Abstract

Soundscape research stresses the interaction between human beings and sound environments. Virtual reality (VR) technologies provide a vivid approach to boost the virtual sound environment experience for people. However, the real-time VR audio simulation cannot process the complex acoustic conditions (e.g., boundary conditions) due to the high computational cost up to now. This study therefore aims to investigate the applicability of less reflection orders for reproduced sounds in virtual sound environment. To test the effect of reflection orders perceived by people, a series of subject evaluations was carried out based on audio-visual VR experience with different scale public squares reproduced in Unity to provide visual scenarios for the participants. The participants heard typical sounds (e.g., birdsong, clapping and fountain) in these squares, and gave their perception evaluation to these sounds. The results show that these reproduced sounds and typical building spaces can employ less reflection orders which render similar realism and immersion for participants in virtual sound environment.
