The light-music association investigation based on physiological responses and emotional ratings

Abstract

An experiment based on physiological parameters and subjective emotional changes was designed to analyze the association of light and music. The different effects caused by music in major and minor were studied. Three mono-color light conditions (R, G, B) and warm-white in 3000K CCT and cold-white in 6000K CCT were evaluated in the same process. The experimental results showed that changes in the environment lead to physiological and psychological responses. Changes in all light colors and music had significant impacts on heart rate and respiratory rate. Analyzed with the valence-arousal of subjective emotions, it was found that music in major had a more positive influence on mood than music in minor, and white light had a more positive influence on mood than three monochromatic lights. A joint analysis of physiology and psychology found that the emotions stimulated by music in minor were most likely to be associated with blue light under low light level, while the emotions stimulated by music in major were most likely to be associated with the high correlated color temperature white light. The results confirm that light and music will influence both physiological parameters and subjective emotions.
