不同响度音乐对单调声音环境下驾驶疲劳缓解实验研究

Experiment of Music with Different Loudness Against Driving Fatigue in Monotonous Sound Environment

为有效减轻驾驶员在单调声音环境下的驾驶疲劳、减少交通事故,在不同类型广播声音环境下开展了模拟驾驶实验;基于瞳孔直径变异系数等建立了驾驶疲劳综合评价指标,研究了驾驶疲劳音乐响度对策的有效性。结果表明:音乐能缓解单调声音环境下的驾驶疲劳,在不同声音环境下,音乐对驾驶疲劳缓解的效果略有差异;75和85d B音乐在显著性及稳定性方面要优于65d B;75和85d B音乐两者之间差异不大。

In order to effectively mitigate driving fatigue in monotonous sound environment and reduce traffic accidents,driving simulation experiment was made in different kinds of radio broadcasts environment. Based on the pupil diameter variation coefficients and other indexes,overall evaluation index of driving fatigue was established. The effectiveness of different volume of music as countermeasures against driving fatigue was studied. The result shows that music can be a countermeasure against driving fatigue in monotonous sound environment. In different sound environment,the effectiveness of music against driving fatigue is different. The significance and stability of 75 d B and 85 d B music are better than those of 65 d B,and there are few differences between 75 d B and 85 d B music.
