Abstract
In system theory, linear and time-invariant signal processing systems can be described in terms of their poles and residues. These parameters characterize the system’s modes of resonance: poles characterize modal frequency and decay rate, while residues characterize the initial amplitude and phase. Linear time-invariant systems may also be described in state-space form, which characterizes how the system’s current state is affected by the system’s inputs, how it affects the system’s outputs, and how it evolves over time.
This talk will discuss how these principles of system theory may be applied in the context of room acoustics. Several approaches model room acoustics using linear time-invariant systems, mimicking the propagation of sound between sound sources and listeners. In such approaches, system parameters are directly related to physical aspects of the modelled space, e.g. sound pressure levels at different points in space. With this knowledge, analysing the system’s modes of resonance and state-space behaviour can provide information on the acoustic behaviour of the modelled room.
Biography
Matteo Scerbo received his Bachelor’s degree in computer engineering at Università di Genova (UniGe) in 2017. He then specialized in acoustics and signal processing, receiving his Master’s degree in music and acoustics engineering at Politecnico di Milano (PoliMi) in 2021. Since 2021, he has been a PhD student in audio engineering at the University of Surrey (UoS), investigating efficient methods for room acoustics modelling. His interests include room acoustics modelling, digital signal processing, and interactive/immersive audio.
