Towards virtual acoustic reality in the design workflow

Funded by Theatre Projects, a world-class consultancy specialising in the design of performing arts venues, we are delighted to present our latest research at the International Auditorium Acoustics Conference in Bristol held on 8th - 10th September:

“Acoustic Simulation: Odeon vs Treble vs Game Engines.”

This marks an exciting first step towards integrating virtual reality and immersive acoustic simulation into the architectural design process.

Communicating how a space will sound before it is built has always been one of the greatest challenges in architectural design. Sound perception is complex—research consistently shows that it depends on far more than decibels, reverberation times, or other measurable acoustic parameters. Our visual context plays a powerful role. The same sound can be perceived differently depending on its surroundings—just as a room painted in warm colours can feel physically warmer. This understanding highlights the growing importance of multi-sensory simulation in design practice.

Over the past year, we have been exploring how immersive acoustic simulation can be integrated into design workflows at an accessible cost, both in terms of time and required technology.

In our study, we compared established acoustic software Odeon with newer professional platforms Treble, as well as sound simulation systems within the game engine Unreal. The findings were revealing.

Professional acoustic tools remain essential for precise modelling of loudness, reverberation, clarity, and compliance. They offer objective accuracy and control but are typically limited to static sound sources and fixed listening positions. In contrast, game engine-based tools, while less precise, provide interactive and dynamic sound experiences. They support VR devices, allowing both the listener and sound source to move freely through virtual space.

Our research suggests that a hybrid approach—combining the precision of professional acoustic tools with the interactivity of game engines—offers the best of both worlds. This method allows architects and clients to hear and feel how design decisions influence perception, reducing post-construction surprises and bringing design intent to life in a powerful new way.

Ultimately, immersive acoustic simulation helps designers move towards projects conceived and refined with greater confidence, enhancing the emotional connection between people and place.

To discuss how immersive acoustic design could enhance your next project, we’d be delighted to hear from you.
