Looks to me like the thick block actually rings like crazy, but only at frequencies above the range of human hearing.

I can ring my trombone mouthpiece. It looks to be about the same size as those metal blocks, but that sound is definitely audible, within human hearing. I would guess somewhere between 8000-12000 Hz.

Chris, have you tried ringing the blocks while hanging them from a string?
