音乐节奏对单调高速公路驾驶安全的影响

Music Rhythm Effect on the Safety of Monotonous Driving on Highway

为研究高速公路环境下音乐节奏对驾驶员驾驶状态的影响,选取6位驾驶员参加4组实际道路驾驶试验,4组试验所对应的音乐环境分别为:无音乐、慢节奏、中节奏、快节奏,当被试驾驶至80 min时开始播放相应音乐,并监测驾驶员脑电参数。基于脑电功率谱的比值(α+θ)/β和脑电波SMR波的幅值,分析其变化来研究音乐对驾驶安全的影响。结果表明:在单调高速公路驾驶中,当驾驶员行驶到被动疲劳极限时间80 min后,音乐节奏对驾驶员疲劳状态和注意力水平有显著的影响。

In order to study the influence of music rhythm on the safety of monotonous driving on highway, 6 drivers were selected to receive 4 groups of actual road driving tests. The corresponding music environments to the 4 group tests in the said experiment contained 4 situations as no-music, slow rhythmic music, moderate rhythmic music, fast rhythmic music. After driving for 8 minutes, the experimenter started playing music and meanwhile recording the driver＇ s EEG signals. Based on the ratio of EEG power spectrum （α ＋ θ）/β and SMR wave amplitude, its changes were analyzed to research, the influence of music on driving safety. The results show that the musical rhythm exert a significant effect on the driver fatigue state and the attention level when the driver is driving monotonously for 80 minutes up to the passive fatigue time limit on highway.
