Michael,

Looking *GOOD*! I love it when the bigger "real" studios post the work in progress. My little one room has a wallboard/wood/wallboard sandwich and I love it. It does a great job of knocking down the sound. I believe the different sound transmission characteristics of the materials really work together well. I also love it because I don't have to find any special place to screw a screw in -- the whole wall is available, not just studs. Makes it easy to hang stuff.

For the sliders - are you using two different thicknesses of glass? Are they angled relative to each other?

Keep posting and letting us know how this progresses! (and watch your back with lifting that stuff! <grin>)

While I'm in warning mode.... fitZ!!! Tie yourself off man. A safety line and a little hassle is well worth it. We need your stories and postings!

Now why didn't I think of that. Thanks for the brain refresher lee. Between the polebarn and the shed, I've been in more dangerous situations than a bordello.:D Actually, I've got the polebarn cross cabled for the winter, and I finished shoring up and rebuilding all the supports on the shed today. The only problem I had is a spider bite last night. I'm ok though. $&^*&&#^%@(& spiders......SQUISH EM ALL!! :p opps, sorry Michael.

Amped - Acoustic treatments; that's a whole other animal in and of itself!
Here's the plan:
Live Room
On the side walls, John has given me permission to build some of his variable bass absorbers. These are a 3 piece unit that utilize Absorbtion, Diffusion, and broad band Absorbtion/Diffusion.
Additionally, the side walls will have furr-downs for electric runs, and A/C return air vents. The front side of these will have random pattern diffusers on them.

The front wall will be alternating panels of cloth covered 703.

The rear wall of the live room, as seen here

lg-312946.jpg

offers significant diffusion due to its angular geometry. Some additional diffusion on the area of the wall above 10' will be implemented using pyrimidal cones or random pattern diffusers.

For the angled ceiling I want to use a pair of parabolic diffusers made from a birch plywood. I saw this type of diffuser used at the studios for NFL Films, and again, I saw them used in a lobby of a large hotel.

The Drum Room
The rear wall of the drum room will use a natural stone wall with the stone set at varying depths for diffusion. The front walls, above the sliders will use cloth covered 703 panels.

The Vocal Booth
I'm still working on a combination of absorbtion/diffusion methods there to bring the RT60 to an acceptable level. Most likely it'll use slot resonators in the corners, and absorptive panels above the window.


The Control Room
The rear wall will have variable slot resonators with bass traps inside. I want to use an RPG type diffuser on the rear wall between the slot resonators, but I'm still weighing the pro's and cons of that.
The front wall will have soffit mounted speakers,set at 30 degrees with a 12 degree down angle, and those soffits are designed in such a way as to provide both absorbtion and bass trapping. Also, there's an angled furrdown at the top of the wall running the length of the front wall. It'll be covered in cloth only, so that its.... open, and have 703 on the inside top and sides that will offer significant bass trapping, and absorption of frequencies in the higher mids.
The side walls, with their sliders in place, offer a highly reflective surface, and some absorbtion above those should prove appropriate.
The rearward sloping ceiling of the CR should require little treatment, but some deep set absorbtion will raise the response enough to tame some mid frequency demons.

Laptopp - The sliders have dual panes and the glass is different thickness. There is 6 degrees of separation between the sliders.

Cool, Michael - as usual, it sounds like you know what you really need and have your ducks already marinated; and you're absolutely right about not worrying more over wall construction - your double sliders, while a really nice vibe, will limit isolation as you mentioned.

Not enough to cause concern though - I've heard just a single heavy slider in a couple of music store booths that had more isolation than I thought possible, so doubles of a similar quality should be best of both worlds.

Everybody else - thanks for your compliments; several of my friends say I shoulda been a teacher - I usually tell 'em I couldn't take the pay cut :=) but I think they're right, I can hardly stand not to share when I learn new stuff... Steve
 
Michael,

Those diffusors loof PFCool. Are you buying or building? Are they backed with anything, like a minicloud?

It seems like you could build them by putting turnbuckles running diagonally across the corners of a rectangle of plywood, tightening to achieve benditude, then backing with some high-density fiberglass.

I'm a bit of a cheapskate and find the prefab acoustic solutions to be outrageously priced. But then, my studio doesn't look half as cool as your joint...
 
I'd like to build them Todd.
I too, find pre-fab acoustic solutions priced too high!

I would think you'd want to back them with some 703 or Knauff or other high density, rigid insulation - that's my plan anyway.

I'm anxious to start acoustic treatments, but other things have to happen first.
Electrical is finally getting roughed in on Wednesday (October 29th); finally, after seeking many bids for that part of construction.

The company I went with actually saved me a bunch of money. I was planning on having a new, underground service brought in, but they added up all the amperage of all my equipment, all the lights, outlets, and everything else, then figured out that I could upgrade my existing service, and come off of that.

They'll have to pull new wire through the existing conduit from the house to the transformer, but that's better (cheaper) than having to install new conduit, pull new wire, set a new meter, and wire the studio. And all of my outlets will have dedicated grounds too.

We finished the final sheetrock for the rear wall last night, and I called in an inspection this morning. After that passes, we can tape and float that wall, then resume the framing on the CR!

After electrical rough-in, I have an HVAC contractor comming in to rough-in the vents for A/C.

It's comming along.

i didn't understand the speaker angle terminology?
12deg down? absorption of the monitors?

curious, are you doing bass traps in the front or just the back?
 
The control room wall is 10' high at the front; 11'-6" at the rear.
The speakers sit at about 62". With out the downward angle, they'd be firing over your head.
This way the cones concentrate the music, in 3 dimensions, at the mix position.

righteous bass trap & panels dude

thats creative engineering on the traps...been scouring thru the pages of acoustic bliss and haven't seen that with the port and all.....rocknroll.
 
I wish I could take credit for it, but that's actually John Sayer's design.
