Virtual Building Acoustics

Building Acoustics

Building acoustics is the research area that covers all aspects of sound and vibration in built-up structures. We give emphasis to the acoustical performance of buildings as derived from the performance of the elements comprising various structures. This project covers airborne sound insulation and sound transmission, and the basic aspects of noise and irrelevant speech problems connected to internal and external sound sources.


The basic principle of building acoustic auralization is to simulate the alteration of a sound signal from its source to the receiver via transmission through the building structures. The auralization of a situation requires modelling of sound propagation, where the sound from one space is transmitted through building structures to another neighboring space. On the other hand for an outdoor moving sound source, the modelling of outdoor sound field and its transmission through façade elements of buildings is involved.

Virtual Reality

Audio is crucial for creating a convincing Virtual Reality (VR) experience. Because of the key role that audio cues play in our sense of being present in an actual, physical space, as it contributes to the user’s sense of immersion. This project focuses on the basics of 3D graphics rendering tools that are vital for building acoustics implementation to create virtual built-up environments and audio rendering techniques, real time convolution, filter design and building acoustics auralization plugin that make VR realistic as well as sounds realistic.

Audio-Visual Virtual Reality Environments

Perception, Evaluation, Cognition

Congnitive Performance Listening Experiment Setup

Cognitive Performance: Background Noise

Investigation of perceptual localization capabilities of human under building acoustical conditions during background noise from outdoor moving sound sources. Specifically, the aim of such listening experiment is to validate the real-time building acoustic rendering framework for facade sound insulation based on VBA framework (Virtual Building Acoustics Framework)

Effects of Pass-by Outdoor Sources

Cognitive performance during background noise from neighboring private offices to evaluate how it affect cognitive performance in terms of short-term memory.  The listen experiment is designed to investigate the effect patterns of the different background sounds under different building acoustics conditions for indoor scenes and compare results with that of real-life laboratory listening experiments. With this, it is to validate VBA as an audio-visual virtual reality framework as a potential tool for exploring sound effects of building characteristics for different real life activities.
