I found yesterday that when I was pushing, most of the time the bracelets would just hit each other, with a sort of light jingle, but occasionally one would hit the pushrim, with a very loud clang. So I moderated my pushing, much the way you might change the way you walk when wearing certain kind of shoes. I gave myself points for not making the clanging sound - that was an interesting bracelet side effect.
Today I'm wearing a cuff made of some sort of plastic and it makes no noise.
