A few pointers
Your canvas setup is probably the cheapest/best.temporary solution. 2"x4"x92"s are 3 dollars each,4'x8'x1/2"gypsum board is 12.95$ each.Acoustic insulation Roxul is about 30$ a bag of 10 butts.Then you should run 2"x6" for base and headers so you can stugger the 2"x4" on 16" on center.Tha way you create acousticaly dead wall with the insulation installed in the cavities of course.Don't forget a box of drywall screws and nails to put the studs together.I agree about the floating wall.Just cut short and install a layer of thick foam band(pink brand insulation sells rolls of that ) at the header between it and the beam.Make sure to drill pilot holes at the header larger than the screws diameter to allow for movement up/down direction.Add the cost of taping(plaster) and prime/paint and baseboards for a finish look.Lastly how temporary is that for a wall?
Prices are in Canadian dollars at Home Depot but close enough to USD.
Best of luck
