The initial boom is less than a second but it's like standing right next to the leafblower (not across the street) and is accompanied a lasting thundering-noise which is also extremely loud.

Yeah, and it's entirely unexpected. Just, out of the blue, boom. A deep shaking sound wave blasts you.

The people defending this don't seem to know what a sonic boom is like. Even if you diffuse it some, it's a ridiculous force. These are huge jets. This is going to be a new ambient disruption that makes every single day worse, filling the world with din, every day, for possibly billions of people.

This is such a downgrade to the world. While the ultra-rich Tiphares style look down on the world.
