The different synesthesia effects with soundless dynamic lighting and musical dynamic lighting

Dynamic lighting has been proved to have substantial physical, psychological and sociological effects on humans. The degree of the response depends on the intensity, the light color, the flickering frequency and the duration of lighting. The study examined the physiological response to soundless lighting and musical dynamic lighting. Therefore, the physiological signals were recorded to investigate the resonance between the exposure of no sound dynamic lighting with different color (red, green, blue, 3000K, 6000K) and musical dynamic lighting. In the experiment, the heart rate, respiratory rate and electrodermal activity are recorded under dynamic lighting conditions. The results show that the musical dynamic lighting environment has a stronger impact on emotional perception than no sound dynamic lighting. Music plays a main effect role in the sound-light fusion environment. The physiological response is most sensitive under the fusion of dynamic lighting and music. This research will help us better understand synesthesia and provide theoretical support for the future practical application in meta-universe and such virtual simulation area.
