>Leaf blowers and cars driving past are exactly the kind of thing that ANC works well on, a fairly constant noise.

I can tell you haven't heard a leaf blower in a while, if ever. The revving the operators inevitably do causes it to bounce up and down over the spectrum at completely random-seeming intervals. Punches right through ANC, windows, doors, walls.

As if that's not bad enough they pollute more than a gigantic SUV because of how much oil they burn being a two-stroke.
