On: World’s smallest, best acoustic amplifier emerges ...

[amelius]

Is it related to phonons then?

https://en.m.wikipedia.org/wiki/Phonon

> Phonons can be thought of as quantized sound waves, similar to photons as quantized light waves.

This technology is entirely analog. It has nothing to do with quanta. It simply converts electromagnetic signals of a certain band, into electricity, through an acoustic coupling, and amplifies the signal too, in an all-in-one manner.

But the quanta can generate shot-noise, just like the quantized electrons can in an electronic design?
