Why So Loud! Geeking Out On Airline Data, Physics And Mapping
summary
Uses FlightAware to pull historical tracks (about 400 tracks over two weeks), compares broadcast ADS‑B data and optional USB dongle capture, models loudness with sone and sound‑pressure formulas finding typical event levels near 90–100 dB, applies spreading and absorption loss to build a distance field and render a heatmap, discovers localization error from float32 vs float64 error, and produces a usable map showing the preferred town sits in low‑noise blue/green so moving is acceptable.
