Soundproofing a Snorer
« on: February 14, 2006, 03:42:46 AM »
I live in a duplex condo with my bedroom on the same wall as the neighbor  and the guy in the next condo snores so loud he wakes me up during the night.  The soundproofing is supposed to be superior....."Wallbar" blown cellulose soundproofing.  any information/help would be appreciated.

Probably the most common misconception about soundproofing - that if you fill the walls with insulation, the noise problem is magically solved.  The cellulose (or fiberglass) will only dampen the sound that is bouncing around inside the wall, not the sound going straight through it.  For that, you need more mass or decoupling.  The easiest thing to do is to put up another layer of drywall.  That will give you a few more dB of isolation.  If you want to mostly eliminate the noise, tear off the existing layer and mount 2 new layers of drywall on resilient channels, or channels + clips.  Also, remember to seal up gaps and penentrations - where the bottom/top plate meets the floor/ceiling, the edges of the walls, electrical boxes, etc...  
Some of his snoring noise will still be coming through the floor and ceiling, but a lot less.

Here is another idea from a customer who actually installed the following over the wall in his apartment AND it greatly reduced the noise between rooms:

1) Buy a grommett kit
2) Use 54" wide MLV with adhesive backing
3) Install 3-4 grommets about 1.5" from the top edge of the MLV
4) Remove 48" of the backing to expose the adhesive
5) Apply 2 strips of 24" wide x 94" long Acoustic Cotton Fiber Insulation over the exposed adhesive
6)repeat 2-6 until you have enough panels to cover the width of your wall
7) install the panels such that the 6" area covered with the adhesive backing overlaps 6" of the MLV with Cottton Insulation
Hang the MLV panels over your wall with the MLV against the drywall

This should muffle the noise enough to a tolerable level.

Take a look at the spec for the MLV:

Here is the spec for the Acoustic Cotton Insulation:
