One night, my three roommates and I also had been spread across our typical area whenever one of our buddies FaceTimed in. I desired to listen to exactly just how he ended up being supporting, and my roomie place him on speakerphoneвЂ”but, as their voice wobbled through, its muddiness irked me personally.

To learn, we arranged a FaceTime call with Chris Kyriakakis, an electrical- and computer-engineering teacher in the University of Southern Ca and a chief sound scientist for Syng, a loudspeaker business.

A person is the length between my mouth plus the microphone. From him, his brain would focus on my voice and filter out any background noise if we met up in person, he said, and I sat six feet away.
