Not sure how this does anything to alter the laws of physics. But I guess it's a step in the right direction.

The title of the article is misleading, there will still be booms:

> Several U.S. companies are working on a new generation of luxurious supersonic passenger aircraft with much quieter sonic booms and improved fuel efficiency

They’re no longer sonic booms under the appropriate conditions. They still make some noise, as does, for example, high speed rail.

		They are in fact the same. 108dB loud.

I lived in the area where boom did their flight tests and the local news would announce days when they were testing. FWIW, I think they used scaled down aircraft so production aircraft may vary, but the boom was more of a thump. It comes on quick though, so some potential for startling, not on account of volume so much as sonic attack.
