Visualization of sound fields is useful for accurately understanding and analyzing sound propagation in order to solve acoustic problems. In recent years, mixed reality (MR) devices have advanced significantly, enabling the development of various methods for visualizing acoustic parameters—such as acoustic intensity and sound pressure distribution—in real space. Sound field visualization is not limited to measured acoustic data; numerical simulations can also be used to visualize large-scale sound fields. In particular, visualizing simulation results based on actual room geometry is considered effective for understanding acoustic behavior in realistic environments. In this study, we propose an interactive visualization system for acoustic simulation results that incorporates real-world room geometry using MR devices. The system recognizes the room geometry via the MR device, calculates the sound field using geometric acoustics, and visualizes it directly in physical space. Furthermore, users can interactively modify acoustical conditions, such as the source position, and the corresponding simulated sound field and its visualization are updated immediately Work partially supported by Ono Charitable Trust for Acoustics.
