Experience with measurement of diffusion coefficient in a free field

Original language description

The acoustic behavior of diffusers is usually described by three parameters: sound absorption co-efficient, scattering coefficient and diffusion coefficient. The first two coefficients are measured in a reverberation room and have been standardized for many years. This contribution deals with the measurement of the diffusion coefficient of surfaces in an anechoic room characterizing the directional uniformity of the sound scattering. The diffusion coefficient is defined in ISO 17497-2 issued in 2012. The measurement technique was tested on an MLS diffuser of the 4th order. Measured results were in good conformity with theoretical assumptions.
