F35 Northbound Takeoff Noise Chamberlain School
This was recorded in the Chamberlain School parking lot. The jets were making their takeoff to the northwest, so their exhaust noise wasn’t as directed towards the school as they might be with a south takeoff.
The first four jets were measured using C-weighting (unweighted, recording most of the low frequencies), and the second four planes were measured using industry-standard A-weighting (all lower frequencies removed). You can see where I switch to A-weighting between the groupings of four planes and the background noise drops 20dB. Even with A-weighting, the four jets peaked between 94 and 97 dB-A. With C-weighting, all four jets were between 101 and 110 dB-C.
The ‘headline number’ is 109.7 dB-C. The variations between jets seemed to be slightly different flight paths after liftoff. How closely the tail exhaust of the jet aligns with the measurement position has shown to make big differences. I believe a south takeoff would result in higher readings.

The governor has authority to order a stop to the F-35 training flights in such a densely populated neighborhood and so close to this school and to six other schools. Authority expressly provided in the constitution. He orders the F-35 training flights from the runway only 800 yards from the Chamberlin School. From a runway that blasts hundreds of kindergarten through 5th grade children every morning and every afternoon. From 8 to 16 times a day. The Air Force, the CDC, the EPA, the WHO, and the Vermont Department of Health all say noise at this level can impair learning and cognitive development. NATO warned against mingling such military jets and schools. But the governor does not listen to the science when it comes to the F-35.
