Will this diffuser design work?

[africantigercow]

Hi there,

I am currently helping a friend treat his new studio to be.

When I suggested that he cover a window with a diffuser. He said he knew of a design for one. Unfortunately I don't know of the name so I cannot search for it. I searched for different types of diffusers and couldn't find anything like it....

I have attached a mock up that he did... we plan on building it with flat square blocks of wood and we are going to get the angle by placing a small block of wood under a different corner...

My brain tells me that it is a design that would work as well as any diffuser... It is perfectly random and there is no point of focus... My mind tells me that the steeper the angle on the pieces of wood, the greater the range of frequencies affected....

Is this a well known design?

Most importantly... will it work?

sorry if this is a bit newb of me...

Thanks for any help...

But you might have to lift the corner 10 or 15 cm (4 to 6 inch) to get much diffusion. Then it will look strange. It's hard to beat a poly-diffuser for results, cost or effort. Never mind what the companies say about their special expensive diffusers.

to answer your question : yes that design will work...But...

Only at very high frequency, given the height of each block. Most diffuser of this type are based on quadratic residue, prime sequence ect. Not random arbitrary placement. You may search the net there is a lot of "how to" available with the right formula and application.

Hope this help.

Hi,

I'M looking to build a diffusor at the moment. From research it's my understanding that your blocks of wood need to be much longer and shorter etc ... to affect frequencies down to 160hz you need at least twelve inches difference in length. As mentioned above, your diffusor would work but only high frequencies. I'M thinking of cutting lengths from 1 inch, 2 inch, 3 inch etc up to twelve inch.

Would anyone disagree with that?

It's not just the depth of the wells that matters: it is the pattern that you arrange them in. Sure, random arrangement will do something, but using a QRD sequence is much more effective.
