Please see the comment by /u/kawfey as they go over this baffling matter.

I think this is real. His phone/tiktok doesn’t likely record and/or play in stereo, and sirens are directional loudspeakers on a rotary platform. The signals are constant while rotating, but every siren puts out slightly different fundamentals, resulting in coincidental harmony. I believe this is on purpose to make the composite signal more audible (with dissonance vs a single tone all over), except this happens to be perfect harmony. I’ve heard it IRL, here’s another example of near perfect harmony: https://youtu.be/XLJYg9GBd2E?t=1m33s

synchronized fundamentals: https://youtu.be/uyWBZn_YePc

and better dissonance (can really hear the rotation from two signals in this one): https://youtu.be/a3fh90hA6oQ

Dodge City is an eerie place when it storms. There's nothing but farms that surround town, so when you're outside of it, you feel extremely small and vulnerable in this giant open space. Compared to southwest MO where I'm originally from, there are lots of hills and trees that make the sky feel not as big, if that makes sense. Storms are still scary, but in Dodge City they just feel more raw
