Wall square footage = 222. I used 12 tubes of GG. All boards were cut and fit together with minimum spacing, fastened with 1 5/8 inch screws and taped with paper. As I was mudding today I enjoyed the sounds of neighborhood dogs and people yelling. As I put my head against the wall I could CLEARLY hear the barking dogs. I went into another part of the bedroom, put my head up to the drywall, and boom... same noise. I didn't need to put my head to the wall in the closet, I just did it to find the source of the noise. The noise was clearly coming in. And for the GG diehards, there are NO other places for noise to come into this closet AND I'm not hearing it coming from someplace else. Simple test, put head to the wall with GG and hear noise, put head to wall w/o GG and hear same noise. The noise isn't really even muffled in the closet. Also, I followed the instructions to a T. (Random pattern on board with about a 2 inch border) 2 tubes per 8X4 board.
Maybe this stuff helps reduce home theater noise going out, but it is useless for preventing noise coming in the home. Please don't respond and ask obvious questions. I drywalled correctly and installed GG correctly. I'm positive someone will quote this out and insist on making an assumption about installation or room environment and I'll respond.
I did read this stuff takes 30 days to cure but what is frightening is I really hear no difference. To me, the product works if you can experience it working first hand. I can't imagine this stuff will go from providing minimal reduction to the great product everyone rants and raves over. Come to think of it, I haven't found a single post about someone who has used this stuff in my scenario and had significant results. Maybe this is why I can only post to the theater design section.
My advice, and take this from first hand experience from someone using his ears, don't use this product to eliminate outside noises.
Here's my advice, if you want quiet move into a solid brick home on a few acres out in the country. Don't try and GG some drywall in a house made from 1/2 drywall and exterior vinyl siding.
I shut my door into my newly GG'd closet and listen to loud engines, neighbors ,and barking dogs.
I have an extra case and I want my money back. I busted my butt this weekend with hope and instead all I got is my clothes spread out all over the house.
And for those of you telling me it works great in your home theaters,
A.) I can't validate that by listening with my EARS.
B.) I don't want to get into a comparison of how many drywall layers, tubes, etc.
I can just say, one additional layer installed as mentioned above had a VERY minimal effect.
