I don't know the first thing about it, but on most pictures of recording
studios I have seen, there appears to be a gray foam rubber on the walls
that looks like egg crate.

Start Googling, and I bet you have a good idea in less than ten minutes.
Then get your input from the other newsgroups and pick yer pony.

There are many good web sites, and you can search the newsgroup's
archives for many threads on the topic.

In a nutshell, sound travels by different mechanisms and the best
method(s) for your particular situation will depend on the noise
source, the current construction and location, and where you are
trying to reduce the sound level.

Build a isolated dual wall system using 2x4 studs on 2x6 top and
bottom plates, frame the "outside wall" oc 16 inches like normal,
frame the "inside wall" oc 16 inches but offset the first stud by 8
inches. Drywall out and in with 5/8 drywall, some add another layer
of drywall in the middle cavity fastened to the backside of the
"outside" wall. This is the only reasonable way to isolate a room.
Mass and/or mechanical isolation stops sound (not foam). Foam is used
to treat reflections and absorb bass modes within the room. As for
the "gray egg crates" mentioned in another post, real egg cartons are
a fallicy seen in movies, they do nothing and are a BIG fire hazard,
wont pass inspection. Open cell polyurethane foam is also a HUGE fire
hazard, actually worse than egg cartons. The only class A fire rated
material excellent for internal reflection control and for controling
bass modes and boominess is rigid fiberglass panels (google Manville
rigid fiberglass, whispertone, etc). Buy the rigid fierglass, cut
panels, and upholster the panels in your favorite decorator fabric
with a hot iron and spray glue, then hang them strategically based on
SPL measurements taken with a tone sweep generator and real time room
analyzer till you get flat frequency responce in the room. Another
thing to consider is the heating duct work to the room if you have
forced air heat (and AC). This will be the biggest nuisance, a
heating contractor can flare the ducts to be quieter and isolate the
furnace vibration from transmitting into the duct work. Also google
"resilient strips" for hanging the ceiling drywall if you want to
soundfroof the ceiling from the joists, again isolation is solving the
problem (not foam or insulation). Google how to build the dual wall
system I described above, it works great and only adds 2 inches to a
wall thickness. You could put insulation in the walls but it will
have little effect, however isolation and/or mass works best, so a
dual wall with 5/8 or 3/4 inch drywall gets you more bang for the buck
than insulation, a third layer of drywall in the cavity will make it
super quiet.

I have a home recording studio too.

I built a home studion in my previous house.

What you want to do is isolate the room from the house. In effect, a
room inside a room. To simulate this, I used resilient channels to hang
a second layer of drywall offset from the first layer of drywall.

Used acoustic tile above with insulation batting above the tiles.

Last but not least, get a solid door - not a normal hollow slab door.

Double staggered stud walls, packed with Roxul Safe and Sound rock

Green Glue. You use two layers of drywall with a bead of Green Glue
between. It dampens vibrations. I don't think there's another product
like it.

Spray foam insulation to stop all air exchange, air movement carries
noise.

theres special drywall that doesnt conduct sound..... and special
acoustic tiles too.

there are pros that design such rooms.

care should be taken some foam is highly flammable

Are you trying to keep sound from coming in from outside, or keep the sounds
you'll make inside from annoying others outside, or both?

Either way, low frequencies usually cause the most trouble. Try to uncouple
instruments (or amplifiers) and mic stands from the floor, chunks of thick
(and dense) foam underneath them helps. I've seen people hang carpet on the
walls to absorb sound, stuff windows full of foam and so on. But those low
frequencies don't care much, it's like bone-conduction, it seems to come
right through the structure of the building. You'll also probably want to
deaden the room a bit to keep sound from bouncing around too much, carpeting
and thick drapes helps a lot with that.

It's worth noting that professional studios are either purpose-built or are
extensively modified for that role, there doesn't seem to be anything like a
"spray on" solution. Lots of ideas out there however....

Yes. Since I need to replace the drywall, I was only thinking about
soundproofing the room from outside noises for now. I can address any
acoustic problems within the room as needed.

Thanks for those tips and web sites. I was hoping for some web site
recommendations instead of using google and hoping to click on the
right links for what I need.

Right now I am focusing on blocking sound from outside the room. That
includes automobile noises from the road, AC and central heating
noises, tv noises from the downstairs living room and ceiling fan and
other noises from the bedroom underneath the studio.

I am not looking for total perfection but to block out most of the
noise with the construction and using other methods like shutting off
noisy appliances when they pose a problem.

100 people were killed in a matter of minutes at the Station Night

That was open cell polyurethane foam panels (like Soundex and Audex),
it flash burns like cellulose. Best solution is upholstered rigid
fiberglass, which has much better acoustical properties anyway, and
you can make panels yourself.

I remember reading up on that in the 1964 Britannica. First seal the
holes, then install an inner wall acoustically isolated from the first.
They said two layers of plate glass could be pretty effective.

Green Glue is different. It works like the mat under the carpet in a
car. First you have the metal pan, then the mat of heavy insulation,
then the carpet. By pressing against the metal, the mat dampens the
vibrations, and that gives you a quiet ride.

You squirt a bead of Green Glue in a pattern on a sheet of drywall and
screw it over your existing wall. With the Green Glue to dampen
vibrations, you don't have to worry about sound transmitted through the
screws.

Not true. There were at least 4 useble exits. The problems we 1)
Initially everyone thought the fire was part of the show. 2)The fire
completed engulfed the palce in a matter of 4 or 5 minutes. 3)Most of
the crowd, even those near other exits all stampeded to the front door
where they had entered. That quickly resulted in a doorway filled with
panicked people stacked up and wedged in the doorway.

There was a crew there, filming a documentary about nightclub safety
(!) of all things. They have photos of the front entrance with all the
bodies, dead and alive, wedged there.

The people farthest from the front door, and near the stage when the
fire started were within 10 feet of an unlocked fire exit that was
ignored by most of them, including some of the band.

lesson learned: Whenever you are in a crowded public space, make sure
you immediately figure out where the closest emergency exit is
located. Finding it in the middle of chaos and darkness may be
impossible.

I used to have Soundex and Audex foam panels in my studio, I ripped it
all out after that fire, now I have all rigid fiberglass upholstered
with nice some fabrics my wife selected. They look a hell of a lot
better than urethane acoustical foam too. The fabric was applied with
3M #90 spray glue then I ironed it flat while the glue was still wet
under the fabric. This permanently bonded the fabric to the
fiberglass very tight and flat. Washing the fabric in a highly
concentrated mixture of 20 Mule Team Borax (no rinse) also makes the
fabric itself fire-retardant.

Thanks for the tip on some of the foam being highly flammable.

I will check into different types of drywall and insulation.
100 people were killed in a matter of minutes at the Station Night
Club in Rhode Island a few years ago when acoustic foam that was not
rated fireproof, caught fire and burned VERY QUICKLY and emitted toxic
fumes. (google for details) The safe stuff is more expensive.

Probably had knob and tube wiring inside the foam. ROTFLMMFAO!!!!!!!!!!!

Not terribly funny to the friends, family and parents of those who
died so horribly.

They're not likely on this group.

I'm one of them
