Does anyone have any experience with soundproofing a room?

I am moving house and I have a room I want to put decks in measuring 315CM long (⬆⬇ ) by 235CM wide (⬅ ➡

The goal: I want to blast music quite loud without offending neighbors and the wife.

I read about 'a room within a room' which seems like overkill to me. Also not sure if hanging carpets off a wall will make me seem like a sane husband.

I cant see any other way of doing it other than this 'room within a room' concept. Open to ideas or suggestions

Yes, I can help (I used to own an acoustics consultancy) and last year did an entire 2000sqft fully soundproofed facility from the ground up.

It really depends how deep you want to go. At the last you need to decouple the walls form the studs but you could go all the way to resilient channel and floating floors.

Gimme an idea of budget and how much work you want to do and I'll try to help.

By the way, you're going to be better off posting this in the Prod forum but we can probably ask Lira to move it.

Happy new Year!

Sorry for late reply. It seems the walls are concrete and provide a lot of isolation anyway.

A room within a room is not realistic so i'm not sure what options that leaves LOL I am open to anything

Sorry I didn't see this either.

Concrete is good for isolation, horrible for reflections (i.e. it will sound like shit for you).

If the walls are raw concrete then you have a few options:

1, Leave it and just have some soft fabric, even rugs or fabric based wallpaper over it to kill a little of the first reflections and dull the hi's.

2, Put drywall on it - With this you're essentially doing a room within a room but it's not as difficult as you think. You're really only taking 4" deep away from the concrete room as such.

if you're going to do that, the it's better to frame (2x4) around the walls, then do single leg resilient channel, add some insulation. It's not difficult, would probably only cost you a couple of hundred (plasterboard is 7 quid a sheet from B&Q), and then a few days labor (probably 3-4 if you do it yourself, maybe 2 if you hire trades).

The weak point in isolation are going to be the ceiling (for noise to the floor above) and any windows/doors, but those are pretty easy to isolate.

let me know what you're thinking and I can give exact directions on how to do it, including links to what you need.
