I'm looking at a studio in a building that will contain multiple studios. The plans have been made and the walls have been framed but not yet built.

I will try to explain the plan:
There will be four individual studio units, side by side, each with it's own control room and tracking room. Each unit wiil have double walls on the sides and in between the control room and tracking rooms with 3 layers of drywall. Each unit will also have a 5' wide storage unit between it and the other units for added sparation. The rear wall of the tracking room in each unit is NOT going to have a double wall and is shared by each studio unit. The other side of that wall is a hallway and each single-walled rear wall has an entrance to that hallway.

I am concerned about sound travelling between studios through this rear wall and am wondering if this is going to be a problem that is better solved at this stage of construction. Is this a valid concern?

I can post an illustration if my explanation of the layout is difficult to understand. Thanks

I believe your concern is valid, because one weak link compromises the entire chain. I'm not much of an isolation expert, so maybe Rod or others will chime in with better advice.

If you have already framed the walls in,the design must already be in place.Can you give us a diagram,and your budget?
A "room within a room"design is what is required,ie..floating floors,walls and ceilings.If you have corridors between the studios to access them,and act as a sound lock this will add further isolation.
If the studios share a common ceiling,and floor,then you will have some leakage.You would have to consider how you schedule your sessions,ie..don't have a loud rock drummer next to and acoustic guitar session.Low frequencies will travel through the common stucture.

Thanks for your responses.

I'm not sure about the budget because I'm not building the studio; only renting it. It does seem at this point that the person building it is open to suggestions about how to lessen the leakage from one room to another.

I'm trying to post a diagram but am not doing too well with it.

Oh and I forgot to mention that the blue walls in my diagram represent the common walls I'm concerned about. Thanks

There will be leakage from the adjacent control rooms,as they share a common wall.At least the tracking rooms don't,and that is the most critical.If you are hearing alot of bass comming from someone mixing next door,they are probably mixing too loud.You could have the builder/owner put in floating floors and suspended ceilings,but if your walls are coupled with a common floor and ceiling they will become transmission points.
As Ethan stated,"One weak link compromises the entire chain",and there seems to be more than one week link,in this design.It could never be an S.P.A.R.S. certified room,with 60dB of isolation,but most of are rooms don't meet that standard.I really depends on what you require for a noise floor.
What type of mosic are you going to be recording?What is the owners budget?
