Changes in subjective feelings of the male and female participants during the experimental period. (A–D) Changes in the subjective feelings of the male group (n = 8) in each session. (E–H) Changes in the subjective feelings of the female participants (n = 12) in each session. Black and red closed circles are shown for the silent and music sessions, respectively. Data are represented as mean ± SEM and analyzed using a two-way ANOVA. ^***p < 0.01, ^**p < 0.05, and ^*p < 0.1: significantly different between the silent session and the music session at the same time. ^†††p < 0.01, ^††p < 0.05, and ^†p < 0.1: trend significantly different than at the zero point at the beginning of the music session. Data in the silent session did not show any significant differences.
