Sound control for a small bedroom?
« on: November 17, 2013, 08:36:58 PM »

I have a simple 8x8x9 bedroom that I wish to manage. Above is a model of the room. This was done in Photoshop.
It may be a tad off here and there but otherwise it's drawn to scale. Some things to note however...
  • My door is hollow-core
  • My walls are simple drywall with wood paneling on them.
  • I do have carpeting already instead of wooden floors
  • 3 of the walls are simple drywall, only 1 has insulation (Outside wall)
  • There is wood paneling atop the drywall that's simply nailed to the wall itself

Note: I only have a very very limited basic understand between acoustic absorption and noise isolation. I do believe I want the latter as best as I can, however I realize without building up new walls or removing my current ones it won't be 100%, just looking for the best improvement over my current situation as possible. So far from what I've looked up replacing my hollow-core door is the main suggestion. Just getting a new solid door slab and making it air tight. Other than that I've been told to rip up the walls or simply to staple carpeting to them.

Door I'm currently looking at:

To make clear I cannot remove the walls/paneling/drywall at all. It's there to stay. Carpeting some people suggested a few times. While I've no idea if it'd work or not I have no interest in carpeting my walls...I just feel like it'd be ugly and look weird. Others have constantly recommended egg cartons but 10 minutes on Google quickly dismissed that idea as a myth. That being said what I'm trying to achieve is a way to keep the noise that goes on in this room? To stay in this room. Be it noise from the TV/Movies, Computer games, Music, talking on a phone or in person with someone else in the room.

Below you'll find 4 pictures of each wall and what space I have to work with to be viewed with the model above
(I apologize for the quality)

North Wall

East Wall

South Wall

West Wall

Again to note, I realize due to the conditions of the room and not being able to remove any of the wall or build new ones, that 100% sound proofing the room is not possible. I'd still like to keep as much noise that goes on in here though, to stay in here.

based on the limitations you have, the best bang for buck will be to add mass loaded vinyl / green glue and a new layer of 5/8" drywall to the wall...
It all comes down to mass....if your trying to block sound the options are to decouple from the structure and add mass....
Since you can not decouple ( removing drywall and installing clips and channel or new framing) all that is left is to add mass and dampen.

If you can not add additional mass to the current walls you are not going to see a viable reduction of noise transmission.

So in otherwords...I'm screwed when it comes to isolating the sound in this room.
Everything in here is a pretty close fit and there's really no available space to add new layers of drywall..

Shame they haven't invented something you can easily and simply apply/hang on current walls that blocks sound  :-\

well if you can not add 3/4" to your walls than I would agree with that statement..
There are products to just simply add to the walls that would give some value, however your asking me for bang for buck options...there's the catch 22 someone who works in the field as well I personally would not hold my breathe on viable reductions if you dont at least double the mass value..

Mass law stats that you have to double the weight of a partition just to see a -5 decibel drop...(roughly 40% reduction)..excluding bass and impact.
