Uh, no...you don't. Sound will transmit over the common top and floor
plates.

No ****, sherlock... as it will between the decoupled wall surfaces,
as well as through the floor. But this method is very effective on
reducing the amount of sound transmitted through the wall. No one is
talking about a truly soundproofed room; that's why I called it a
"soundproof" wall (notice the "quotes"). Everyone caught that except
for you.
