I'm looking to dampen the noise and vibration from dropping heavy weights on the floor (200lbs from overhead, 500 lbs from waist height, multiple 100 - 250 lbs people jumping onto boxes, etc). I've got to build on top of what I believe is 2" of concrete poured on top of a steel composite structure.
The standard rubber matting on top of whatever floor exists in combination with using bumper plates for weight will very likely not be enough. In consulting with similar applications, we were directed to putting this type of floor down as a base:

It appears to be a standard gymnasium type floor, but it's my guess that this is very expensive to both purchase and have installed (I believe it requires a specialist to design and install the right mix of rubber discs in the proper configuration).
Has anyone every had experience and success with putting down this kind of floor for this purpose? What about success with less expensive alternatives?
I'm thinking a well-built subfloor with insulating material underneath thick rubber might be enough...
