Wouldn't that require a microphone near the source of the noise though?
Noise cancelling headphones have a microphone
outside of the headphones, which is amplified, inverted and then subtracted from the signal that drives the headphones. Doing something similar to reduce cabin noise would surely require microphones that are external to the cabin, otherwise you'd create some kind of noise cancellation loop that perpetually removes and re-adds the noise.
