Soundproofing pipe noise in cinderblock wall from 70's
« on: April 17, 2014, 09:08:49 AM »
Hi, I'm new here!

I have a small flat in which I'd like to re-purpose a kitchen into a bedroom. The room in question has a shared wall with the neighbor's kitchen. The shared wall itself is constructed out of cinderblock, and was likely covered with 10-sand:4-lime:1-cement mixture after construction. Through that wall, metal pipes are running, used to bring water to sinks positioned approximately at 1/3 (neighbor's sink) and 1/2 length of the wall (sink on my side of the wall). I am in good relations with my neighbors, but I don't believe they would be willing to change something in their kitchen, since that would be very disruptive to their lives (I haven't asked).

Here's a sketch:

Code: [Select]
w: window
s: sink
=: cinderblock

|
|     neighbor's room
|
|          s
================ <- pipes inside
w      s
w
w    my room
w
|

When my neighbor uses the sink, an unpleasant and sometimes quite loud hissing sound can be heard. Occasionally, the clanging of pots in the sink can be heard as well. This is not very noticeable during daytime, but could be important at night.

On one side of the room, I have windows all the way to the cinderblock wall. There are 1, 2 inches max of possible thickness added to the cinderblock wall to spare before the windows are obstructed by the extension on the windows side. Since the sounds will likely be bothering us if we are to sleep there, we have been considering adding a to-the ceiling closet that would stretch to 1 meter from the windows (making it possible to open the window pane). That closet can hide some thicker insulation. If that would not be helpful, then we might prefer to position the closet elsewhere in the room.

Code: [Select]
w: window
s: sink
=: cinderblock
c: closet

|
|     neighbor's room
|
|          s
================ <- pipes inside
w    ccccccccccc
w
w    my room
w
|

How can I best acoustically insulate the sounds in question so that I can enjoy a peaceful bedroom? Thank you!

The best thing I can think of is to use our clips and hat channel with r-8 insulation between the channel and attache 5/8" drywall to the channel leaving the 1/4" gap around the perimeter and seal with acoustic caulk.
Here are the links.

if you do not decouple you will not see the noise reductions your looking for.
