No okay okay. You probably know that sounds are waves that travel through air right? What this does is predict what waves the engine and the road makes and then through the speakers of the car emit a wave that is completely in the opposite direction.
Imagine a sound has the imagenary value of 1. Then the onboard computer picks this up and emits a sound of the imagenary value of -1 through the speakers.
1 + -1 = 0 which means you're left with no noise.
Hope it helps, if it's not clear then i'll try to make it clear through images and stuff.
