    Hi-

    I am building a vocal booth in my apartment, on top of an existing wood finished floor that is not insulated and rather old.

    I originally built a plywwood deck on top of 2X4 joists decoupled with u boats, but after reading Rod Gervais' book decided to dismantle the entire floor and just double up on the plywood.

    As of now, I have a 1/2" rubber flooring underlayment directly on top of the existing wood floor. Someone recommended inserting a layer of 1" or 2" 703 in between the rubber and the 2 layers of plywood? Will this design work structurally? I know the 703 is rigid but can it support the weight on top and still maintain a level finished floor on top?

    If not, can someone suggest an appropriate design for this floor?

    If you are building a booth the size and like I would build the booth...no...the 703 will compress.

    But as a decoupling mechanism. ..yes it is a common suggestion...typically for a drum riser or vocal island or what have you.
