Despite SLS producing more than half of Starship’s overall thrust at liftoff, Starship is substantially louder than SLS. More specifically, one Starship launch is equivalent to that of four to six SLS launches regarding noise production.
- I'm surprised its so much louder than SLS. Usually SRBs are louder than liquid-fueled engines. I guess Starship is just bigger.

"Car alarms were set off at two data collection stations located 10.1 km and 16.6 km from the launch site..."
"...showed that Super Heavy produces a sonic boom that results in noise levels of around 110 dB when standing 20 km from the booster."
Wow that's loud
