I've found to really knock out the ringing in a 511b, the 3 welds in the sectoral vanes have to be cut. The amount of external damping then required to eliminate self resonance is dramatically reduced. I applied a few coats of rubberized automotive under-coating on the external surfaces and filled in the cut welds with automotive seam sealer before repainting the horn. Looks like a factory new horn but no ringing. Rope caulk is very effective at damping too but I hate the look on an exposed horn.
