Acoustic Virtual Reality for Architectual Design

Hermes Sampedro Llopis


Room acoustics simulations are typically divided into two categories - geometrical acoustics methods and wave-based methods. In geometrical acoustics several simplifying approximations regarding sound propagation are made to enable the computational task manageable. On the other hand, in the wave-based methods the governing partial differential equations (PDE's) are solved numerically which are considerably more accurate but computationally more demanding. This project seeks to merge virtual reality with wave-based simulations to provide a more accurate and immersive experience.


The project aims to research novel wave-based virtual acoustics methods suitable for real-time virtual reality (VR) for holistic evaluations of building designs, which will significantly improve the workflow and communication between acousticians and stakeholders, so acoustics can be continuously evaluated throughout the building projects. Reduced basis methods is the key idea that enable the VR system to be real-time, interactive, and physically and perceptually correct.


Use of reduced basis methods to achieve real-time acoustic virtual reality simulations to be applied on the holistic evaluations of building designs.
