【摘要】：利用MP150多道生理仪记录心电信号的变化,从听觉的角度,通过HR(Heart Rate,HR)和频域指标的变化,分析两种节拍的音乐(慢节拍音乐60~100拍/min和快节拍音乐120~160拍/min)对作业疲劳的影响,并以静息组为对照组进行了3组试验。结果表明:1)方差分析表明,音乐对心率变化无较大的影响,而对LF(LowFrequency)、HF(High-Frequency)影响较大;2)心电数据分析表明,短时间聆听慢节拍的音乐有助于心率的恢复;3)心率变异性分析表明,音乐使LF降低,HF升高,副交感神经兴奋性增强,能缓解作业疲劳。
[Abstract]:The changes of electrocardiogram (ECG) were recorded by MP150 multichannel physiological instrument. From the angle of hearing, the changes of HR(Heart RateHRand frequency-domain indexes were studied. The effects of two rhythms (60 / 100 / min of slow beat and 120 / min / min of fast) on work fatigue were analyzed. The rest group was used as the control group. The results showed that the music had no significant effect on the heart rate, but not on the LFV LowFrequency.The analysis of variance showed that music had no significant effect on the heart rate change. HFHV High-Frequency has a great influence; 2) ECG data analysis showed that listening to slow beat music in a short time was helpful to heart rate recovery. 3) Heart rate variability (HRV) analysis showed that LF decreased HF and parasympathetic excitability, which alleviated working fatigue.
