Comparison of subjective evaluations in virtual and real environments for soundscape researcha).

Emerging technologies of virtual reality (VR) and augmented reality (AR) are enhancing soundscape research, potentially producing new insights by enabling controlled conditions while preserving the context of a virtual gestalt within the soundscape concept. This study explored the ecological validity of virtual environments for subjective evaluations in soundscape research, focusing on the authenticity of virtual audio-visual environments for reproducibility. Different technologies for creating and reproducing virtual environments were compared, including field recording, simulated VR, AR, and audio-only presentation, in two audio-visual reproduction settings, a head-mounted display with head-tracked headphones and a VR lab with head-locked headphones.
