Investigations on real-scale experiments for the measurement of the ISO scattering coefficient in the reverberation room

An ISO working group is preparing a standard for measuring the random-incidence scattering coefficient in the reverberation room [1]. This paper comments on the experiments with the realscale application of this technique to a sine-shaped surface, a one-dimensional and a twodimensional diffuser and discusses on several parameters that are related to the measurement quality and reliability.
