Several things happen.  Some of the very low-frequency components are
carried right down the piano legs to the floor, and the floor acts as a
secondary low-frequency soundboard.  It's all in the coupling of the piano
to the floor.  Those hard brass casters do it.  Solid blocks will do it
too.  A stage truck will not do it.  In fact, it will isolate the
vibrations of the piano's structure from the floor.
I have often wondered if there is some carry over. The piano in our concert 
hall sits not only on a truck, but on a wood floor, which is suspended. (There 
is a pit under the stage floor.) One of our professors claims the piano has a 
crack in the soundboard, because he can hear a low grumble when the piano is 
played. I can't hear it. 

What about the touch feel of piano sitting on a truck, on a suspended floor?  
Does that effect a feeling of touch? Anyone with a comment on that?
