[QUOTE="Tzs503gp, post: 1167583, member: 19443"] While the intent is good, I think the approach(es) suggested here are counterproductive. You have a resonant floor on which stands whatever. You want to isolate that whatever from the physical movement of the floor. The only way you can achieve that is with a substance which will compress and decompress in anti phase of the floor resonance. Finding such a substance will require knowing the ( most offensive) resonant frequency of the floor, the displacement of the floor under whatever during resonance, the mass of the whatever, and then find a material (of the corresponding thickness) which stores and releases energy at exactly the rate determined by the mathematics ( which I do not have at hand), for the displacement of the floor. ANYTHING else will result in a scenario where the whatever will cyclically move in phase and out of phase with the floor at the resonant frequency of the floor. If, as suggested, the resonance is offensive to the sound of the room, the solution is to address the problem- the floor resonance. Full floor carpet would be a good starting point. [/QUOTE]
