Binaural Beat Technology and Rhythmical Photic Stimulation

During intervention, the participants close their eyes and wear an eye mask and stereo earphones. They then listen to 30 minutes of 10 Hz BBT music (intercalated with relaxing music) through their mobile phone. The intervention music was first embedded in the participant's mobile phone and the BBT music application was purchased from the mobile phone app (Brainwave Studio software, Dalcoms Inc). When listening to music, 10 Hz light stimulation was added to the BBT and FL group (using a mobile phone). Table 1 shows the intervention status. The rhythmical photic stimulation program was a commercially available mobile phone app (Strobe Therapy software released by FuwhatSoft).

Participants in the sound therapy group (BBT) listened to 30 minutes of 10 Hz BBT music (intercalated with relaxing music) through their mobile phones. Except for rhythmical photic stimulation, the other steps were the same as the BBT and FL group.

Participants listened to 30 minutes of relaxing music (the same as that of the experimental groups) through their mobile phone. Except for rhythmical photic stimulation and 10 Hz BBT, the other steps were the same as the experimental groups.
