00:00Researchers develop targeted audio technology that sends messages through a crowd to just

00:05one listener.

00:07Penn State's new targeted audio tech, called Audible Enclaves, uses ultrasound to deliver

00:13sound only to a single listener without headphones, creating private audio pockets in busy public

00:19spaces.

00:20This innovation could transform privacy, noise control, and accessibility everywhere.

00:29Sound waves naturally spread out, making precise audio control hard and limiting privacy with

00:34traditional speakers.

00:36Penn State's new targeted audio tech overcomes this by delivering sound exactly where needed,

00:43reducing unwanted spread.

00:48Penn State's targeted audio uses silent ultrasound beams at different frequencies that intersect

00:55to create audible sound only at precise points, allowing sound to be heard solely where intended.

01:04Penn State's acoustic metasurfaces bend ultrasound waves around obstacles like heads or furniture,

01:12enabling targeted sound to reach listeners off the direct line of sight, covering speech and

01:18music frequencies.

01:23Targeted audio tech enables personalized sound in museums, offices, vehicles, and public spaces,

01:30creating private zones for guides, conversations, and immersive experiences without disturbing others.

01:37It also helps reduce urban noise pollution and enhance entertainment venues.

01:46And audio tech faces challenges like sound distortion, high power use, limited range, and the need

01:52for real-time listener tracking.

01:55But ongoing innovations aim to deliver clearer, dynamic, and immersive sound experiences.
