How to isolate turntable from footstep shake or vibration

Even while the Oracle turnable that I use has a built-in springs suspension by design there is a low or even sub-low frequency boom every time someone walks in a room. This becomes really bad with the subwoofer’s volume set high as the low frequency footsteps make straight to subwoofer where they are amplified shaking everything around. It seems the cartridge is picking up the footsteps very efficiently as even a lightest foot down becomes audioable. What can be done to attempt to isolate the turntable from the low frequency vibrations? Interesting, that the lower the volume of the subwoofer, the less the footstep shake is evident and with the subwoofer turned off it is a barely a problem at all.

A pair of heavy duty shelf brackets I found at a local hardware store, attached to a couple of studs with four lag bolts and a shelf made from a few pieces of pre-finished bamboo flooring did wonders for my Linn LP 12. An outside wall is best for this implementation. This proved to be a splendid, economical solution.

There is no need to spend silly money on various other fix-it schemes. The brackets and lag bolts cost about $15.00. I already had the bamboo. A small piece of 3/8" or 1/2" plywood likely would work just as well.

But, of course YMMV, to use the cliche.’
