Gong meditation, also known as gong bath or gong wash, is a form of sound healing where a symphonic gong is played with a mallet to produce overtone-rich vibrations. Participants at public gong meditation events report experiencing deep relaxation among other things. We hypothesize that individuals will show measurable changes in EEG and HRV after 14 days of listening to an 11-minute recording of a gong meditation.
