Reduce Impact Noise - Concrete common wall
« on: March 04, 2015, 11:42:09 PM »
I have a semi-detached house which is separated from the other unit by a concrete block wall.  It appears that wood strapping (about 1/2 inch) is attached to concrete and then drywall is attached to the strapping.  The gap between the drywall and strapping is hollow - no insulation.  My main problem is with low frequency and impact noise from outside door slamming or stomping on stairs.  The house is narrow and I don't want to lose much space.  Would applying a new layer of drywall on top of the existing wall  something like green glue (and perhaps a layer of MLV on the back of the new drywall) help much?  Thanks.

sorry to say but footfall/ impact noise will always go to the area of least resistance and depending on how the floors of the units are constructed the noise issue might just go under the wall, therefore adding soundproofing to the wall might not help at all.

Give me a call direct and lets discuss the particulars to see if we can come up with a viable solution.
