RE: Looking for experience in damping material

Posted by pictureguy on August 22, 2015 at 01:23:12:
It is an ENGINEERED solution but follow along.
Lets say you have 2 'things' each of which ring like a bell when tapped or struck.
You'd say to 'damp the heck out of it' and the vibrations will 'go away'.

Well, another approach exists.

IF the frequencies of resonance are arranged JUST SO, the 2 vibrating pieces will actually cancel one another out and produce a fairly inert structure.

My Long Gone Dual 1219 TT had a 2 piece platter. EACH piece individually resonanted when struck. Bolt 'em together? Very inert. The resonant frequency was dropped to a VERY low value and at a low amplitude, given input energy limits. Worked well.
