Audio as a weapon


I would like to deviate a bit from the normal audio equipment conversation and delve into the phenomenon of the recent audio "weapon" that appears to have been deployed in Cuba upon State Department employees and now, it appears, in China. I know that very low frequency can be dreadful to listen to but anyone out there have any ideas with regard to how audio could be used as a weapon? It is not my intention to draw speculation of a political nature, I am only interested in the technical aspect of audio as a "weapon". Anyone have any thoughts?

Making people deaf is not something that shows, like a knife in the gut, or a blown off leg.

So they can use sonic attacks as a deterrent and punishment of a group, and get away with the non existent pr issues.

Sonic attacks seemingly roll around in the same realm that the audiophile argument is in.

Since people can’t actually see it our touch it, then in their mind it probably did not happen, if they have no "real" data on the source point..

(define real -please and thank you. Good luck with that. A place where science trips over its own psychological stance... and has to deal with being ensconced in a subjective human reality -as all human reality is)

Even if it is all too real. Like the audiophile conundrum, it is a conundrum not because it is false ....but that the given mind has to weigh in on the subject, with no hard solid object that they can grab and sense directly. A case where objectivity taken to an illiterate extreme delivers a form of circular insanity to the position holder.
