Large Scale FEM Analysis of a Studio Room

In room acoustics, particle models like ray tracing and image source method are not sufficient to explain the wave nature especially at low frequencies. For detailed acoustic investigation, many wave-based approaches like FEM, BEM and finite difference methods have been proposed. We present an application of large scale FEM analysis in order to obtain eigenmodes and transfer functions of a real-world studio with general impedance boundary conditions. The results thus obtained are compared with the measured data and are in fair agreement with each other. Since, FEM needs discretization of domain into small elements like tetrahedral and hexahedral, we also propose a novel all-hexahedral mesh generator for arbitrary shaped rooms and show its application in room acoustics.
