The best expanation I have found in english is:
the perforated panels provide efficient acoustic absorption in the low mid frequency range, while proving a degree of scattering/diffusion at higher frequencies.
The absorption characteristics of the perforated panels vary depending on the distance they are supported away from a solid boundary. The closer to the boundary, the lower the overall absorption at higher frequencies.
The panels can be mounted at an angle to the room boundaries to reduce effects such as "flutter echo".
When arrayed in groups in front of a solid, flat boundary, the diffusion effect of the panels extends to the lower mid frequencies.
I don´t know if they do all this hu-hah quted above but the rooms I have sound great. For having a low ceiling I am really suprised how good my mastering room turned out so the diffusors must be doing what they are supposed to.
