> 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.

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.

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

Up next is boom's line of of landscape blowers

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.

It's reflective of the gradual dawning that while technology is amazing and exciting and can help people, under current systems it's more likely to be used to benefit the thousand or so richest people in the world and fuck everyone else over. Could we make supersonic jets more quiet and less disruptive? Yeah, probably. But why would a single cent be spent on that? The people flying in them don't give a single shit. They would only get quieter as a side effect of an improvement that somehow increases return.

The 'new stuff' is split into two categories:

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.

I'm just very very skeptical I'm going to be able to sit inside or sit on the porch and not know it's going overhead. Which I can do with most planes today. I've only heard a couple supersonic booms in my life & they are incredible & ridiculously disruptive events, in a whole body sort of way that is without compare, even if I'm deep inside a heavy massive brick building.

This definitely feels like a Time Machine Morlock/Eloi, Battle Angle Alita Tiphares, Neuromancer Freeside situation, of the extreme rich untouchably far far overhead dumping endless waste noise pollution and din down onto the earth.

This administration in particular seems to absolutely not give a rat about anyone but the ultra-rich or the brownshirted anti-social and I have no confidence they are doing this based on any form of reasoned or sensible approach. This is an administration whose modus operandi is to roll coal, drill everything, cancel every green energy project (by spending billions if they have to buy out the already underway installations), go to war against vaccines/mRNA, etc etc. There's no baseline upon which to expect reasonable or smart or safe.

There is no profit, which is why their is no service. The average profit margin is 4% on flying.

At this point, airlines make most of their actual profit from credit cards.

I forget who said it, but "airlines are banks that happen to fly planes" is true, at least profit wise.

Good news, airlines already barely profit:

Put that on a T-shirt!

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.

Nimbyism is generally against a public good (low income housing, powerlines, etc)but there is nothing public or good about this.

Calling this nimbyism is billionaire psyop lol

Where is this claim?
