I have posted a sound insulation question before a received a lot of
I would like to revisit it one more time. I'm trying to sound insulate a
second floor bedroom from the kitchen directly below it. The bedroom has
3/4 pine nailed directly to the joists.
So I'd like to ask a very specific question. Is there some kind of soft
material that I can add to the kitchen ceiling joists as strips that
will absorb acoustic energy and therefore act as sound insulation (at
the same time not affect the structural integrity of the ceiling drywall.
Many thanks in advance,
In music studios for real soundproofing rooms are built inside rooms
without anything touching, a friend who has built them said a bead of
caulk was used on the studs before drywall was attached, I know a
drywaller that also does this. Im sure any caulk will work, let it
harden first. But this is only the smallest part of a sound deadening
job, double drywall would help more as would other things you need to
research, there is drywall designed to reduce sound and fiberglass
insulation that would be special orders.
As you was told the last time you asked there are no magic simple
answers...Adding soft strips of cloth or caulking will do nothing....I'm
sure others will re-post the same answers as before and they were good ones
but I'm not gonna bother...You already know the answers....You just don't
want to do the work....HTH...
What kind of sound is being transmitted? Did you try eliminating the
source of the sound? Insulating for sound is very specific and the
most effective barrier will involve more than one step. A small hole
along side a pipe will transmit sound, so caulking or using expanding
foam is your first step. Seal around heating ducts, electrical holes,
etc. Then, (loosely) fill the voids with poly batting or fiberglass
insulation. Sound deadening can cost much less during new
construction or renovation. Where I live they test loud sirens every
first Wednesday of the month for 5 minutes (every dog starts howling
too)--annoying but not much can be done here except ear plugs or
