Sound proof a wall (by elliot [RI]) Posted on: Jun 13, 2019 8:47 PM

I know this has been discussed before.. I don't remember the verdict.. Is it ever possible to sound proof the wall with adjacent unit?

I moved into one unit of a 9 unit building.. While working on my laptop one week day morning, my immediate neighbor was having a good time at 11:30AM. It almost traumatized me.. Last time I was a renter was more than 20 years ago and people don't make loud noises in that part of the world.

The building was converted from a monastery building 30-40 years ago. The construction was probably typical 2x4. I intend to keep this cash cow for as long as I can..

I don't know if it is feasible, I would like to sound proof it so that I don't hear banging or ...... --108.34.xxx.xx

There is soundproofing that looks like an egg crate and it is made out of foam. Try a music store for a lead on where to get it. You could tack it on and then cover that with a wall to wall drape or just look at the egg crate. My new tenant plays drums so I am going to be looking for it just in case. --173.61.xxx.xx

Here's what we've done in several duplexes with a shared wall between them.

We simply erected a false wall in each room that butted up against adjoining unit. We built the parallel wall with 2x4s, and placed it about 2" from the original wall. We extended any electrical outlets from the original wall to the new wall. We installed Safe&Sound rock wool between the studs of the new wall. Then drywall and paint.

We lost about 6" of room length, but are very satisfied with the results.

You can have the walls foamed. They will drill a hole into each study bay and spray in foam. That will significantly reduce the noise but the only way to make it completely sound proof is to build an offset wall as Glenn mentioned above. You can save some space by abutting sleepers horizontally to the existing wall and covering with sheet rock to get nearly the same effect as a completely off-set wall. --50.26.xx.xxx

Dead space is your friend. The sound Carries through solid materials, especially wood studs. This is why Glen's method works. It creates a deaf soace where there are no solid materials for the sound waves to travel through. --70.178.x.xx

When we built our house, we used a sound-deadening sheet rock called Quiet Rock. It does seem to dampen the sound, but it also interferes with our wifi network. If it still exists, it's worth looking into. --73.231.xxx.xxx

Even when I sound proof walls between units with soundproof special drywall, sounds go through the wooden flooring, baseboards, electrical boxes, frames and other areas. TO do the job right, takes more than 1 step and 1 way of doing it. --47.156.xx.xx

elliot, sound proofing an existing space can get extremely costly real fast. First you need to determine what type of noise are you trying to reduce / eliminate. Once you figure out the type of noise you need to decide how much space & money you are willing to devote to solving the problem.

Google soundproofing music studios for some good info on building new spaces as well as retro fitting existing spaces.

Basically you need to add mass, use materials with different densities, isolate anything (framing, wiring, pipes, flooring, duct work, etc) that provides a way for the sound to travel from 1 space to another space. --96.237.xx.xx

Fiberglass is much more effective than foam which fills the cavities insuring both sides work like a drum head. --76.188.xxx.xx

Along the lines of GlennH's tip, dead air and space between vibrating studs is the best way. However, to save room, you could just rip out the drywall on your side of that wall, add new studs so that they extend 1" into your room over the top plate and bottom plate. Then, place drywall on your studs. This will only cost you 1" of space. The only thing in your wall that touches the existing wall will be the top and bottom plate. This shouldn't be a big deal since you're probably going to get ceiling / floor sound anyway, but it should cut the volume significantly. This is better than any filler you could add in the wall. Dead air is the best sound dampener. --108.69.xxx.xxx

Being small apartments here, I like Landlord ofthe Flies' idea.. It's easy enough to cut sections of the wall and add studs in and dry wall..

For my own future reference, probably build with 2x3,2 parallel walls to achieve the better sound proof when building side by side..

In the same theory, to sound proof upstairs/downstairs, Frame 2nd layer of ceiling (provided existing ceiling is high enough, ie. 8') probably is the easy/cheap way to go.

Thanks! --108.34.xxx.xx

Elliot, if you decide to remove 1 side of the wall's SR & add studs that extend 1" into your space, I would try this;

1. use rigid foam to extent upper & lower plates an inch to match the new stud face, this will help reduce the sound transmission at top & bottom of the wall

2. use 2x3's instead of 2x4's, this will allow you to better weave insulation between the old & new framing

3. block any holes in the existing electrical boxes with tape then use low expansion foam to seal around the boxes, pipes & any penetrations in the wall cavity

4. install drywall high hat channels horizontally across new studs, this greatly reduces areas for sound to be transmitted

5. use 5/8 SR or BB applied vertically to high hat

6. use either caulking or low expansion spray foam to seal around the perimeter of the new SR / BB --96.237.xx.xx

Btw- some Home Depots stock 2 x 3s, some donít. I had been ripping 2x4s, until I figured that out. ( of course, youíve been doing this long enough, you probably know that...) --70.92.xxx.xxx

They make metal spacers that you can attach to existing wall studss, then drywall over the spacers.

Total loss of space would be about 1-1/2". --99.59.x.xxx
