Good way to dampen tonearm?

A small collar of dynamat extreme (a car damping material)
inproved my rega tonearm. In fact I used at a number of locations on my old turntable which tought me how substantial and corrupting is all the radiating and extranous energy going everywhere in a turntable.
Tuff job getting rid of it all...

Why are you even thinking of adding dampening material to the tonearm? Does it noticeably ring when you tap it? I've read good things about the wire upgrade, but I would otherwise leave the arm alone.

try to find an old Stereophile 'analog survival kit' tonearm damping wrap

"conservation of energy = Within some problem domain, the amount of energy remains constant and energy is neither created nor destroyed. Energy can be converted from one form to another (potential energy can be converted to kinetic energy) but the total energy within the domain remains fixed. "

all the energy from bearing chatter ,the spindle bearing friction, the stylus dragging through the grove etc has to go some where, my own intution (thats as good as it gets for me)suggest this is easily conducted throughout the turntable and into the tonearm etc, a further guess of mine is that some of the materials contemplated (foam for example)dont really get rid of it but are only to varing degrees conductors of this unwanted energy
