Roadside pillars on an origami-inspired folding base could block traffic noise without restricting a driver’s view. That’s the hope for a new kind of “sonic barrier” proposed by Manoj Thota and ...

Illustrations of different folding configurations of origami sonic barrier and their corresponding cross section views. The pink polygons in cross section views identify different lattice patterns and ...

WASHINGTON, D.C., October 17, 2017 -- Managing traffic noise pollution has vexed researchers in large part because of the broad range of frequencies we encounter on the road. Currently, only heavy, ...

Researchers have brought a new method into the sound-dampening fold, demonstrating an origami lattice prototype that can potentially reduce acoustic noise on roadways. The technique allows researchers ...
