This is another noise measurement of four F35s taking off to the North. This was taken from a home off of Bellevue St in Winooski. There is an expansive view from south to north overlooking all of Winooski, hospital hill and into downtown Burlington. This is also close to the end of the northern end of the runway, so the jets arc from horizon-to-horizon just forward of this location.
Unlike past measurements much closer to the runway where there were high decibels for relatively short periods, this better illustrates what many further from downtown endure. Noise in the low-100s (106.5dB peak — unweighted — in this case), but a duration of about two minutes above 90dB.
Note in this case the first two planes were measured with C-weighting, the second two planes with A-weighting (the industry standard, but always a lower number), before I switched back to C-weighting to measure the rumble into the distance.
Click on the picture to see it bigger than full-screen. I plan to list a number of previous noise measurements made over the past few months in this format and site. As well as a primer on how to interpret the graphs for those that need to brush up on their decibels and such.
This morning was far, far louder than we could remember. I did not have my meter nearby so I could not measure. We are in BTV just off East Avenue. They do not take off over us but no matter. Framed pictures on the wall hummed and vibrated the entire time all of them were taking off. The walls vibrated, the windows vibrated in their frames. We could not hear each other talk. I wondered if the afterburners were on, it was so very much louder than we could remember so far.
That is way too loud for someone to endure on a regular basis. It's like a railroad train suddenly going through your backyard at 100mph, close to the house. Nothing to see, but it's right there. Amazing.
I should mention this measurement was taken on the porch of this home, NOT from inside the house!
