Soundproofing a room

I am converting one of my bedrooms into a nursery which I would like to soundproof. Currently, the wall is 1/2 inch drywall attached to studs. No insulation.
I am reading a lof of different suggestions with each one saying the other one is no good.
I want this room to be soundproof so a baby can sleep without being disturbed.

I read put insulation in the walls won't do much. Adding a second drywall will do nilch.

What can I do to soundproof a room so the rest of the house does not need to walk on eggshells when passing the baby's room?

first I will say that when our boys were little we didn't want to walk on eggshells either. our solution was simple "don't" what we found was if you walk and talk normal they get accustomed to the back ground noise and it won't bother them.

Now if you are wanting to make the walls sound proof, can you? well probally not totally but there are things you can do to deaden the sound. accoustic pannels that are mounted to the wall, these will help dull the sound. something that will work better is to strip the drywall off the wall and insulate the wall with unfaced insulation (faced insulation can act as a speaker towards the side the paper is facing) then use resilient channel that is available from your drywall supplier like csr rinker(probally not available from big box stores)after you install this then you can hang your drywall on it making sure you use the proper screw length so that screws don't penetrate the studs. also makeing sure the "open side or side that isn't attached" is facing up this allows for movement. click on this link and go to the picture on the bottom of the page and you will see it.

keep in mind this will only have limited effect because of other factors, such as your door to the room duct work and any penetrations (such as elec. boxes)through the drywall.

a lot of work, I still think your easiest is just "don't walk on egg shells"

besides that walking on eggshells makes a big mess.:)

Re: Soundproofing a room

Several years back we put in a sound proof room in a comercial project we were working on. We installed a double layer of 5/8" sheetrock. (one layer vertical, the other layer horizintal. I cant remember if we taped the inner joints or not.) We also installed a solid core door. It really was soundproof. Atleast as far as we could tell.

That being said. I wouldn't soundproof the room to keep a baby asleep. It's been our experience with our boys that when they need sleep they take it. I've seen babies sleep through all kinds of noise including band practice. I think I would take the money you would spend on sound proofing and get all the other baby stuff you're going to need.

Re: Soundproofing a room

I am planning to soundproof all the bedrooms. I am starting with the baby's room.

I have read a lot about resilient channel , but I have no clue what that is? Also, you mention "the proper screw length so that screws don't penetrate the studs". Don't all screws penetrate the studs to hang the drywall? How else would you hang it?

you mount the resilient channel going across the studs then you screw the drywall to the channelso for 5/8 drywall you would use one inch screws. if the screws go through the channel and into the stud this doesn't allow the channel to move to absorb the sound. if you are trying to really cut the sound then you can also buy accoustical caulk and you caulk all penetrations like where the board meets the floor, around electrical boxes and is even rated to caulk the holes inside the elec. box.

Re: Soundproofing a room

Can I used Furring channels instead of resilient channels?

Re: Soundproofing a room

you could but it wouldn't be as effective. resilient channel works like it does because it allows the drywall to move independently of the wall, of course you know that sound moves in waves so resilient channel allows the drywall to move with those waves to an extent and thus absorb them. furring channel would simply deaden the sound by makeing the sound travel through more product. so it would have some effect but not as well. so it all comes down to how much sound are you trying stop.

My concerns with Resilient Channels if someone bangs into the walls, would the wall move? Would the corners come apart? Will paint break?

Also, were can I purchase Resilient Channels? Home Depot and Lowes do not sell them.

I know it seems like it would, but it really isn't that much movement, and no it won't break at the corner or crack as long as it is properly finished. when finishing any inside corner you should use paper tape not mesh tape. this holds the corner more firmly and less likely to crack. making sure that you thin down the mud so it sticks good to the tape. corners come loose because of either too long after putting the mud in the corner before putting in the tape or too stiff of mud. so any resulting cracks are usually due to taping procedures and not due to movement of resilient channel

Can you recommend a place to purchase Resilient Channels? Home Depot and Lowes do not sell them.

Re: Soundproofing a room

you would have to go to a drywall supply house. I live in the south east and here we have csr rinker and seacoast supply. if you look in the yellow pages under "drywall contractor supplies" you should find everything you need there. you will also find you can save a couple of dollars per sheet on your drywall and produts there
