my room for my studio is 18' x 14.5' x 8' i would like to have a vocal booth, control room and live room. play about 80dbs. With that being said is my room too small to do this? i've been working in sketchup to do this sorta. I have 1" foam and 1/2" osb on floor. starting to put mass in joists now. have HVAC ducts running in the room that i will remove and replace and one pipe running up back wall for radon exahust. budget sorta low but allways adding to it... any help is greatly appreciated.

welcome! what is your plan for HVAC in these rooms? you'll need a lot more than just a single pipe. if the room next to the mostly detailed room is your control room - the angles are wrong.
the hvac in the room as it stands now is for living room and upstairs bedroom. i planed on removing the duct work and replacing the metal with insulated round ducting and silencer boxes going through soffits. Yes the room in question was going to be my control room. Which angles are wrong? was just a quick sketch to see if anyone thought my rooms would be too small.
i think its pretty tight however you do it.
That works, i was originally thinking of going that way but was unshure if the ducts above would be a weak point. i plan on making boxes of 3/4 birch with double 5/8 drywall on bottom just like the mass in rest of ceiling. Would this be fine or is there another approach? Tried searching for it but could not find info on air returns. Thanks again
plywood and drywall on a soffit frame plus a baffle box on the penetrations will do it.
i have an area in rafter by the fron and back that is about 7" and gap is about 3" to try to get mass in there should i try to do it or since it would be outside the walls of the room not to worry about it? and just fill with insulation. the first half before the concrete does have mass in it just when i get to concrete. added a pic thanks again
one more question is the dark triangle in the CR a bass trap or a wall?
the dark spot is a trap which in reality would be part of the overall back wall treatments. on the 3" gap - if the ceiling mass and wall mass will join and seal, then it shouldn't be an issue. if it would be an opening in the isolation - then you need to cover it. so if you're using the concrete wall directly you'd extend out to it and seal. if you're looking to add another wall inside the concrete then the usual nesting of layers and sealing would apply.
Finally finished my ceiling bins. Now i have a question as i start building my walls. The booth i will be building i want to be inside out. now do you put insulation between the concrete and the 2 layer's of drywall or leave it empty? and on the other side where the control room is i would repete the wall to keep it 2 leaf?

one more how much of an air gap do you leave between walls usually?
Put insulation in, for sure. If not, it will cost you a lot of isolation (between 5 and 15 dB, roughly). So how do you hang the insulation in the cavity if there are no studs to attach it to?

How much isolation do you need) (in decibels). And what is the lowest frequency you need to isolate? Those two help determine the size of the air gap, and also the amount of mass to put on each leaf. But don't ever go with less than 4" of air gap: it compromises isolation and pushes up the MSM resonance to frequencies where you do not it to be! - Stuart -how much of an air gap do you leave between walls usually?
