11811 音楽がドライバの緊張度及び運転操作に与える影響に関する研究(OS5 運動と制御(2),オーガナイズドセッション)

抄録

The effect of music on driver's mental stress and driver's operation was researched with a simulator. Subjects were 3 healthy males. The heartbeat was measured for about 5 minutes without any stimulation, then for about three minutes simulated while listening to music with driving simulator, and finally, for a few times until observer was settling down. LF/HF and Reactive value, and Standard deviation of horizontal displacement, and Standard deviation of vehicle speed is used for the analysis (LF and HF denote the low frequency component and the high frequency component of the power spectra of heartbeat fluctuations, respectively). Under the speed of 60km/h music influence on driving is not so large. The influence is larger when vehicle speed becomes faster. It may be understood that subjects were similarly influenced by music when standard deviation of the fluctuation of vehicle speed is paid attention. As a result, a high relation between speed control and steering wheel control was read from the graph. It is revealed that the best music on driver's mental stress is usual tempo music.
