110dB 20km from the origin? That is a serious WTF right there if that number is accurate. If my quick estimate is correct that would mean that the sonic boom is deadly to anything within a few 100m around the booster. Even 110dB is skirting the border to permanent hearing damage from a single exposure.

Both the Saturn V and the SLS produced over 200dB. Considering that the scale is logarithmic the sound must be quite literally staggering.

Here's some noise data from Starship launches. This says that it emits over twice the acoustic energy of SLS at launch:

The launch (engines etc) are MUCH louder still.
