Time Domain Room Acoustic Solver with a Fourth-Order Explicit FEM Using Modified Time Inte... This paper by Yoshida et al. [[7]] presents a proposal of a time domain room acoustic solver using a novel fourth-order accurate explicit time domain finite element method (TD-FEM). Satisfactory acoustics is crucial for the ability of spaces such as auditoriums and lecture rooms to perform their primary function. To predict the sound absorption coefficient of the MEMM, the capability of three conventional models and three machine learning (ML) models of the supervised learning method were studied for the development of the prediction model. Potential of Room Acoustic Solver with the Plane-Wave Enriched Finite Element Method A preliminary study on the partition of unity finite element method (PUFEM) as a room acoustic solver was presented by Okuzono et al.
