Somewhere between thick and opaque noise-blocking curtains and clear sound-reflecting glass windows there was a missing link, and this textile is it: lightweight and translucent, it sucks in sound without obscuring your view.
Specializing in Materials Science & Technology, the EMPA worked with textiles experts, acoustical engineers and computer modelers to weave disparate disciplines into a new compelling set of acoustically-altered patterns. Passive noise cancellation is of course a particularly tricky task in malleable and thin materials due to issues of density and directionality.
Mathematical projects and digital models led to real manufacturing and testing, resulting in something five times more soundproof than traditional hanging curtains (and significantly better than bare concrete or glazed surfaces) but still sufficiently fireproof and translucent to let in strands of daylight.
