Tiff, welcome back! My famous thumb is just fine, after all, I've got brand new nail. It took three months to grow out. I would like to see your building progress very much ... you know ... I'm voyeur too. I'm pretty sure your work will be just fine, even better than mine. If you make it solid, functional and good sounding – that's the goal we are looking for, at least that's more important than the good looking make up, at least for me (that reminds me on „how to chose a wife“ advice) . Bring the pics here ... we're on fire!
Today – BIG step forward! BIG!!!
My friend Darko with his compressor gun and experience made me smile. We were done with 7 frames in three hours! As I mentioned in my previous post, the front cover is doubled. OK, maybe you think I'm overdoing this but I hate even to think about itchy particles.
That's not the plugin. It's real 1176. What a machine ... impressively fast. It's so easy to work with ... you just walk around, stretch and shoot.
Please, just ignore all the edges. They will be covered with the slats later. I couldn't resist to hanging fever.
Ready? ....
Tomorrow, one more will be hanged on the top of the middle one (wall/ceiling) in „T“ form.
Horizontal member of the „T“ is waiting.
My plan was to finish the cloud (revision C) this week, but I got cold yesterday so that makes me feel and look like ... boiled chicken leg
I almost forgot …. the sound of the room has been drastically changed – to the better. It’s damped but not deaf/anechoic at all. I can still hear some upper ringing/fluttering …. I need the cloud ….
I’m so close …

You are doing such a beautiful job, I just have to ask you a favor...
First, my plan was to use 4 layers of drywall (sheetrock, gypsum board, etc), 2 inside the studio, and 2 outside (room within a room plan), including the ceiling.
My research is such that 3-4 layers is "enough" for "sound proofing," and the beyond that the law of diminishing returns applies...I've completed the inner 2 layers of 5/8" fire code drywall, including the ceiling, and have one layer outside on two (interior) walls, and all 4 on the other two (exterior) walls.
Outside my studio is a hall on one side, and garage on another (so the "air" in both of those spaces will act as one layer of sound proofing for the interior walls), and two walls share the exterior of the house, which already have 2 layers of drywall, plus the stucco exterior wall...
My question is: should I finish the 4th layer of drywall in the hall, and garage???? The hall and garage belong to me. I ask because I want to be finished!
Not trying to thread-jack. Just want your opinion. I will post my "work" in its entirety in a separate thread.
Thanks in advance for your help!!

Not a hi-jack at all. Although I'm not the expert, I could try to help you here (and hope others are watching this thread too, to correct me if I'm wrong).
If I got it right, you've got something like this:
My answer would be - yes. Double layer with its mass should help against airborne noises coming from garage door and the hallway. With each layer of added drywall, in practice, you will improve reduction for 4-5 dB. Of course, it won't help you much against the flanking noises.
The mass is our friend, triple leaf is not. Did you remove the piece of the outside wall to actually see is there something that could create triple leaf wall?

Move the hall in your rendering counter-clock-wise a quarter turn, so it sits left of the studio. Garage is as you have shown (below the studio). The house wraps around the top and left side of the studio.
I'm thinking because the house is to the left of the hall, I don't need the 4th layer of drywall on the wall shared with the studio.
If needed, I can use this hall as a vocal booth, or to isolate an amp... And my original plan called for 4 layers of drywall on the wall separating the hall from the studio.
However, I want to "quit" at three layers of drywall because I'm running out of steam... I have completed all of the drywall except this one layer, and am very anxious to move on to the next phase of construction. I'm simply being lazy, cheap, and hasty!
I want your opinion now, because I must live with my final decision.
Thank for your input! I've enjoyed watching your studio being built. And I look forward to telling my projects story.

Groff,
not quite - it's with each doubling of mass.......
So if you have 2 layers on each face to begin - add 4 more layers (total) to gain 4-5dB (theoretically 6dB) of isolation - then add 8 layers for 4-5dB more - 16 layers for another 4 -5dB, etc., etc., etc.
Sincerely,
Rod

Tiff, could you borrow me a whip, I need double dose.
Adding mass won’t hurt as long it’s not in the triple leaf structure. One (minor) drawback, you will need more bass traps inside the room if the walls are thicker/denser. Three or four layers, it’s hard to tell, depends on how loud you will be or your environment is, and what value of STC or TL you are expecting.
I had similar problem when I was working with my windows. I have one OSB and five drywall layers and I still wish one more, because this is my weakest link.

What is a "triple leaf structure?" Not familiar...
I’m a bit surprised you didn’t hear such important thing in wall construction/soundproofing.
The leaf is a portion of mass (one or more drywall layers). The leaves should be decoupled/separated (without any direct physical contact) with the air gap for the best reduction.
Double leaf means: mass (leaf) – air – mass (leaf). This is how it should be done. Two masses, one cavity.
Triple leaf is: mass – air – mass – air – mass. Three leaves of mass and two cavities. No need to say, this suck.
Type „triple“ in search engine for A&D forum and learn more.
Tiff, seriously, I hope you know you're always welcome into my thread for any reason you've got, I really mean that, and I will always help you as much as I can, but the process of building a studio has so many potential disaster black holes at every stage. Sometimes, just one stupid nail or screw can turn your world up side down. That's the reason why I'm pushing you to start your own thread. If you keep everything for yourself until the end it could be – too late. Here we have guardian angels like Rod, Ethan, Andre ... watching and saving us from our ignorance and mistakes. One reason more, I'm one step to the finish, hardly would anyone check 8th page of this topic about the wall construction. Save your money, time, effort and dream, start the damn thread. What can you lose my friend?
