Researchers at Penn State University have developed
"audible enclave" technology that uses intersecting ultrasound beams to deliver sound to a specific individual without the need for headphones.
These ultrasound waves are inaudible during transmission and only become audible at the point where they intersect, allowing the intended recipient to hear the sound while others nearby do not. The technology can also bend sound waves around obstacles to reach the target listener.
Potential applications include personalized audio in public spaces like museums and libraries, as well as in vehicles where passengers could listen to different audio streams without interference.
