Preservation and Reproduction of Real Soundscapes in Virtual Space for the "100 Best Soundscapes in Japan"

Abstract

In this study, we developed a soundscape system that reproduces a real soundscape in 3D in a virtual space, based on the "100 Best Soundscapes in Japan" selected by the Ministry of the Environment. Using the game engine "Unity", we proposed a method of embedding recorded sound sources into virtual objects placed in a virtual space, and sequentially playing back the sound when the user walks or turns around in the virtual space. By using this system, it is possible to reproduce the same sound field in the virtual space as in the real space, and it can be applied in various places.
