Bob DeRosaRe: TUBE RINGS ?
Haven't you ever had a microphonic tube that would quiet down when you pressed your finger against it?  
 
What you are doing is changing the resonant frequency of the tube (through dampening) to a range that is outside the range of the frequency that is exciting it.  
 
This is what a tube ring does.
