ANC makes use of advanced kind of tech to actively cancel noise. ANC works when, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to counter it. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (inverted noise) to make zero which results in a reduced level of noise.
The Apple AirPods Pro (2nd Gen) have ANC allowing you to listen at lower volume levels, good for your ears as you don't need to crank up the device volume to outcompete background noise.
