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 ...

Image method for efficiently simulating small‐room acoustics
, 1976 Image methods are commonly used for the analysis of the acoustic properties of enclosures. In this paper we discuss the theoretical and practical use of image techniques for simulating, on a digital computer, the impulse response between two points in a ...
