Listen to music without headphones, but with ultrasound beams. A research group is trying to achieve this result, bringing a revolution in the field of technology. Listen to music without headphones, with the sound that seems to materialize in the air, but that only you and no one else hears.
It’s not science fiction, but such technology has already been developed, which creates sonic enclaves, or certain areas where ultrasound beams intersect, producing audio audible only at specific points in space.
The new technology combines these ultrasonic bands with 3D-printed materials that are able to shape audio waves.
Tests conducted so far have been successful in localizing sound to a specific listening area, showing promise for future applications. This technology could find use in many areas, from home entertainment, where each family member can have their own audio without disturbing others, to vehicles, where each passenger can have their own listening area.
