Your ears may be used for more than just hearing sounds. Did you know that the top part of your ear does not change shape as you get older? And that someday it may be used to identify you? According to Technology Review, researchers at the School of Electronics and Computer Science of the University of Southampton are working on it.
Squareheard Technology has a new microphone system, AudioScope, that allows broadcasters to zoom in on sounds as well as sights, to pick out a single conversation. The device is made up of around 300 microphones used in conjunction with a wide-angle camera that can zoom in to any position. The AudioScope software then calculates the time it would take for sound emanating from that point to reach each microphone, and digitally corrects each audio feed to synchronize them with that spot.
