Acoustic treatment

Post by Harper »

Hey everyone,
John did a layout for me, but I need to know where to put my treatment

I've marked out where i think they should go, just want to make sure.

Thanks

I'd do the front wall between speakers absorptive to kill any reflections off the rear of the console/desk.

The rear wall should be just absorptive, unless you have at least 10-12 feet between the back of your head and the rear of the room - otherwise, early reflections smear your stereo imaging by random phase cancellation -

The slots on the front sides are fine, as are the hangars in bass traps at the rear corners.

Hope that helped... Steve

Hey Steve
Thanks for the help

But I was wondering what to do for the front of my rear corner bass
absorbers? In John's wall unit section of the site he has a slat front
is that what I should do?
or is there something else i should do?

Harper - in the section between the speakers I'd do both slots and absorbers. Check out the front of Sonar Studios at the studios under construction site.

For the rear wall you can have the angled slots provided you cover the front with absorption as well.

Back Wall treatment?

Post by dymaxian »

Hey Steve!

You mention above that if the back wall is within 10-12 feet of the back of your head, you ought to absorb as much as you can to keep early reflections down...

Im wondering about the treatment of the rear wall in a much longer room- like 20 to 25 feet long. Again, I'm thinking about making the control room big enough to use as rehearsal spot for my band, instead of making 2 smaller rooms. But in that light, I wouldn't want the back end of the room to be too dead; when we do end up recording in that room, I don't want the room to soak up everything.

Perhaps I can play with the wall shape to keep any direct reflections from coming right back to the listening position, but with a distance that great it seems like I wouldn't have to make it as absorptive as I'd thought...

What do you think?
