sound proofing a room with egg box type foam questions

Rich1988 · 17 Feb 2011 at 15:43

Hiya, planning on sound proofing a room/shed type thing, I can get my hands on huge sheets of egg box type foam for nothing and I was just wondering, firstly does it actually do anything to deaden the sound coming in and going out? and secondly whats the best way to stick it to a wall/surface, I was thinking carpet tape?

thanks!

Egg box type foam will treat the sound in a room not sound proof it. Rock wool is what you want.

EDIT: Spray adhesive is best for affixing either.

what are the walls of the room/shed made of ?

Yep was just typing that. It will help diffuse the sound and cut down on some of the higher frequency reflections in the room, but will not do much if anything to isolate the room, which is what your after. Rockwool will help to do this but it's a huge project trying to isolate a room properly. Good luck

Are you trying to troll us Herr Fritzl?

just a smooth wooden surface, Im not actually trying to sound proof it that was probably the wrong wording, just to reduce sound level going in and out of the room the primary reason also being that I ahve access to a **** load of big egg foam sheets

Rockwool tbh, wrapped in a muslin sheet and hung on picture hooks/similar. Or acoustic slaps if you afford it.

You need to build a room within a room:

You can try, but you'll be wasting your time.

Rockwool, used widely in industry and construction projects.

If you want to soundproof, as in to isolate sound leakage into and out of a space, then what you need is mass and good seals!

Heavy brick walls/sand filled wooden cavities or similar, thick doors with good seals and make sure you haven't got a tin roof, you need plenty of mass there too!

Acoustic foam will absorb sound energy (converting it into heat) but the frequency to which it will absorb is proportional to its thickness, so if you want to keep out noise including traffic etc, you'd be looking at metres of thickness.

A combination of both the well constructed room and foam treatment inside for internal reflections is reccomended.

Whatever you decide that's a sweet deal being able to get the foam for free! Is it heavyweight acoustic studio foam or just regular cushion stuffing foam? Studio foam is rather expensive normally!
