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.

It’s not accurate to convert .1 psf to dB because it’s an impulsive shape, not a continuous tone. And human loudness perception depends on how smooth (low frequency) the shape is

		> It’s not accurate to convert .1 psf to dB because it’s an impulsive shape, not a continuous tone. And human loudness perception depends on how smooth (low frequency) the shape is Sorry can you explain more? It's just the definition of dB (?) And it's less impulsive than you imagine, go to youtube to listen to the sonic boom + continuous roar. The FAA has no criteria about the "texture" of the sound and there is no reason to believe the allowed planes will differ substantially in this respect compared to every other supersonic aircraft in the past.

Because it's not continuous sound in one spot like a leaf blower is.

There is a substantial noise beyond the initial boom which is very loud even relative to the main boom. But even just a half second of a car horn going off right next to you every so often is intolerable.

People finding a way to tolerate what was previously considered intolerable is pretty much the story of civilization.

		I'd argue that civilization is the story of people finding ways to overcome what they previously had to tolerate.
