Iso Booth Budget and Plans

[halo206]

On my ceiling i have fiber board and drywall screwed into wooden studs. If i constructed 4 walls using the resilient channel method, would it have absolutely no effect on the sound isolation because of the ceiling being rigidly connected to the framing of the house, or could it possibly work pretty well? My floor would be conrete with carpet layered over it, btw. Maybe if i take extreme care in making sure the room is completely isolated?

Also im still wondering what the best choice for fiber insulation is when trying to build an isolation booth?

Thanks,

Hello!

Thanks Innovations! for the reply. Its kind of ridiculous how many posts ive read of arguing about isolation. I was actually hoping to avoid that, but i guess it wasnt meant to be. I just wanted to know in my situation how i could reach the best sound isolation as well acoustics, within a tight budget. Anyhow are you saying theres no way i could reach any level of isolation with a 300$ budget, or are you saying with my roomsize its impossible? If it can be done i guess i would be forced into spending the money to do, as this is something ill be doing for the rest of my days (as i have it planned so far) Or maybe ill just buy some more fiber board, 5/8" sheet rock, plywood, and some 3" acoustic foam and go nuts.

Thanks for your help,

Maybe an analogy would help.

Lets suppose you wanted to make a swimming pool. But for some reason two sides of the swimming pool have to be wire mesh. Not to worry! just make the other two sides really, really, really watertight. Buy you know that making the other two sides really watertight isn't going to do it if the other two are mesh. Sound is like that. It will escape through the wall that gives it the least resistance Walls for isolation heed to be heavy and sealed. Once you said that you couldn't build real walls on those two sides you were in trouble.

Now the most typical approach to take where you can't build anything is to build a freestanding vocal booth. Done well you can get maybe 20-30db of sound reduction. Now if what you are trying to record inside is not very loud (vocals. accoustic, violin, etc) and what is outside is not loud then that quantity of reduction may be enough and building a 4x4 freestanding booth for $300 in materials is within reach.

But when you said drum sets 2 things happen: First drumsets are loud, so the quantity of reduction needed for a vocal booth will not cut it. You need beefier leafs. Second, they are big so you will need more than a 4x4 booth. Both of these mean that your trip to Home Depot is going to set you back more than $300.

I am prepared to do what ever i have to get the best results i can. I understand that sound will escape, but i was wondering if it would have absolutely no effect on the isolation in the situatuation described above. Ill take your answer as being "no".

So what can i do to my ceiling to isolate it as best as possible? Lets say i have 4 walls that are permanent with studs, fiber iso, rc metal, and drywall on both sides. My ceiling is 85" tall, what should i apply in order to get the greatest effect while maintaining some of the headroom.
