> only works on near constant noise of airplanes and other near constant sources of noise. That is simply not true - at least in my experience with an old model of Sony headphones. It's possible that prediction plays some role, but I bought mine with specific purpose of silencing neighbor's kids. They work really well with this kind of sporadic, random noise and the difference between turning on active cancellation and just passive attenuation due to ear muffs is very noticeable. I'm talking about low-frequency noises that are mostly transmitted through the vibrations in the walls and floors - feet hitting the floor while running, ball bouncing of the walls and so on.
