What is the state of the art technique for the numerical simulation of the propagation of a sound wave inside a room (room acoustics) regarding the time domain? I am specifically interested in the resulting sound field across the room.
Most likely this will be a Finite-Difference Time-Domain (FDTD) scheme. But i am unsure what is considered standard when it comes to simulation accuracy with things like advanced gridding techniques (adaptive mesh-refinement, boundary condition formulations) and modifications of the FDTD scheme (numerical dispersion, stability conditions, discretization schemes).
Hints to relevant papers are appreciated.
