Hey, I'm helping my friend sound-proof a room...and need some tip$

Right now, our plan is to buy drywall that is like an inch thick, I'm telling him to do 2 levels of drywall, and have stuffing in between it.

Then the outside I've been looking for cheap egg/wedged pattern foam but the stuff is really expensive once you add it up...

Besides Costco egg crates...has anyone had any luck with any type of material/construction design?

And a good place to buy the material

Thanks a lot!

 

bunch of dead bodies

 

it worked in hustle and flow...

 

on what exactly you are trying to do, there is specially made sheetrock specifically for reducing sound "transmission"- that is reducing the amount of sound that comes in or goes out through the walls, that is one target.

The other item you mention, egg crates or foam, are intended to reduce or diffuse sound reflections within the space- that is a different goal.

These goals are not usually met by the same treatments, properly implemented STC sheetrock involves mounting in resilient channels and stuff, and foam isn't an ideal absorber or diffuser for lower frequency stuff, but there are places to get it that aren't the most expensive- might want to give this guy a call;

If you are really on a budget, hanging carpet remnants isn't a bad compromise that has some limited effect on both fronts, but its not terribly effective on either one.



Here are a couple of links that go into more detail than I can;

Sheetrock is a good idea but for proper sound proofing you need to make sure that you decouple the walls. Do not attach the second wall of sheetrock to the first by any rigid means.

Thanks^ ^^

wow thanks a lot. Yeah its an exercise room...but i'm planning to put a drum set in lol, its our little secret. I dont know if its an advantage but since the room is underground, it has concrete walls about 6' high then dirt/wood the rest of the way. We now have the skeleton of studs against the concrete, so i guess we shouldve left an air gap, since the wood is against the concrete in most places.

It's a basement, so the top floor cant really be modified...but i figure i can do the floor layer example to the ceiling of the room.

this looks good


maybe i'll get some cotton roll to put in between it. And use the foam on the outside ...or inside the room on the wall.

 

I'll ask Ben Afflek what he uses for his hooker killing room.

I mean....dammit!

try to get this stuff... "quash" by Dow Corning. it's extremely light, cuts easily, isn't a fire hazard, and is extremely mold and mildew resistant. you'd just put it between the drywall and exterior wall.

 

psoper has the best info... if you want another little secret, put a small air space between your framing and the cement.

MAss and Decoupling.

 

also at home depot they have these 4 x 10 sheets of styrofoam. we have used them in the past for "sound reducing"

it s cheap meathod about 5-10 bucks a sheet depending on hwo think you get

they have 1.5 inches to 3 inches

if you rent or are on a budget this would be yoru best bet.

if you own there are better more costly methods

 

His Dad owns, but his wife takes all his money lol...so yeah we're on a budget haha

Cool i just got home and saw there is 1"-6" air gap between cement and stud skeleton.

He says the "soundboard" he is currently sold on to work is 1/2" thick and has as much sound deadening as 4" of drywall. I dont know if thats a good way to go or not.

But as of now we will put the sound board on the inside walls, add stuffing, and slip drywall in between the airspace between wall and cement wall.

Thanks guys

 

just make sure that you leave some airspace. if you look at any purpose built sound prrof or isolated rooms, its always made up of a couple walls with airspace inbetween, and nothing is touching the other one.

 

I'm afraid to ask why you need soundproofing...

 

if you read the posts he said he's putting drums in there.

 

we all know it is so kyle can have a room to store his hookers and blow.

-kyle if you need help let me know...
