The changed of power, degree of freedom (df), t and p-values, and size effects (Cohen’s d) are presented. The p-values below 0.05 are highlighted in italics. SHAM = sham condition, BB = binaural beat, AT = autonomous sensory meridian response trigger, CS = combined stimuli of BB and AT at the ratio of 30:60 dB; power = mean ± standard deviation.
