But is the wood not sitting on concrete, through which the vibrations from elsewhere in the building are conducted? If so I suppose the wood and the concrete will make differential contributions, and you might want to couple more proximally to one but not the other.
My point about the resonance is that it will accumulate only where the signal is stationary: the fres is always less than the single impulse, no? So as long as you are dissipating energy you cannot get an enhancement of the vibration you are putting in, only a dispersion in its spectrum.
For sand to work here in friction does it not have to be load bearing itself: i.e. inside a steel cage that propagates the vibration through the walls there will not be much friction, no? What you want is a sandcastle.....
