MIT Invented Laser That Can Send Sounds

Researchers from Massachusetts Institute of Technology invented new technology that can beam sounds to a specific person using a laser. It works by using eye-safe laser which heat the water molecules in the air, creating a local sound.

Currently, the tech can send sounds up to 60 decibels with a distance of roughly 2.5 meters. But the team are working to make measurements longer, 100 to 500 meters.
