- Are tubular wind chimes (open at both ends) coupling to the air primarily the result of bending vibration, vibratory distortion of the circular section, or something else?
I recently read a site dealing with tubular wind chimes. The author give some references that seemed to indicate that the sound we hear is the result of beam bending vibrations after the tube is struck. I'm not so sure about that. It is certainly true that striking the side of an open cylinder will induce many modes of vibration. Does anyone have any experimental evidence as to what modes of vibration we hear?
