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?

@geoffkait It may have been a writer who was not writing for Audio during WWII, but who did write for them later. I used to be a subscriber to Audio and I believe it is in this magazine that I read the story.

Yes, his idea was describing sonar, but he did not name it as such at the time, it had no such name in the public domain.

As I recall the story, the US navy was already working on or using sonar, but the Audio writer did not know it. He just wrote an article and published it saying it would be a clever idea, which caused some branch of the US to interview him at length about how he came to his ideas.
BTW, I believe that during WWII a writer at Audio magazine suggested using sound waves to detect submarines, which was actually a highly classified secret at the time. 

Some one please fact check me. :)

It may not be acoustical. It could be microwave. Theoretically (and I’m out of my depth) frequency modulated microwaves could move the fluid in the head, causing acoustic like side effects.

Or it could be microwaves being used to excite a local acoustical device, kind of like the famous State Dept. Seal bug, but in reverse.
