Scientists Build System That Uses A Laser To Beam Sound Into Your Ear

Hearing someone across a crowded room can be close to impossible thanks to the way sound waves spread, but what if we could project audio with the same precision that we can project light?

Researchers from MIT have developed a system capable of doing just that, creating a targeted audio stream that can be fired at a person’s ears in much the same way that a laser pointer fires a beam of light. It’s accurate, safe and can transmit music and even speech to a target without being heard by others.

“Our system can be used from some distance away to beam information directly to someone’s ear,” Charles M. Wynn of MIT’s Lincoln Laboratory said in a statement. “It is the first system that uses lasers that are fully safe for the eyes and skin to localize an audible signal to a particular person in any setting.”
