Piezo elements are used in the reverse manner for the rest of the world. They are merely speakers, that produce a high pitched annoying noise, used for alarms and buzzers. The frequency you are referring to is the actual 'frequency pitch' they produce when used for such things. It makes no difference when using with edrums, as they just produce a voltage when struck. The larger the piezo, the more voltage it will produce. If you use, say 35mm piezo's, you may have to lessen the voltage using resistors, as the signal will be too hot.
