top view. perhaps if the spaces were smaller in between. the smaller the spaces, the higher the frequency, correct?
Hello foreverain. If you are going to that much trouble, why not adhere to principles that are based on known geometrys/sequences/periods, and have been tested, such as Quadradic Residue, Prime Root or even fractal types. Actually, even your design is based on Schroeder type diffusers, with wells and dividers. However, the difference is these are designed with mathimatical formuli that predict precise well depths, widths and periods etc. It would behoove you to read up on this subject, as I believe you could easily waste a lot of time and material on something that just doesn't work. , Even though common sense may tell you that sound reflects off any surface, that doesn't mean that it will result in a diffuse sound field. For instance, what very few articles mention, is you could actually make the soundfield WORSE, as these type of diffusers are 1/4 wavelength SILENCERS as well
I suggest going here and read up a little. Just to illustrate the scienctific background, try reading this thread.

I've personally asked the pros at that site MANY MANY questions regarding these type of diffusers, and there seems to be different schools of thought, disagreement, and plain old dispute sometimes.
Here is a page of "diffuser"
threads. Sometimes, I think this whole subject is SUBJECTIVE

This is why. Here is the best reply I ever heard regarding diffusion. It was by Angelo Campenella..here is what he said..
Heres a little bit of my home-spun philosphy on "diffusion":
1- Diffusion, among other things, depends on the variability if acoustic
impedace across a surface.
2- An absorber placed on a hard surface changes it to be a place where
sound is absorbed instead of reflected.
3- Ergo, places where patches of sound absoption are placed provide a
location where the sound impedance has changed and therefore can act as
a defacto diffusing element of size equal to its dimensions.
4- Therefore, one need not always build awkward objects of wood, plastic
or metal to affect some diffusion: As long as I need or can tolerate a
fair degree of absorption in the subject room, I can place absorber
patches at a variety of locations, and of variable size, and get a very
good start at diffusion.
However, you may want to read something else I have. However, its too long to post here. Let me know if you want to read it, as it is a discussion between two very well known acousticians on this very subject. Let me know and I'll email it to you. PM me if you want it.
BTW, I thought you had some very large polys in your studio? Whats the problem?
