I think I need to expand the design brief to include something disruptive to microphones as well.... maybe something loud in the >18kHz range? sure, it'll annoy the yoof but my ears are past annoyance in that range!
Go for it. Maybe some sort of a small, guided missile or something more powerful to destroy such devices. Knowing how things are though, there will be videos of incoming destruction taken by the targets.
