Surface impedance inference via neural fields and sparse acoustic data obtained by a compact array
Yuanxin Xia, Xinyan Li, Matteo Calafà +2
Standardized laboratory characterizations for absorbing materials rely on idealized sound field assumptions, which deviate largely from real-life conditions. Consequently, \emph{in…

Evaluation of acoustic Green's function in rectangular rooms with general surface impedance walls
Matteo Calafà, Yuanxin Xia, Jonas Brunskog +1
Acoustic room modes admit closed-form expressions for rectangular rooms with perfectly reflecting walls, from which the Green's function can be computed directly through the eigenf…
