Would love to hear opinions on this research. I was under the impression that QRD diffusers perform better than hemicylinders (subjectively, in control rooms). I don't completely understand everything about the tests/results in this study, but it looks like the hemicylinder they tested created more diffuse polar patterns in more freq. ranges, and had better "diffusion uniformity coefficients" than the QRD. Thoughts?
Measurement of sound scattering properties of diffusing panels through the Wave Field Synthesis approach

Field measurements show hemicylinder diffusers perform better than QRDs?
