Starship super heavy acoustics: Far-field noise measurements during launch and the first-ever booster catch
Far-field (9.7–35.5 km) noise measurements were made during the fifth flight test of SpaceX's Starship Super Heavy, which included the first-ever booster catch.

After your other fans are done watching, I know a couple of articles about Starship's acoustics that they can read... 😁
Here's the latest: doi.org/10.1121/10.0...
(The thumbnail shows sound speed in different directions - the much larger differences during Flight 6 led to more variability.)

Starship Super Heavy acoustics: Comparing launch noise from Flights 5 and 6
This Letter analyzes launch noise from Starship Super Heavy's Flights 5 and 6. While Flight-5 data covered 9.7–35.5 km, the stations during Flight 6 spanned 1.0

We have another paper coming out in the next week or two that builds on the first study!

Thanks for the post! One point of clarification. 10x the acoustic energy doesn't mean 10x loudness. Loudness, unfortunately, is a complicated measure that we didn't get into. But for someone keeping track of launch cadence and impact, it does look like at least 10 Falcon 9s launching, energy-wise.

I have an excellent track record for losing ASA elections. I think I'm 0/5 now! It's all good. I'm happy working with POMA and other technical initiatives.
