Noise-canceling headphones are widespread nowadays, but scientists have found a way to take these devices to the next level — by creating headphones that can focus on one external sound source and block out all other noises.
The technology, called "Target Speech Hearing," uses artificial intelligence (AI) to let the wearer face a speaker nearby and — after a delay of a couple of seconds — lock onto their voice. This lets the user hear only that specific audio source, retaining the signal even if the speaker moves around or turns away.
