Abstract

The purpose of this study was to compare how three kinds of emotionally different music impacted on the emotion and arousal by measuring EEG. The research method was to compare the measurement of the background EEG on Fp1 and Fp2 before, while and after listening using a 2-channel EEG device with various experimental groups aging from 20s to 50s. The results were as follows. 1) At both Fp1 and Fp2, the amplitude of alpha(8-13Hz), SMR(12-15Hz), low beta, high beta, and ${\alpha}/-{\beta}$significantly increased in all music, while at Fp2 only, theta and ??/SMR increased meaningfully.2) At right prefrontal cortex(Fp2), all bands of EEG predominated while and after listening to all songs over Fp1 except for the delta of funeral march which predominated while listening to Fp1.3) The music with a noticeably high alpha value and increased activity was Prelude. These results suggested that Prelude induced brain activity along with relaxation, and the emotionally heavy burden of funeral march decreased the activity of the left brain. This research revealed that feeling emotional change by listening to music was due to the fact that music influenced the brain activity inducing the change of emotion and arousal.

본 연구의 목적은 느낌이 다른 3가지 감성적인 음악이 감성과 주의각성에 미치는 영향을 뇌파 측정을 통해 비교하고자 하였다. 연구 방법은 20대부터 50대까지 다양한 실험군에게 2채널 뇌파측정기를 이용하여 Fp1과 Fp2에서 청취전 배경뇌파를 측정하고 청취중과 청취후의 뇌파를 측정하여 상호 비교 하였다. 연구 결과는 1)시간이 경과함에 따라 Fp1, Fp2의 알파, SMR, 저베타, 고베타, ${\alpha}/-{\beta}$가 유의하게 증가했고, Fp2의 세타, $_{\theta}/SMR$이 유의하게 증가했다. 2)장송곡의 델타를 제외한 모든 곡들의 청취중 뇌파와 청취후 뇌파는 Fp2가 우세했으나 장송곡은 Fp1의 델타파가 우세했으며, 3)알파값이 눈에 띄게 높아지고 활동성이 증가한 음악은 프랠류드였다. 이는 편안한 느낌의 프랠류드가 뇌의 이완과 더불어 활성을 유도하며, 무거운 느낌의 장송공은 좌뇌의 활동성을 저하 시키는 것으로 판단된다. 이 연구 결과로 음악을 청취하고 감성의 변화를 느끼는 것은 음악이 실제로 뇌의 활동성에 영향을 미쳐 감성적인 변화와 주의 각성의 차이를 유도하기 때문인 것으로 밝혀졌다.
