High potential of small-room acoustic modeling with 3D time-domain finite element method
Frontiers in Built Environment, 2022 Applicability of wave-based acoustics simulation methods in the time domain has increased markedly for performing room-acoustics simulation. They can incorporate sound absorber effects appropriately with a local-reaction frequency-dependent impedance ...
