So I'm just going to throw out some information, my plans, and a couple of questions, and I would appreciate feedback (i.e. identifying pitfalls I haven't foreseen). Thanks in advance!
ROOM INFO
I have an unfinished room in my basement, 13.5'W x 23'L x 8'H with the following characteristics, positions relative to my mix position:
PLANS
My current idea is to finish framing the entire room, put in electrical, but stay away from the drywall - instead, using insulation, combined with acoustically transparent fabric pinned between studs/joists on the walls and ceiling, for absorption. I don't mind a dry room. This will mostly be for private recording work. Isolation is not a significant concern.
I'd be going for Live-End/Dead-End format, with the whole ceiling as absorptive as I can make it, full absorption in the dead (front) end, and "half" absorption in the walls of the "live end." (Alternating insulation between every other stud.) The floor is concrete, and would be finished with vinyl flooring.
QUESTIONS
THANK YOU!
ROOM INFO
I have an unfinished room in my basement, 13.5'W x 23'L x 8'H with the following characteristics, positions relative to my mix position:
- Home foundation on front (W) and left (L) sides
- Partially finished right (L) wall, 2"x8" studs, with drywall on the outside of studs. Door on right wall, near rear right corner.
- Sheet metal on the right wall in front of aforementioned door, for HVAC return air. Floor to ceiling, about 4.5' wide.
- 2"x4" studs on back (W) wall, and will have a door on back wall, rear left corner.
- 2x12 joists above ceiling.
- There's currently a huge null at 54 (±4) Hz currently, which is pervasive throughout the room. My best guess is the drywall on the outside of the right wall is resonating at that frequency.

QUESTIONS
- I'm far from a building code expert (if you haven't noticed already), so if I try to put in ceiling light fixtures and electrical outlets in cutouts of the fabric, am I going to run into problems?
- What type of insulation will give me the most low-frequency absorption for the buck? I do have to keep this on a relatively modest ($1000-1500 total for insulation) budget. This is also why I'd rather not finish with drywall. It would increase the acoustic treatment costs by a significant factor.
THANK YOU!
