Effects Of Different Types Of Music On Brain Fatigue Recovery Of Grassland Highway Drivers

With the rapid development of economy,the travel demand of grassland residents is increasing,and the traffic demand of grassland highway is also increasing.Due to the unique landscape and unreasonable alignment of grassland highway,drivers are more prone to fatigue when driving on grassland highway.If the brain fatigue caused by driving on grassland highway can not be alleviated in time,it will directly affect the driving safety of drivers.Music can effectively alleviate the driver’s brain fatigue phenomenon in the process of driving,which is conducive to the driver’s driving safety.In order to alleviate the brain fatigue phenomenon of grassland highway drivers,this thesis designed a grassland highway driving simulation experiment,and collected the EEG data of drivers before and after playing different types of music,and analyzed the recovery of different types of music on the driver’s brain fatigue phenomenon,The results of this study provide theoretical support for enriching the phenomenon of brain fatigue during driving on grassland highway:(1)Pop music can relieve the brain fatigue phenomenon of prairie highway drivers.The average power value ofαwave andβwave of 15 drivers were 7.146m V~2/Hz and8.790m V~2/Hz,respectively.Bothαwave andβwave were improved after the stimulation of pop music compared with before the music.The average power ofθwave decreased to10.562m V~2/Hz after stimulation.Pop music,which lasted about 75 seconds,had the worst recovery of all music genres.(2)Folk music can effectively alleviate the brain fatigue phenomenon of grassland highway drivers.After folk music stimulation,the average power value ofαwave is7.264 m V~2/Hz,and the average power value ofβwave is 9.338 m V~2/Hz.After folk music stimulation,αwave andβwave increase greatly.The average power value ofθwave decreased greatly,which was 10.179 m V~2/Hz after stimulation.The stimulation duration of folk music was about 105 seconds,and the recovery effect was better than that of pop music.(3)Rock music has the best alleviating effect on the brain fatigue of drivers on grassland highway,and the changes of each EEG index of drivers before and after music playing are the most obvious.After rock music stimulation,the average power value ofαwave was 7.319 m V~2/Hz,and the average power value ofβwave was 9.868 m V~2/Hz,which increased the most.The average power value ofθwave is 9.593 m V~2/Hz,and the decrease degree is the largest.The duration of the driver being stimulated by the rock music is about 150 seconds,and the recovery effect of driving fatigue is the best.
