I am more familiar with resonance in an electrical domain more so than a mechanical one. How do they determine at what frequency to actuate the piezos in order

I am more familiar with resonance in an electrical domain more so than a mechanical one.
How do they determine at what frequency to actuate the piezos in order to match the resonant frequency of these plastic particles? Is it just 'guestimated' or is there a more systematic way?
- newfocogi 7y agoMy guess would be that they choose the frequency based on the speed of sound in the liquid such that the nodes in the standing wave occur at a designed location in the chamber where the separation occurs.
