DONT WORRY! just another thread about vox booths...haha

[Rawbzilla]

So i have an Iso booth in my studio (a room in a band practice facility) but its pretty poorly built not my job btw, (one layer sheet rock, r19, and another layer of sheet rock) it really doesnt block ANYTHING out, someone told me that an "ALL SOUNDBOARD"(4 - 7 plies of soundboard...also, what is soundboard?) iso booth is the industry standard, now obviously, this is not a very educated statement because if it was the industry standard, people in the industry would do it right? ive been in music production and recording for over 14 years (im 21, yes...i started very young) and ive always heard this: "a layer of sheet rock, rubber spacers, another layer of sheet rock, r19, foam, r38/39, two layers of sheet rock" which one is more accurate? or at least, in your honest opinions, and also, what could i do to deaden by vox booth without tearing it out or building another one inside of it? i have tons of foam but most of it is the egg crate kind, i only have ten, one foot squares of auralex, and thats already spot treating the control room. any help is appreesh. by the way, the dude who was in the room before me apparently was angry that he couldnt take the iso booth (even though it states in the contract BUILDING MODS WILL STAY IN THE ROOM IF CONNECTED TO WALLS) so he decided to take a hammer to the only wall not touching another wall or with a door on it, meaning, my left wall has a hole in it, and he tore the foam out, and the door has been removed too (temporarily replaced with a foam filled metal door)...so, before i go to the depot and buy a door and frame, what should i do? double the room? and what kind of door should i use? also, where can i get this wonderful "soundboard"?? thanks for any help guys!!!

There are lots of places that will sell you expensive stuff to improve isolation. However most of the specialized stuff isn't cost-effective. In other words what you could spend on fancy spacers or 'soundboard' would get you more on just another layer of gypsum board.

So the standard is a double stud wall with two layers of 5/8 inch gypsum board and a layer of R-11 fluffy stuff inside to cut resonances in the airspace and a floating floor. But just as important as that is paying close attention to the caulking, penetrations, seals, and ventilation. They will get you just as much as not having enough mass.

Since you already have a single stud wall that you want to work with your best choice is to take off the drywall on one side, add resilient channel, and then put two layers of drywall up, again being carefull to caulk well and limit any penetrations and plan the ventilation carefully.

As for the door you want a solid core door (ideally two) with good seals all around and limited penetrattion by the door hardware.

You will need sound absorbtion on the inside of the booth to keep down the boxy echoes, but bear in mind that this does not help the isolation, it just cuts down the echoes.
