Along the way, the team realized their material could also be used to filter out sounds.

They took the latter idea and ran with it.

Thespecially crafted fabric, made out of piezoelectric fiber, is barely thicker than a human hair.

This method is useful in small spaces but isn’t effective at room scale.

To tackle this challenge, they needed a different approach.

In the “still” mode, sound transmission fell by 75 percent.

While promising, there’s still a lot more work needed before even considering a commercial rollout.

They also need to figure out the best way to market it commercially.
