noise from above
« on: March 20, 2012, 04:36:45 AM »
I am having a problem with noise coming from the floor above mine. I can hear the people's footsteps and occasionally I can hear the people talking out loud.  The place is 60 years old and each floor  is made of:

1. oak wood floor
2. subfloor made of 1X4" wood
3. 3" X 12" wood beams. no insulation.
4. metal lathing and plaster ceiling.

This is a problem that I have to fix. I was looking to see if anyone can tell me the best way to deal with the problem? I cannot do anything with the floor above. I have to solve the problem through the ceiling. The ceilings are 8' 8" high so I have room to lower the ceiling. On the other hand I would also be willing to tear down the ceiling if the final product was worth the extra work.

Thanks for the help.

This will be a major project..lathe and plaster are the worst for transmitting impact not to mention back in those days they built houses with real hard wood!!!

The ceiling will need to be torn down and a new soundproof decoupled ceiling put in, but the walls are going to a HUGE player in the end results... normal drywall walls have a lower resonance and therefore the "Flanking noise" isn't that huge of an issue.. with lathe and plaster this is a whole different animal...
would you consider doing one entire room? walls and ceiling?

I don't think that i can do anything to the walls. It would be a huge amount of work. I would have to go down to the brick and start from scratch.  The exterior walls are probably only about 2 or 2.5 inches deep. The way the walls where made was with a 1 X 4 nailed to the brick of the exterior then another 1X4 was nailed perpendicular to the first piece. The metal lathing and plaster is right on top of that. The interior walls have 2x4 so there is some room to work with there. I was thinking that maybe I could cut the top of the plaster about a 6 inches to a foot down and do something there to help with soundproofing. i don't think there is anything i can do with the exterior walls since there isn't much room to work with.


I read somewhere that I could use a closed cell spray foam insulation to help with the noise that comes from them walking. I know that the foam insulation isn't actually a sound barrier itself but because it fits tightly in between the beams that it helps make the floor to vibrate less and therefore helps with the noise. Do you know if  there any truth to that?

No truth to the expansion foam..that is not the primary path of impact...

You can do just the ceiling...just as long as we are the same page in regards to the results...you will still hear a certain value of the impact from the side walls....how much we could not guess.

I understand. I'll do the best i can for now. Maybe down the line I can go back and do the walls as well.

From what I've read it looks as if i would have to demo the existing ceiling. Then I need to install insulation in between the beams. After that I will staple a layer of MLV to the ceiling. On top of that i will install SSP Clips with the SSP RC-2 Pre-Dampened (Resilient Channel w/Iso Tape). Then two layers of Sheetrock separated with a layer of green glue.

Is it worth the money to install quietrock of a similar product instead of sheetrock?

correct.  very good!
note:  clips and standard hat channel not RC-2 pre dampened.

Better to do a layer of 1/4" foam mat on the back of the first layer of drywall instead of quiet rock. Especially for impact noise issues.

after looking at your website i got these part numbers for the material i will need.

09-00005-48-2F - MLV
09-IS - drywall mounting clips
09-RCT - regular hat channel
09-42720-PSA - 1/4" foam mat
09--GREENT -- green glue for in between the sheetrock... i would have to buy the case instead.
09-42745-S -  sealant for joining the sheetrock
09-99913-16 -- insulation

the only thing i would still have to buy is the sheetrock, compound and tape.

you will also need the seam tape for mass loaded vinyl.

I would also consider using the R19x16" insulation for ceiling.

Here is my e-mail address, send me an e-mail and I will send you the installation sheet for you to review.
