A state-space representation of the boundary integral equation for room acoustic modelling
Randall Ali, Thomas Dietzen, Matteo Scerbo +2
We introduce a new framework for room acoustics modelling based on a state-space model of the boundary integral equation representing the sound field in a room. Whereas state-space…
On Time Delay Interpolation for Improved Acoustic Reflector Localization
Hannes Rosseel, Toon van Waterschoot
The localization of acoustic reflectors is a fundamental component in various applications, including room acoustics analysis, sound source localization, and acoustic scene analysi…
Tracking of Spatially Dynamic Room Impulse Responses Along Locally Linearized Trajectories
Kathleen MacWilliam, Thomas Dietzen, Toon van Waterschoot
Measuring room impulse responses (RIRs) at multiple spatial points is a time-consuming task, while simulations require detailed knowledge of the room's acoustic environment. In pri…
Sound Field Reconstruction Using Physics-Informed Boundary Integral Networks
Stefano Damiano, Toon van Waterschoot
Sound field reconstruction refers to the problem of estimating the acoustic pressure field over an arbitrary region of space, using only a limited set of measurements. Physics-info…
A State-of-the-Art Review on Acoustic Preservation of Historical Worship Spaces through Auralization
Hannes Rosseel, Toon van Waterschoot
Historical Worship Spaces (HWS) are significant architectural landmarks which hold both cultural and spiritual value. The acoustic properties of these spaces play a crucial role in…
A Comparative Analysis of Generalised Echo and Interference Cancelling and Extended Multichannel Wiener Filtering for Combined Noise Reduction and Acoustic Echo Cancellation
Arnout Roebben, Toon van Waterschoot, Marc Moonen
Two algorithms for combined acoustic echo cancellation (AEC) and noise reduction (NR) are analysed, namely the generalised echo and interference canceller (GEIC) and the extended m…
State-Space Estimation of Spatially Dynamic Room Impulse Responses using a Room Acoustic Model-based Prior
Kathleen MacWilliam, Thomas Dietzen, Randall Ali +1
The estimation of room impulse responses (RIRs) between static loudspeaker and microphone locations can be done using a number of well-established measurement and inference procedu…
