Reply to comment by marimbawarrior in ‘We found the Artemis-I noise level at 5 km had a crackling quality about 40 million times greater than a bowl of Rice Krispies.’ — Maximum noise measured during Artemis-I launch on 16 Nov. 2022 was higher than predicted by marketrent

No bone to pick with most of what you wrote... but

> around the rocket

1.5 kilometers from the rocket.

IMMEDIATELY around the rocket (which is what I'd mean if I said simply "around the rocket") would be a different story. Obvs.

True! Inverse square law can help us out here.

Just punched the numbers in, 26 dB louder if you were located 80 meters away from the rocket, or roughly 162 dB. So yeah, 136 dB from 1.6 km would make total sense.
