Supersonic flight doesn't have to be as noisy as the Concorde was. Remember, Concorde was designed in the mid 1960s (over 50 years ago) with minimal use of computer modeling. We've had decades of advances in computer modeling and processing power so it's now possible to design planes with much quieter sonic booms. On the order of 100x to 1000x quieter.
Here's one plane being developed by Lockheed Martin, "designed to create a sonic boom only 1% as strong as that generated by the Concorde." Though, this plane is smaller than the Concorde so it's boom should naturally be smaller, however the idea still applies to other supersonic planes.

Lockheed Martin claims their design only generates 60 A-weighted decibels of noise. This is compared to the Concorde’s sound at cruising altitude of about 90 A-weighted decibels. 60 decibels would put it at about the sound of a normal conversation. That would make it quiet and non-intrusive enough for overland flights.
