New Computer Chip Poised to Combat Cell Phone Background Noise
UNLIKE SounderCover, an "alibi application" that allows a user to add background sounds to phone calls so that one can pretend to be somewhere else, scientists at the University of Toronto are working on a (serious) way of minimizing background noise, according to Scientific American.
"Their novel dual microphone system--which highlights a speaker's voice and removes extraneous sounds--could be miniaturized within two years, they say, making it less noisy to reach out and touch someone.
“In typical environments there is background noise and reverberations that make it hard to carry on a cell phone conversation,” Aarabi says. “This system employs two microphones that, just like the two human ears, focus on the speaker's voice and filter out other noises.”
