Not-Quite Iso Booth Idea

[c7sus]

I'm thinking about building some panels to isolate my mics from the noisy room. I'm thinking panels about 7'6" tall by 24 inches wide, and about 2 inches thick. On the side facing the room I would use a slat resonator and the panel would be filled with rockwool covered in muslin material. On the side facing the mic I would cover the panel with 1/4 inch fiberboard and face that with 2 or 3 inch Aurelex foam. I figure I could use hinges to support the panels, locking them together. Maybe if need be I could rig a top for it, too. I found a Luxo mount that would work great in a booth. You can get multiple bases too so you could mount high or low for guitars, etc.

Is the slot resonator idea viable? It occured to me that just making a panel with fiberboard one both sides and filling it with rockwool was kinda defeating the absorbtive qualities of the rockwool.

The next thing I gotta do is make some kind of box to put this damned CPU in because the sound of those platters is making me crazy!

yeah - you are kinda doubling up with rockwool and foam. You could make a MDF panel with 1" Rockwool on one side and slots on the other. see attachment.

Thanks John. Any recommendations on how wide to make slots and spacing to best defeat hard-drive frequencies? I assume the slotted side faces away from the performer........
