Reminds me of a "design concept" for a little Nest-shaped box to stick on your window and magically cancel out all street noise. I'm pretty sure this is actually impossible, and is the equivalent of drawing a pegasus and saying "I have this great concept for a novel form of transportation!" i.e. more or less not worth anyone's time, since it's fantasy.

Possible in a controlled lab environment if you can destructively interfere the sound, but it's gonna depend on the sounds as well as knowing the location of the listener

Here it is, for reference. I could imagine it possible in the lab, and I'm not an audio engineer but the whole thing is completely implausible.

And sites like Gizmodo don't bring any critical thinking and just repeat the claims verbatim.
