Well, I wish I could see it at CES (as they state it will be) to confirm or disprove your assertions.

Can't you just have an extra noise cancelling drone that creates an equivalent cancellation sound wave?

Even if it is "fiction," it fits into the "science fiction" category and I love it as such. The rendition is such a beautiful idea that I'm happy they created the web page to showcase the idea.
