A new method for measuring the scattering coefficient and the diffusion coefficient of panels

摘要

The sound scattering properties of diffusing panels are actually very difficult to measure and to predict. In this paper the Wave Field Synthesis approach is employed for the experimental measurement of the scattering coefficient. The results are in good agreement with the numerical simulations made possible by some recent improvements to the pyramid Tracing algorithm, which takes into account separately the scattering of sound from the edges of finite-size surfaces, and the surface scattering coefficient.
