How far off shore have the launch rigs to be to be noise acceptable? Phobos & Deimos.
A further question is where can you launch Super Heavy / Starship such that noise is not going to adversely affect whales / dolphins / porpoises / pick your favorite marine life-form.
In Scotland it will be when people on shore get upset.
Where do the noise limits come from, anyway? I mean, I suppose in regulatory terms from the FAA, but what are they based on (ie how is it determined what's acceptable vs not)?
There have been plenty of studies on different types of noises including music for intensity and duration versus hearing damage. There have been studies on noise at and around airports. There are noise abatement procedures on flights at specific airports to keep noise below certain limits. The FAA will have plenty of history to draw on for noise regulations.
There's also sonic booms on return and the vague possibility of a larger booster later.

Yes, but a fairly easy question to answer. The answer is, anywhere.There’s no fences in the ocean and marine mammals are known to move around quite a bit and to be surprisingly resilient to human noises. Also not too much acoustic energy moves through the air/sea surface interface, so it’s not a real problem the way underwater explosions or active military sonar may be.
There's too many splinter threads. This is just stupid now.
