The Influence of Binaural Room Impulse Responses on Externalization in Virtual Reality Scenarios

A headphone-based virtual sound image can not be perceived as perfectly externalized if the acoustic of the synthesized room does not match that of the real listening environment. This effect has been well explored and is known as the room divergence effect (RDE). The RDE is important for perceived...

The RDE is important for perceived externalization of virtual sounds if listeners are aware of the room-related auditory information provided by the listening environment.
