【摘要】 以蓝、粉、灰、橙、红5种颜色的汽车内饰图片作为视觉刺激,以5种汽车典型运行工况下采集到的车内噪声样本作为评价对象,构成25组视听组合。首先,利用语义细分法对待测声音样本的10种听觉属性进行主观评价。然后以"豪华感"和"运动感"作为声品质整体主观评价指标,利用基于熵权的逼近理想解排序(Technique for order preference by similarity to i-deal solution,TOPSIS)方法对主观评价结果进行综合评价。试验结果表明:在蓝色图片刺激下声音样本"豪华感"最强,橙色最弱;在红色图片刺激下"运动感"最强,粉色最弱。因此,可以通过视听交互作用来实现车内噪声品质的改善。更多还原

【Abstract】 Five pictures of auto-inner ornament with different colors are taken and presented on a liquid crystal screen as visual stimuli.Five in-vehicle noise samples are acquired from five types of car under different conditions as evaluation objects."Luxury" and "Sporty" are taken as the subjective indexes.First,semantic differential experiments are conducted to evaluate ten hearing characteristics of 25 groups of audio-visual combination.Then the subjective evaluation results of sound quality are comprehensively evaluated using the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) based on entropy weight.The results show a tendency to consider "blue" as the strongest "luxury" color and "orange" as the weakest "luxury" color;"red" as the strongest "sporty" color and "pink" as the weakest "sporty" color.Statistic results show that colors as the visual stimuli can improve the sound quality of vehicle-interior.更多还原
