Sensing Device Separates Simultaneous Sounds
A new technology developed at Duke University uses metamaterials and compressive sensing to determine the direction of a sound and extract it from the surrounding background noise. Once miniaturized, the device could have applications in hearing aids, cochlear implants, and ultrasound medical sensors.
