A Study on the Effects of Different Intensity Musical Stimulation on Learners' Attention and Meditation

Having good concentration can help people acquire more knowledge and information in a limited time, therefore, how to use music to enhance the concentration level of online learning to improve learning efficiency has been paid attention to by the majority of educators. Electroencephalogram(EEG) is a comprehensive representation of neuronal activity in the human brain and contains rich physiological neural information. This paper studies the effects of musical stimulation on learners' attention and meditation in online learning environment based on EEG and explores the differences between different types of learners. In this experiment, it’s found that: 1) learners' attention reaches the highest value of 58.3 when the music intensity is 56 dB ± 3 dB, while meditation reaches the best value of 64.8 when the intensity is 56 dB ± 3 dB. 2) the optimal intensity for active learners' attention is 5 dB lower than that of passive learners, but the attention is 8.2 higher than that of passive learners. The mean and maximum of attention for female learners and male learners are approximately the same, but the optimal value of music intensity of attention for male is higher than that of female by 6 dB, indicating that the optimal attention that can be achieved by male and female is not related to gender, but to music intensity. 3) Meanwhile, this paper finds that the meditation of active learners is 4.8 lower than that of passive learners when the music intensity is 56 dB ± 3 dB, which indicates that active learners are more tense and their attention is not easy to keep stable; while on the whole, the meditation of female learners is higher than that of male learners by 4.2 on average, which indicates that women are more relaxed and easier to stay focused in soft music.
