reduce sound transmission between interior walls
 

I've googled this and all the information is aimed at soundPROOFING the
walls. I'd just like to make a decent reduction in the amount of sound that
passes through the walls.

The usual advice is the add another layer of drywall with some insulation
between, put staggered studs so the wall board from one room does not touch
the wall board in the other room, etc etc. All of these make perfect since
and would be very effective at reducing the sound transmitted but they are
major projects.

I'm looking for bang for the buck here.

Right now, I have two bedrooms that share a wall. One has my 1 year old
light sleeper and the other my 3 year old noise maker (toys that play music
and talk). Also both of these bedrooms share a wall with my living room
where the TV is. To make matters worse I have some hearing damage so I need
the TV a little louder than usual so I can hear what people are saying. Not
blasting loud but I can't turn it down to whisper levels and make out all of
the words.

The wall construction is typical with a 2x4 studs between two 1/2" drywall
sheets.

Is there a product that can be blown into the walls through small (say
1-2")holes between the studs, in the top sil (non load bearing sil from in
the attic) or the sheetock itself? I'm thinking of some type of blow-in
insulation to reduce the sound from echoing in the dead space between the
two sheetrock walls.

I've seen several say that when they remodel and put plain old insulation in
there interior walls with nothing else special it made a notiable
difference. I'd like to duplicate that except witout removing the walls.

any ideas?

minimally expanding foam insulation worksa well, but is pricey.

it expands and seals air passages tht allow sound transmission. can
easily be installed from indoors with small holes.

will provide much better sound deadening than blown cellouse, theb far
cheaper alternmative.

perhaps it might be easier to move bedrooms?

Foam might make it worse in some frequencies, its solid, it did for me
and it would not be cheap. Cellulose would absorbe more sound.
Cheapest to try would be hang decorative rugs on walls then blow in
cellolose, then build out if that wont help.

A dense foam should help. Also make sure that you address any
ventilation issues. If you have a forced or gravity air heating or
cooling system, you will find that those ducts can easily defeat any
sound insulation you add. You can address those issues, but just be
forewarned that you will likely need that as well.

An additional layer of drywall will give you the most bang for the
buck as it is cheap, but it will not be as effective as other
measures.

Hit a piece of foamboard even a foam cooler, sound resonates loudly. I
put foamboard on my house, now when the neighbors walk upstairs it
sounds like they are Inside my home. Certain lower frequencies are
acentuated with foamboard. Drywall and wood dont resonate like foams.

Yes. Lots of info at:

http://www.cocooninsulation.com

Got the machine and insulation at the Home Depot. At the time, if you
purchased x number of bags, the machine use was free. I did quite a bit
and it worked out well. Doesn't sound like you may use enough for freebie
use.

I used a hole saw and kept the cutouts. Later I mudded them up and set
back in the holes to dry very slightly recessed. Later mudded over them.
BE SURE to prime these spots before repainting or you will end up seeing
dull circles all over the room.

I don't know if insulating between interior rooms will alter the
heating/cooling transfer.

I think you may spend a bunch of money and find that it only helped a
little. You need hard solid surfaces to soundproof. That's why folks
suggest drywall.

I know these ages can present some difficult sleeping challenges, but
things normally get better over time. It's good to get them accustom
to noises when they go to bed, otherwise you will spend your life
tiptoeing around your house. Kids are really good at falling asleep
when they are tired, regardless of the noises around them.

Take some walks after dinner, go to the park, run around, play. When
you get home do the bedtime ritual, then read to them. Every night.
Kiss them, tell em you love them and turn out the lights. They'll
catch on.

Loose-fill slag wool insulation.

Excellent Sound Absorption
The fibrous structure and high density of rock and slag wool
insulation offer excellent sound absorption properties, making these
products an outstanding part of overall wall systems designed to
reduce sound transmission.

Consider the sequence:
* Excessive sound vibrates the sound-side sheetrock
* The sound-side sheetrock transmits this vibration to:
a: The air between the two layers of sheetrock
b: The 2x4 holding up the wall
* Both "a" and "b" transmit the vibrations to the quiet-side sheetrock and
from there to the quiet room.

Filling the cavity between the two rooms may mitigate "a", but not "b".

I suspect MOST of the sound transmission is caused by "b", so filling the
cavity will not be a perfect solution.

The BIGGEST "bang for the buck" is a set of earplugs. Fifty cents.

I agree with Bob on the white noise generator. We have a 1 yr old and he
sleeps like a baby with his white noise machine and my 2 other children in
the room next to his.
Good Luck!

Years ago, an architect told me about using lead sheeting inside
walls to deaden sound. Lead sheeting should be available from
roofing suppliers but it may be quite expensive. There is a material
called MLV "Mass Loaded Vinyl" that is almost as good as lead.
