This is not a trick question, but it's a tricky situation. Sounds moving away from you become lower in volume by the inverse square law. So there's a perhaps rhetorical question whether you'd still be able to detect something moving that fast by the time it Doppler-shifted beyond processing. It absolutely works with light. Distant and fast-receding galaxies red-shift out of visible "colors" into infrared. You would need a very loud sound source, moving away very fast, with a starting frequency in the low end of your hearing range in the first place. There are people who can't intake below 30 or 40Hz, which is a whole octave above the typical healthy 20Hz lower limit. So results would vary across the population.

It's a long-distance view of a squirrel on an electrical wire that's got inches of snow on top of it. Squirrel is bumping the snow off a few inches at a time. Took me a WHILE to figure that wasn't an insect on a frosted window.

We knew this in autumn of 2020. I mean, I'm glad the study was formally conducted and analyzed, but this study merely refined the data from nationwide spikes to county-specific spikes in the neighborhoods of games. It also doesn't account for the college football season spreads of 2020 and 2021. Again, I'm glad to see it formalized and connected explicitly to these cities and counties on these dates. That will be more convincing to people who are predisposed to believing evidence and science.

The rear view mirror of history tends to point out only the highlights. Regime changes, landmarks, major wars, that sort of thing. You can only test students on so many things, and there are huge gaps in expected common knowledge. When history teachers look back on the last 100 years from now, what do you think the highlights on school tests will be?
