A Stand for Measurement and Prediction of Scattering Properties of Diffusers

Document Thumbnail

In this paper we present a set of solutions that may be used for prototyping and simulation of acoustic scattering devices. The system proposed is capable of measuring sound field. Also a way to use an open source solution for simulation of scattering phenomena occurring in proximity of acoustic diffusers is shown. The result of our work are measurement procedure and a prototype of the simulation script based on FEniCS - an open source computing platform for the FEM-based solution of differential equations. A visualization and comparison between data obtained from measurement and an example of the simulation scenario are presented and discussed.
