Abstract
This paper is made to observe the impact of 3D (three-dimensional) and 2D (two-dimensional) music on autonomic nervous system and to explore the mechanism of the music. This study changes and retains some musical elements of the four music, and 73 healthy participants listened to four music tracks with headphones: 3D slow music, 2D slow music, 3D fast music, and 2D fast music. The results show that galvanic skin response (GSR) data decreased in all participants after listening to 3D music. Among them, the first and third 3D music, which bears obvious characteristics of sound spatial movements, high melody definition, stable rhythm structure, and high timbre identification of the main melody significantly changed participants' GSR compared to the benchmark obtained before the experiment (P<0.05). It can be reasonably argued that 3D music may improve the regulation of autonomic nervous system responses, which contributes to the health of mind and body.
