摘　　要：依据音乐旋律以及节拍对脑电波能量谱的影响,提出一种轻音乐加音乐节拍的双重刺激诱导方法。对测试者的大脑意识活动进行调节,通过分析采集到的脑电信号判断其是否能够快速进入高度放松状态。在调节阶段采用轻音乐加速度渐变和强弱顺序相反的音乐节拍声方式,使被测试者倾听5 min,并对通过EEG耳机采集的脑电信号进行分析。实验结果表明,该方法在调节持续时间约为2 min^3 min时,能够有效地促进大脑进入高度放松状态。The effccts of music melody and beat on Electroencephalogram（ EEG） wave energy spectrum hasve great application significance. This paper proposes a double simulation inducing method with light music and music beats in the hearing. It regulates the brain activity of subjects,and by analyzing the collected EEG signal to determine whether can quickly and effectively enter the highly relaxed state. In the regulating stage, subjects are asked to listen the mix of light music and music beat with the gradual speed and the opposite power order for 5 min, and analyses the signals collected by the EEG headset. Experimental results show that when the duration of regulation is about 2 min ~ 3 min,the method based on double stimulation of light music and music beats can effectively promote subjects to enter the highly relaxed state.
