Here you can see an example of a diffusion coefficient normalised to a flat surface. The calculations is based on ISO 17497-2 from my personal investigation. I'm looking for reliable datas for any diffuser device to start comparison work.
maybe you can find some on the RPG products site and the GIK products site. i remember seeing plots there -- not sure to what standard or testing labs were used.
