Tuning dots, if they work like drum head dampers, reduce vibration and ring. Sort of like when you lightly touch a ringing wine glass. Depending on how softly or firmly you touch the glass, the ringing will be reduced or eliminated.
At least that's how I believe the tuning dots...or felt/rubber furniture protectors...would work.
