音 樂 對 腦 波 及 心 率 變 異 性 的 影 響
2004
The use of music for relaxing and relieving anxiety has become increasing popular in recent years; a lot of relevant research has shown that music has both a mental and physiological effect which is quantifiable. However, some research makes use of EEG to verify the influence that music has on human brain activity. This research measures the brain wave and heart rate variability (HRV) change during the course of experiments in listening to music. Furthermore, I have attempted to distinguish the relation between the music、EEG and HRV. The following points have been discovered: We find that has the biggest alpha power under the situation not listening to the music (baseline), and then listening to relieved the music (soft) is in order, after that alpha power is minimum while listening to the rock music. In gamma band, we find no matter which kind of music is listened to, gamma powers are greater than not to listen to the music .This point and research of the past are duplicated . The influence on gamma band of the music is quite apparent. Whatever the experimenters listen to the music , their gamma band powers are rising. According to relevant research, stimulus to the perception and selective attention caused individual’s gamma power to rise. My experiment also verifies such a statement. Moreover, the music probably makes the change on experimenter''s mood to cause gamma power to rise. We also find that there are greater alpha power on the people who like rock music than people who don’t like when listening to rock music. Finally, positive and negative correlations were found between alpha power and heart rate variability. It was concluded that the result of EEG and HRV are identically.
