I have placed 15kg worth of dumbbell weight plates under each bed post in hope this might reduce meditation of sound vibrations due to neighbors walking and running and doing whatever else to cause them. It works a bit but not as much as I'd like.

You can get Sorbothane pads to go under your bed - Sorbothane is a material designed for vibration reduction.

You want something damping for that. Some sort of hard rubber would be ideal.

I need to understand more about the physics. so far the most convincing argument goes for mass.
