Anyone else will just hear the tapping, and think it annoying. I think it's somewhat an audible illusion, since you're already playing the song in your head, so you expect the taps to correspond with the high and low notes of the song you are "playing." Anyone else won't hear it.
I remember hearing on the radio about a study where they actually tested that. The...tapee? only recognized the song 1 out of ...[some number between 20 and 100 that I do not remember] times.
Well, with most non-melodic percussion sounds, the tone is a set of atypical harmonics; when you hear a pitch that sounds like a certain note from hitting a table, you probably have heard it, but the reason most other people don't is that there are so many other harmonics going on that they can't distinguish it.
That would be something to try. Seed both the tapper and the listener with an initial pitch (like through a pitch pipe), and then see how successful they are.
