Error Estimation and Stopping Criteria for Krylov-Based Model Order Reduction in Acoustics
Siyang Hu, Nick Wulbusch, Alexey Chernov +1
Depending on the frequency range of interest, finite element-based modeling of acoustic problems leads to dynamical systems with very high dimensional state spaces. As these models…

Bayesian parameter identification in impedance boundary conditions for Helmholtz problems
Nick Wulbusch, Reinhild Roden, Matthias Blau +1
We consider the problem of identifying the acoustic impedance of a wall surface from noisy pressure measurements in a closed room using a Bayesian approach. The room acoustics is m…
