Sure. An immobile hunk of very dense stuff which
carries vibrational energy ( hardwood rim ) or one
which sucks it up like a mop ( chipboard ). As a
tuning fork applied to a hardwood rim will be heard as
soundboard resonance, so will vibrational energy which
has escaped from the board to the rim. Its ability to
re-enter the board at some other point is greatly
enhanced by a rock-solid rim, IMHO.
