ANC makes use of more advanced kind of tech to reduce unwanted ambient sounds. How it works, it studies the sound pattern of incoming noise and generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 therefore "diluting" the noise.
