Cool tech.  But double edged like most - "drones could have their turbines muted with such rings"

This is basically a lot like a Helmholtz resonator which reflects a specific frequency back at 1/2 phase to cancel acoustic vibration. Only works for continuously generated sound, and a particular frequency.
