Recent advancements in acoustic technology present a novel method for delivering audio via inaudible ultrasonic beams that form audible sound pockets in space. Reported on March 17, this method utilized two ultrasound emitters crafted with 3D-printed metamaterials, allowing the beams to bend around obstacles and intersect to create designated zones of sound. This technology has applications ranging from personal audio experiences in home theaters to enabling communication without devices, addressing the growing demand in a world filled with podcasts and on-demand audio.
The new technology creates pockets of sound using ultrasonic beams, allowing audio delivery without isolating listeners from their environment.
This breakthrough improves upon parametric ultrasound technology, making it possible to create audible sound in specific locations without requiring traditional audio devices.
