New mix room- Acoustics help
Posted: Tue Jun 30, 2020 1:35 pm
First post- Hopefully I got everything right and won't be banned forever.
Just moved into a new mix room and need some help tuning it up.
Here's some basics:
- Room is 26'6" x16'6" with a 9'x9' extension in the rear left.
- Existing space, room is 2nd floor over hallway and between two 2-story warehouses (fun)
- Left wall is brick/concrete block, front wall is brick, all other walls are insulated metal stud with 5/8" sheetrock
- Floor (front half) is 2 layers of 3/8" sheetrock sandwiched between 3/4" plywood. 2x8 joist with sheetrock ceiling below. Area under desk/rug is ~9'x12' 8mm rubber flooring
- Floor (back half of room) is 5/8" diamond plate steel covered by 8mm rubber flooring
- Ceiling is concrete, 11’ high with two 9'x6'x3’extensions (removed skylights), 2x8 joist and plywood to roof. These extensions are 14’ high inside.
- All beams and columns are concrete.
- Double doors are (semi) permanently closed, covered by 10’ curtain, room is accessed by 30' door only.
Existing treatment:
Right Wall:
10- 2'x4'x2" panels
Left Wall:
12- 2'x4'x2" panels
12'x20"x18" roxul stuffed soffit (floor/wall corner)
Front wall corners:
2'x8' floor to ceiling roxul stuffed corners
Rear Wall:
4- 2'x4'x2" panels
Rear Left Corner 8'x4" corner trap
Rear Right:
8'x4" corner trap
10' curtains
Floor:
2- 5'x7' shag rugs
1- 8'x11' Shag rug
1- 8'x11' Area Rug
Ceiling:
Untreated except for 8'x6' cloud over mix position, 7'6" from floor at 5 degrees
I've added all relevant drawings, photos, REW data in my Dropbox
I probably have whatever information you need, and am just forgetting to post it here.
Notes: I'd like whatever I do to be able to be moved when I leave this space, as I won't be here forever and I don't own the building.
Ideally I won't drill into the ceiling anymore than I already have. Also need to work around sprinklers
Isolation? Doesn't matter. I can make as much noise as I want, and don't have to worry about much noise from outside the room. Hint: I'm not all that loud anyway.
Here's my current goal- Knock down the resonance at ~48Hz and ~68Hz. Whatever other improvements can be made are also appreciated. I'm considering GIK's scopus tuned bass traps, as (most of) the open spaces between panels are hot at 50Hz and 70Hz, but I'd like to hear about other (better?) options. Budget- $5k?
EDIT: Should I add some diffusion?
What would you do?
Thank you!
