Digital Trends (Aug. 31) -- Looking for a less bulky, intrusive solution to the problem of disruptive noise, the U. of I.’s Coordinated Science Laboratory is developing a wireless network that can act more rapidly than sound travels. “Because wireless signals travel 1 million times faster than sound, our ear device gets to know the noise samples much earlier before they actually arrive at our ears,” says Sheng Shen, a researcher on the project.
