Probably Not Good

Article: This is incredible but something tells me this may be used in other ways than good by the industrial military complex. What are your thoughts?

Imagine standing in a crowded room and hearing a message meant only for you without headphones, without speakers, and without anyone else noticing. That's exactly what scientists at Penn State University have achieved with their new innovation: audible enclaves. Using the power of ultrasound, this technology directs sound to a precise point in space. By intersecting two ultrasonic beams, invisible and inaudible to the human ear, researchers create a pocket of audible sound that exists only at the exact point where the beams meet. Step outside of that point, and the sound disappears. This means you can hear music, instructions, or even conversations tailored just for you without disturbing anyone nearby. The possibilities are endless: museums with personalized tours, public announcements only heard by the intended person, or even quiet zones in shared offices where private audio remains truly private. It's a leap forward in the way we think about sound not as something broadcast to all, but as something sculpted in space, delivered precisely and personally.

My thoughts: I suppose this could be used by the CIA (or some other scumbag organization) to send a message to one person so they seem INSANE when they tell others they heard it?
