Effects Of Music And Surf Sound On Undergraduates' EEG

The study was to explore that the effects of music and surf sound on undergraduates' electroencephalogram(EEG) and to explore the differences because of gender and personality. Seventy-two Hebei Normal University undergraduates(36 type-A and 36 type-B, 36 male and 36 female) taked part in the experiment. According to matching method, all subjects were divided into three equal groups, music sound, surf sound and sit-rest group. The experiment consisted of three phases. The subjects' EEG were recorded in different phases, with between-group and within-group experimental design. The result showed: Music increased the relative power of θ and α 3, and reduced the relative power of β, the subjects relaxed and quieted more and more; Surf sound increased the relative power of β and α 3, and reduced the relative power of θ , the subjects were awake; There were gender differences, the relative power of α 3 in female was higher than that in male; The trend and extent of EEG change varied in different experiment intervention, listening to music, male relaxed more easily; There was interaction between behavior pattern and experiment intervention, surf sound increased the relative power of α 3 of type-A, and experiment intervention affected type-A more greatly; α 1, α 2 and α 3 indicated different physical and mental state, so, α1,α2 and α 3 should be distinguished in subsequent studies.
