These two screenshots are from the same measurement of four F35s taking off, measured at the Winooski Post Office at the top of the traffic circle. The ‘headline numbers’ are 114dB-C and 108dB-A. The noise exceeds 100dB-C for about 15 seconds per jet at this downtown location. The first screenshot is zoomed in on the 4 jets, I caught the first jet mid-flight at the beginning of the plot. The first three jets were taken with C-weighting, the fourth with A. You can see the rumble is attenuated following the peak of the A-weighted jet.
