Maybe, but there’s no way to tell from this article.

I keep seeing these reports of how NASA and DARPA are coming up with techniques to “shape” shock waves and sonic boom, and how this is going to lead to a brave new world of overland supersonic flight. But I never see any quantification of the benefit of such techniques. The other thing that I never see is a discussion of the effect on wave drag, which is the other big factor that prevents economical supersonic flight.

As I’ve written before, there actually may be design solutions that can significantly reduce, and even approach elimination of both sonic boom and wave drag, but NASA and DARPA continue to refuse to consider them. Perhaps when this latest attempt doesn’t pan out, they’ll be willing to finally do so.

Here’s a Usenet discussion on the topic from a few years ago among yours truly, and several others.
