Virtual Reality (VR) can potentially transport the user to another world. Outside of VR, musical soundtrack is usually placed outside of the scene, referred to as non-diegetic sound. In VR, this could potentially break immersion. Other ways to implement music have to be tested.
A test was created consisting of three scenes with a wide selection of “listening modes”, or musical configurations. The listening modes ranged from non-diegetic stereo music via headphones to diegetic, played from speakers inside the VR spaces. 10 respondents played through the scenes in VR, experiencing every listening mode. Respondents then replied to a questionnaire gathering their thoughts on their experience.
Results showed that immersion improved the more the experience corresponded to expectations from outside of VR. Non-diegetic listening modes were considered less immersive than diegetic listening modes.
This study lays a basic foundation for further research on music in VR with initial guidelines for proper implementation.
