    I remember seeing this about 2 years ago, and I was extremely interested in the topic, but there was a discovery that there's an open ended ring that can cut 94% sound. An acoustic metamaterial, it sounds extremely useful for things like earbuds/IEM's, and Earplugs, but also in places like walls where people usually put sound-proofing foam in its place.

    Do you guys have any other ideas on what to use it for?
