What can I put under the feet of my bed to dampen/eliminate low-frequency vibrations?
My partner and I are bothered by vibrations that are coming through our apartment building, we believe caused by the compressors for the cooling units for cell-phone equipment mounted on the building.
We have an ongoing issue with the management company and the (multiple) operators of the equipment, to try to resolve the problem. They've already made some changes that have lowered the audible humming sound (which was a big part of the problem).
But at times the machinery produces a significant enough vibration that you can feel it quite strongly, while lying in bed. It is an unpleasant sensation, and keeps us from sleeping (we've tried to get used to it. No dice.)
I don't have confidence the vibration will be totally mitigated by the operator of the equipment (we're trying), and in the meantime we're looking for a solution that will allow us to sleep better.
Do the acoustic-physics geniuses & sound engineers among you have any suggestions for materials we could put under the bed, or under the four legs of the bed, which would dampen these vibrations? (This is a wooden frame bed, with a mattress that sits on slats, no box spring.) Or am I just fantasizing about such a remedy? Incidentally, I've already read this thread
. There was the suggestion of Sorbothane
, but I don't know how practical that is.
