In situ Measurement Methods for Characterising Sound Diffusion
Two methods have been investigated to define a new way of measuring diffusion in situ. The first one is based on the measurement of a mono-dimensional reverberation time between two parallel plates and gives an evaluation of a scattering coefficient. This field method has been tested through computer simulation and shows high sensitivity to experimental conditions. The experimental set-up has been realized and laboratory measurements conducted. The second method is focused on the scale of a concert hall and proposes new parameters which could lead to a new global diffusivity index. It has been simulated with a computer model with various diffuser arrangements.
These two methods are complementary and if further developed could lead to efficient tools for evaluating and optimizing diffusion in real concert halls.
