I have a condo that shares a wall with the unit next door. I can hear their
dog barking very easily. Would this method work?
* Install 1/2" Soundboard (from Home Depot) over existing sheet rock
* Install 5/8" fire code sheet rock over Soundboard
I've read that it's best not to use nails, but I might have building code
issues that I'll have to adhere to. Is there some method in which nails can
Thanks for reading.
If I understand what soundboard is I don't think your plan will help
much. A major source of sound transmission is conduction through the
structure (wall studs), so one of the main thing to do is isolate the
wall on your side from the structure. Roam around these websites and
see if you find anything.
There are some special Z shaped standoffs you use to install/attach
the wallboard with isolates it.
Take a look at this page.
I'd not like to be your helper as you install 190# 4x8 sheets though.
By way of comparison, from my "Gypsum Construction Handbook" the STC
rating (a weighted attenuation) of a wall with 16" oc 2x4 studs and 5/8"
drywall on each side is 46. Two layers of 1/2" drywall on each side,
with one side's drywall mounted on resilient channels and a 3"
Thermafiber blanket in the cavity takes you to an STC rating of 59.

All this will be for not, if that sound is going around the wall via the
attic or through it via some heating openings.

Why not squirt polyurethane foam into the cavities? There are companies that
specialize in that. Might be worthwhile to get a quote. HTH
That will block high sounds, but do next to nothing for low ones. You
need mass (concrete, sand, ...) to stop sound.
And sound is somewhat like water; if there's a hole (air vent, duct for
wires, etc), the sound will go through it.
As most amateur musicians can tell you, soundproofing a room is a
