... for instance, if the rods were built with the inclusion of small chambers containing a volume of air whose fundamental harmonic was the same as that of the rod-- when struck, the rod would transfer vibration to the enclosed air as well as directly to the atmosphere, resulting in a louder tone. A hard connection between rods and frame would also accomplish this result somewhat; the vibrations of each seperate rod would be commuted to the others, resulting in more vibrating surface area (and hence, more volume). The transmission of the chime's sound without the abovementioned alterations is quite simple; each rod releases longitudinal waves ...
