Pretty cool watch. Probably old news by now on any serious scale though.

He basically isolated some low frequencies (which means they penetrate materials well) of plane engines and calculated based on a few of them a precise location where the video was taken.

Haven't seen this video but I think Veritasium or Tom Scott did a video about this like a decade ago. They got creepily accurate results. Mains hum be scary

This particular method is triangulating background aircraft doppler sounds, getting their approximate speed and distance from the doppler shape and looking it up in air traffic logs to find valid matches. it needs multiple data points though.

it's not perfect of course, there are plenty of light aircraft that dont have accurate tracks available, and it would be easy to spoof or mask, but it's very cool bit of work that could be added to the toolkit for people that really want to use it.
