Scientists Create ‘Pockets’ of Music from Inaudible Ultrasound Waves
SMRTR summary
A new acoustic technology creates "audible enclaves" by crossing inaudible ultrasonic beams, allowing sound to be heard in specific spots without headphones or speakers. Researchers demonstrated this by playing music for a dummy head using beams bent around obstacles, potentially leading to applications in cars and home theaters.
