Wood Diffuser

How effective would these diffusers be in the vocal booth and live room?

They look simple to build and I like the way they look, any thoughts.

Thanks,
Rob

They look great, but they'd make rather poor diffusors. Looks like a cool way to make slot absorbers though. Just imagine building cavities into the walls and mounting those in front!

Ah, so what you're saying is that they would be much more effective if I cut openings in the wall and these were installed in the opening so it was flush with the wall, or on the outside of the opening.

I mainly concerned with how to get diffused sound in my live room - where the drums will be - without buying foam or plastic diffusers.

Thanks,
Rob

Greetings! This isn't too far off from what I'm doing to my ceiling. I'll post pictures soon. There's a link around here somewhere that I got the general idea from, but I can't seem to find it now.

Anyway, I have these wood slats set on end, but they're cut a little different. I took 1x6 lumber, and using a band-saw I cut a sine-wave shape right down the middle. The peaks are 2" from each side, so each board gave me a pair of baffles that range from 2" to 4" deep. I also set the band-saw table at a 30degree angle, so the flat faces of the baffles won't reflect straight back. So each baffle has a continuously-changing angle of reflection. I'm making them 2' long, and mounting them in 2'x2' squares in such way that the angled faces alternate directions and the waves don't line up with each other. They're connected to each other by a 1x4 slat pn each end, so between the baffles is mostly open. I was thinking of mounting them over rigid insulation or another absorber, but my ceiling doesn't have the head-height.

It's pretty cool looking- I think it looks like some Machiavellian portcullis. My wife thinks it looks like bad dental work. Once I get more of them built and hung, I'll get some pics up.

It may not be the best diffusor in the world, but it sure cuts down direct reflections.

See yaz!

I would certainly be intersted in seeing your design. I really don't want to use prefab foam diffusers so I'm looking for alternatives, especially a design I can build using wood so it warms up the studio somewhat...

Thanks!
