Psychophysiological restoration effects through the experience of Gugak soundscape content

The psychophysiological restoration effects of content combining Korean natural soundscape with Gugak, traditional Korean music, were validated through a VR CAVE environment. Participants experienced the content of their choice while seated in a comfortable capsule-shaped chair over a total period of 6 weeks. Psychological responses, heart rate variability (HRV), and electroencephalogram (EEG) were measured before and after each experience, including 4 weeks after the last (10th week). Acute and chronic effects were confirmed through various correlations derived from the data related to physical parameters that depict the characteristics of the soundscape environment, subjective evaluation results of the soundscape, and physiological response measurements, as well as significant changes in psychophysiological parameters related to restoration.
