Acoustic Curtain over drywall?
« on: January 26, 2012, 06:28:36 PM »
I have a flimsy common wall in an otherwise well-built condo, and i need to keep the sound of my crying baby from leaking into my neighbor's bedroom. 

The common wall hits the exterior wall between two windows, so I know it can't be more than 1-2" total.  I think this means it has little to no stud or interior space in there - most likely it's just two pieces of drywall stuck directly together.

I think the lack of studs or interior space in this common wall renders most of the sound proofing options unsuitable, and i don't really want to contemplate collaborating with my neighbor to tear it down and re-build it correctly.  Also, the window placement might make that impossible anyway.

I've seen a damping material that can be applied to the wall and painted, but i have serious doubts that it could dampen the sound enough to keep a crying baby (approx 6feet from the wall) from disturbing my neighbor, whose bed is on the other side of the wall.

What about hanging a giant acoustic curtain in my child's bedroom?  Perhaps I could put a fun fabric on the outside so it is more child-friendly.  Would that work well enough?  Any other solutions that don't involve rebuilding the wall?

thanks!

To be honest, the curtain is an expensive approach for the little reduction it delivers... 10%-15% at Best!!!...
Sounds like you will have to address the wall correctly and most likely do a window treatment as well.

You might be able to get a decent value of reduction by adding mass to the wall but that would depend on the actual construction and if can support additional weight.

Why dont you give me a call at the office and lets discuss options...
