Mika,
I am the acoustical designer for the new Airshow faiclity, and I designed the floors.
I am not particularly worried about the floors. The Live room, which we expect to be the loudest space by far, has a 2" puck based floating isolation floor, with a built-up multilayer floor on top of the iso pucks. The multi layer floor includes a high mass panel and a honey-comb isolation panel.
The mastering room is sitting on an 5/8" honey-comb with a built up multilayer floor.
In terms of isolation, I am much more concerned about walls and doors than these floors.
You are correct that a concrete slab would provide more isolation, but several factors made building a slab problematic - 1. we did not want to lose any height for these rooms. To be effective an iso slab has to be at least 7" thick (including iso pucks and sub floor). 2. Cost. 3. Airshow does NOT own the building and many landlords find pouring slabs a problem (many want large deposits to ensure they can pay to remove them if you leave). 4. I did not think more isolation was required.
So there you go! I am traveling to the site today and I am exciting to see the facility this close to completion!

I had alot of problems with this kind of floating floors.
In my build i had to get out this type of floating floor, and will now go with thick concrete over sylomer.
Who makes the disign for this floor?
cheers
