Home interior sound deadening ideas?

[frapjap]

Hey guys, I just moved to a new place and all is well, except that the bedroom door is made of that new modern hollow crap, rendering it "thin" and utterly useless at providing a noise barrier between it and the living room. I want to put something on the back of it to help dampen noise, but don't know what would be best for a noise reduction to dollar value. Aside from a new door (which would probably piss off the landlord), I'm at a loss. The sounds I want to block and/or reduce are voices, television, music, etc.My ideas so far:- Carpet. Might work? Remnants are cheap, but it is heavy.- Foam egg crate. Definitely cheap, light, but don't know how effective it is at dampening.- Dynamat- expensive, and would probably have to replace the door later because of the sticky adhesion stuff..- Thick blanket- ::Shrug:: ?

Ideas?

Line your walls and ceilings with dead hookers.

Remove the dry wall and inject foam. Add new dry wall.

[Mr1der]

foam would be the best bet.

drill holes and shoot that dude full.

it'll piss your landlord off after you leave and they find it everywhere.

Walls are fine, pretty decently constructed. The noisy point is the crappy contractors commodity interior door. It passes sound WAY to easy.

Get a thick Persian rug that's door sized and hang it up on the door, get a sweeper for the bottom of the door.

Who do you live with?

[frapjap]

Random co worker. Hes quiet and all, but I just like silence. He could play Tiger Woods on the x box and I'd still hear it.

[Dire91]

Insulation does well for sound deadening if it isn't already in your walls, thicker dry wall.

ITS FOR THE DOOR

Haha, I thought I was the only one that read the original post.

How do you figure? That s*** is an upgrade. If they do get pissed, just keep the old one and swap it on if/when you leave.

A buddy of mine has tried the egg crate foam on his door, inside and out. It didnt make much of a difference.

[Kelbizzle]

Ear plugs = Problem solved.

You're welcome.

Edit: I meant that in the nicest way.

This. Your basic home depot stuff should do pretty well.

[MinisterofDOOM]

You should be able to inject expanding foam into the door without making any new holes if you remove the door handle. Or, at the very least, you can keep the new hole hidden by removing the handle and going in through the latch hole.

You could also drill holes in the top of the door where no one will see them (even mud and paint over them after if you want) and fill with foam through them.

Having dealt with helping work on a sound studio i'll chime in here.

You have two issues:

Weight and air gaps.

The way we took care of this in the studio was to use and external weather sealed metal door for the entry to the studio.

The ones that have the seal all the way around. These stop a huge portion of sound right off the bat.

New doors are typically "foam core" doors already. So they're already full

Check out Owens Corning OC703. I used that to make some acoustic panels for the house. They are most efficient in the vocal range.

the majority of new interior doors are hollow with luan faces.

ray, take the door off the hinges, drill a hole in the top or bottom, or behind a hinge plate, and fill it with foam. if you get the expanding s***, go slow. let it expand into the available open area, you don't want to rush and have it press out on the faces. then line the top and sides of the frame with foam strip, something like the foam barrier between a radiator and the core support. finally add a sweep to the bottom. that should do it. if not, get rid of the room mate.

Eww... the ultra cheap ones. A pack of 10 for $100 I've accidentally put holes in those before...

Unfortunately this will not do much.

Expanding foam is a closed cell foam. This will not absorb sound nor will it add enough mass to stop sound.

Are you renting this place?

Typically the frame is crappy too. If you don't mind putting money into this, change the frame and the whole door. As long as it looks like it did before the landlord wouldn't know the difference.

that's typically what's being used these days

it'll do enough to drown out the majority of the sounds he's trying to eliminate.

he is renting, so i wouldn't advise him to start changing frames and the like. landlords don't like the tenants making modifications to their property. depending on how the lease is written, he could at the very least lose his security deposit.

indeed, it's better then nothing.

I recommend these:http://www.atsacoustics.com/it....html

I purchased a pack of these awhile back.

Cover them with this:

Place one and a half on the door. Then use the rest where ever you can. They work great for attenuating vocals and midrange noises.
