Okay so...calling all handymen... I am getting a little studio going at my place, and need some advice. I want to create a corner for recording vocals, I've seen it done before where people put Egg-container like sponge on the wall for sound deadening purposes. THat particular studio produced a few cd's available on shelves. So I want to fix this sponge to the wall, I however want to do it in such a fashion as to not tick off my landlord and I also don't want to repaint when I move.
Initially I thought double-sided tape will do the trick, but the sponge is too porious...one idea I had this morning is a dollop of project glue/ contact adhesive on the sponge side of the double sided tape. The viscosity of the glue might just penetrate the sponge better.
Ideas gentlemen?

Make free-standing flats. You can then move them around the room to get the best acoustic treatment. Also you can place them across 90 degree corners which are serious offenders.
Nitebob
That would actually be the best way to do it...sponge can be thumbtacked to the board...thanks Pete...
Ultimately one can make four boards and have a enclosed recording 'booth' ?

+1 on free standing flats for close work and to help with isolation - you can pick up some office dividers secondhand and modify those. The best stuff to use is the rigid fibreglass or mineral wool - it's actually a better broadband absorber than most of the foams, just doesn't look as good, so you need to cover with speaker cloth or hessian.
You can also make some tube traps (simple to do, just Google "DIY tube traps"), which are also free standing and also work even better in corners. Your absorbers work best if they are spaced away from reflective surfaces though, so build a few panel traps too (simple wooden frame, rigid fibreglass or mineral wool inside and speaker cloth or hessian over the top to make them look good) and you can mount those on the wall with a pair of screws.
BTW, never use double sided tape for anything on a wall - after a while it sticks to the wall so well that you take a lump of plaster off when you remove it.
Of course, a simple option for vocals is to get an Se Electronics Reflexion Filter...

Embarassed to say I've never heard of Tube traps, read up now. Very interesting. Thanx Alan

+1 to all Alan said.....also that SE Electronics Relexion Filter is great...and they are well priced.....We're getting one soon for our next album project.

We do a lot of acoustic paneling for auditoriums and large halls etc. We use the "wool" Alan is talking about. It comes in a roll, 1,2m wide and R50 per meter. And like he says, its not pretty, so cover with hessian. Preferably black. You can get at Metro Home. About R28/m.
Nitebob
Hanks for all the advice guys, will throw it all together and see what we come together with.

BTW: The topic should be "acoustic treatment", not "sound proofing". Two very different things:
Acoustic treatment - controlling reflections inside a room so it sounds better
Sound proofing - controlling the amount of sound entering or leaving a room, which is more construction-based.

Oh yeah, if you want that accoustic wool, its sold by a company called "Brits Nonwoven"
Mo-Facta
For interests' sake, here is a table of the absorption co-efficients of different types of materials:
The higher the coefficient, the more of that frequency it absorbs.
Cheers ?

The stuff we make looks like this. It has the wooden slats and the acoustic wool and Hessian.
A bit of a combination of different options.
And then also the sound absorbing acoustic ceiling boards also used on the dome:
Nitebob
Thanks for the pics Jacques, looks very neat when done that way... ?
AlanRatcliffe
Very nicely done - looks great and - probably more importantly - able to withstand thousands of people a week. ? I love seeing acoustic treatment where it is as much artistic form as function.
What wood are you using for the slotted traps? Looks really good! I like the diffusors too - any specific reason why you used them on the side walls rather than the more usual rear?
Is that more slotted trapping up near the apex of the dome, or is it more to blend in with the theme, like the metal/wood structure below the dome.
PeteM
Super cool Jacques. I wish more venues would this and I suppose you do as well. ?
