Sound proofing over existing construction - 5/10/2013 5:32:28 AM

My landlord's daughter is coming home for college for at least the summer. (It's not clear if she is going back in the fall.) We are both quiet and considerate normally, but the wall we share is very thin and the noise was problematic when she was home for winter break, even with ear plugs. There's more noise on my side when my man is here as he likes to watch movies and have sex (not at the same time.)

My noise is a problem for her as well.

My landlord lets me do anything I want as long as I pay for it, and I'd like suggestions for what we can put on her wall. (I have chemical sensitivity and there are not many construction materials I can tolerate.) I could put quilts up on my wall but I don't know how effective that would be.

When my mom built a drum room for my brother in her barn basement, she used something called beaver board, which I don't see on homedepot.com, but realize they don't list all of their products online.

Considering the state of A's room, aesthetics are not terribly important to her, but they are somewhat important to my landlord. Something nice looking would be more palatable. He is handy, has tools, and time.

I have all of the second floor except for her room and was not aware my bedroom wall was shared when I agreed to take the place.

Thanks in advance for your suggestions!

Now, if you don't want the expense of doing acoustic foam, hit up your local greasy spoon for all their old egg flats, staple gun to wall, have fun painting. .... we did that in high school as a cheap way to soundproof the band practice room and it ended up wild looking tie dye on the walls.

You could have someone come out and spray cellulose insulation into the wall. Although I'm not entirely sure it can be done without tearing the drywall off first.

Make damn sure you don't create a fire hazard.

They just make a few holes and spray it in. The landlord keeps saying he insulated the wall when he put it up, but I will run this past him.

Ya, that's $200/2x2x12 = $4.16 per sq ft.

If the foam dosn't work and y'all don't come up with anything cheaper, I will pitch http://www.homedepot.com/p/dB-3-4-ft-x-8-ft-Acoustical-Barrier-DB348X96BX/100663624#.UY01mz6ihPd which is supposed to go on the inside but reviewers mentioned using it like wallpaper and is under $1/ sq ft.

Like the first one, get thinner cheaper styrofoam panels, and staple or glue egg cartons to them and go to town. Have him try to park the cadillac in the garage while watching a movie, say Hush, Hush Sweet Charrolett and see if that don't change the big O end of the deal. You gotta know your equipment, know what I mean?

Dense pack cellulose is a fairly good sound barrier and can be easily done from either side of the wall, yours or hers with minimal prep.
The steps require cutting a single 2 inch hole between each stud bay of the wall , then inserting the blower hose into that opening and filling it. Once process is done, seal and tape the whole using drywall mud, sand, prime and paint. Only difficulty may be in what form of insulation is already in place. Regular fiberglass bats are no problem but yellow, sound attenuated batting is much denser and more resistant to compaction. Many insulation contractors will do the cutting of openings and filling of the walls for under a dollar a square foot.

Another option would be building a secondary wall on the existing one using "Z" channel and attaching a new layer of sheet rock, typically 1/2", to that "Z". by doing this, you are creating a dead space between the two surfaces which limits the ability of the sound to transfer by conduction. This builds out the room it is applied to by approximately 1 1/4 inches and can be taped, sanded and painted easily. total cost would be about 10 dollars per 32 square foot. if doing it yourself pay attention to the length of fastener screws as you do not want to come in contact with the original wall as it forms a conductive bybass that will defeat the sound resistance.

Note, doing both, Dense pack from her side, "Z" channel from yours and all but the most arduous noises will be effectively blocked. I say this because the "sounds' you are trying to deal with are probably Voice not the heavy thumping base of a punk rock band and in the higher ranges, dampening works fine for all but the loudest of protests.

Also note, neither of these would be true "soundproofing' rather noise suppression measures. Full sound proofing can require extensive and expensive measures from floating floors and ceilings, non paralleled surfaces, custom surfacing, false walling and channeling and can run into the 100,000 dollar range (think sound recording studios, of which I have designed and built two professionally).

I find it terribly amusing so many people on a bdsm forum know about sound proofing. It's almost like we might tend to make noises we don't want anyone else hearing. :)

if it was my place I would build another wall with a good sized air cavity in between it and the existing wall & extra layers of drywall with green glue in between the layers. I find this site pretty good, you might consider Wall solution 4 or Wall solution 5 (better but costs more).. price them out.. you would need to move electric outlets out more for the increased depth... and I would use something around them too, like acoustical putty or other sound deading alternative products.. lots of info on this site.. I dont really think there is an "easy" solution, they all require a certain amount of effort but you have a man, put him to work (hope he's handy)..
