How quiet is the allelectric Joby Aviation aviation aircraft in hover? Here’s our founder JoeBen Bevirt with a calibrated sound level meter and an explanation!
“Over here behind me is our aircraft in hover. At 55 dB, this is more than 1000 times quieter than a helicopter taking off at 90 dB.
As you can see and hear, it is not just quiet quantitatively, but also qualitatively, with noise that blends into the background.
It is not the low frequency ‘wop wop’ of a helicopter that travels for miles and penetrates buildings, nor is it the highfrequency whine of a drone.
Our goal was to mimic the character of natural sounds like the wind or the ocean.”
Watch the film to catch JoeBen’s full description and to hear it for yourself go to 00:3000:40 to see how quiet the Joby aircraft is during hover!
