Abstract

The Finite-Difference Time-Domain (FDTD) approximation method has been introduced into acoustics in the last years to solve field problems numerically. However, the huge computer power needed to be used in the modeling of large rooms has delayed the launch of commercial applications, being the major part based on ray-tracing. This paper analyzes the viability of a FDTD implementation for this task in today’s personal computers and presents the resulting application. All simulation stages from the architectural model, the generation of the mesh, implementation of the recursion, parallelization and finally the result in the form of impulse response are discussed.
