The proposed limit is around the level of standing right next to a leaf blower.
That's fine. The occasional boom, assuming business success this time, will last a few seconds. Leaf blowers last for hours in some neighborhoods. It's not the hearing damage, it's the psychological stress.

As I understand it the noise pollution stuff is due to really old tech. The new stuff should be much better performing to basically eliminate the sonic boom and the regulatory changes are reflecting that. On a site like HN this kind of progress should be praised not denigrated as antisocial.

Too bad because HN has been my “home” on the internet for 15 years.

My parents immigrated to the US in the 80s. They didn't steal anyone's land. Can I complain about rich people wasting fuel, polluting the air, and creating peace-shattering sounds? And about the stolen land, what should we do about it? Never complain about anything? Have no laws? Give all of your stolen land back, make all the reparations you owe people, and then go back to lecturing people online.
0.11 pound per square foot is what is being proposed. That's 108 decibels. Which is between standing next to a lawn mower and standing next to a car horn. I don't see how anyone will tolerate that in practice. https://www.omnicalculator.com/physics/db
Oh! Really?

1. Better, real-time atmospheric data that allows use of boom-refraction flight profiles to prevent the boom reaching the ground. This is a trick that Concorde sometimes used when conditions were right, but only works up to about Mach 1.2. This is what Boom used for quieter flights.
2. Crazy 1950s-style airframe shaping with the X-59 that reduces boom but is impractical for an actual commercial transport. This is intended to establish a baseline for tolerable routine boom intensity, but we don't yet know how to make a commercial airframe with the same quietness.
Nothing is really new.
If you really want to make an impact on the noise floor, ban gasoline leaf blowers.
These things are indeed "The Devil's Hairdryer"

When people talk about this stuff, it isn't about apportioning blame.
I'm not big on the stolen land thing because it's turtles all the way down, but this idea of divvying up blame makes no sense. We are all citizens.
