A vibrating curtain of silk can stifle noise pollution

Inspired by headphone technology, silk sewn with a vibrating fiber acts as a lightweight sound barrier

A slim sheet of silk could smother noise coming from the other side of a large room, reports Andrew Chapman in Scientific American. DMSE’s Yoel Fink and a multidisciplinary team of researchers have expanded on technology found in noise-canceling headphones to tackle noise pollution, which contributes to stress, sleep problems, and even disease. A piezoelectric fiber stitched into the silk emits sound waves that can cancel out sounds as loud as 65 decibels, roughly the volume of a human conversation. “That was striking to me because it’s a piece of silk [with] the thickness of a hair,” Fink says.
