"I had an issue with vibration as I live across the street from railroad tracks. I built an isolation platform out of a heavy wooden butcher block board and isolation pods. It still had issues so I went to my local granite supplier. They gave me a piece of granite 1 1/4 inch thick from the scrap pile. It was too big for my cabinet so I had them cut it to 18" x 14" for me. They only charged me for the cutting($10.00) so I got very nice piece of counter top grade granite for $10.00. It solved my vibration problem and I haven't had any issue with ringing."
Ringing rocks are nothing new and their individuality from other rocks even from the same locality is well know if not well understood:
Search lithophones on youtube sometime.
I wonder if the Flintstones played the ringing rocks while dancing in the singing/whistling sands? Now that'd be cool gig!!
