i am definately going to do this.

now imagine lets say 6' high and 4' wide as a "u" shape. i do it correctlky and have 3 walls all symetrycal, and i put another on top to make like a small isolation booth thats portable.

would it be worth making???

also this whoel thing can dissasemble to possibly even put hinges on the 3 walls, and have the roof part just sit ontop, and i can use the 3 walls as a drum isolater.

could all that work???


the thing thats scaring me is the fact that its a peice of wood.... how much is this honestly gona do?!?! should i put studio foam on the inside of this small isolation area??? or nto bother

What are you trying to accomplish? That link is to a fiberglass bass trap and they are made to work up against a wall. If you just want a more dry recorded sound then placing panels like that close to the source and close micing can help.

If you really want to block sound then you need something heavy like wood. It can help seperate different mics but it's not going to completely isolate anything.

i was just taking that design idea. i dont think tis fiberglass, i think he did use wood. but anyways what i planned to do was

make the same aluminum casing, with plywood [1/2" thick] and make the box, and ont he iside put actual insulation or the steel wool and fill it up, and make 3 pannels 6 feet tall, 3 feet wide, and make a 3 feet by 3 feet peice to attatch on top. and then on the inside i would attatch 2"-3" studio foam on the inside of the iso booth [persay]

would that be worth the time/effort? it would ony come out to like $120 for me cause the only price i'd really be paying for is the casing and the foam, the wood is free because my uncle is a carpenter.

i think you are misreading that. he is not using plywood at all, just the fiberglass. The point of the corner bead aned no wood is to allow maximum access to the fiberglass from all sides.

You can make items with a thin plywood panel, that are "tuned" to a certain frequency, but what you want to do is just tune the room and you can;t do too much bass trapping. No need to overdo this, just handle bass trapping with those panels and stick them in the corners maybe float one over your mixing station, use a few 2 inch thick versions at your key reflection spots (the areas behind your monitors usually,and various spots where the monitors will be putting out noise that is likely to bounce off walls in a manner that presents phasing issues).

Isolation (keeping your noise in, and other noise out) is done with mass, and sound will vibrate through and along materials. True isolation involves "floating" walls and floors with gaps between to avoid sound transference.

But if you want to compromise and put together panels that can be constructed into a booth like thing you will get a compromised isolation, less than you would get without, but you probably won't get amazing results, it is jsut to hard to get true isloation.

alright thanks.


idk i think im gona try and put this iso booth together. see hwo it goes. i need something to put togetehr anyways for vocals, and somehting portable liek this is perfect. maybe even configure it differently and put all 4 side's and put hinges on the 4th side and put a lock on the inside to close.

idk i have so many idea's in ym head for this.

i just need somehting for my vocals. i was also thinking, to cut a small hole in the side to have the mic hanging in [about a 1 inch hole to fit the mic stand boom into] then with the 4 side's, insulation in between the 4 walls, and the studio foam on the inside, it'll definately help wiht isolation. i can't see it not
