with respect to the variation of the vibration level. The tradeoff effects expressed in sound pressure level in dB were in proportion to the variation of seat vibration level in case of the evaluation of powerfulness but those tended to show saturation with respect to the variation of seat vibration level in case of the evaluations of unpleasantness and booming sensation. The effect of seat vibration to the perception of sound quality of car interior noise is smallest in case of booming sensation.
