Researchers at Penn State invented hypertargetable audio that doesn’t require any equipment to be worn by the receiver https://futurism.com/sound-audible-enclaves

Is this like directional audio?

You could say it’s like telepathic communication, just like in anime 😅

I hope it won’t be misused in the future; I see a lot of potential.
But I hope future technology moves in a positive direction.

Yes!! It’s hyper targetable directional sound, same underlying technology!!!
