ACTIVE NOISE CANCELLATION (ANC)NoobNox said:It is my understanding that all 4cyl Noxes and Terrains have the ANC regardless of which stereo package you have.
look in the headliner, there should be a couple mics in the vehicle, one above the driver and one in the rearRhythmiC said:I don't think my 4cyl has this feature... but I can't here the nox or the road cause I got the upgraded pioneers![]()

Not at freeway speeds at all, it's at low RPMs and typically city driving. ANC is there to cancel out exhaust noise at lower RPMs where 4 cylinder engines are the worst. And I think the one in our 'Nox conked out as we were hearing quite obnoxious boominess at low rpm (less than 2k) driving in the city today. If it acts up tomorrow it's a trip to the dealer.Narg said:The ANC is only for a very low rumbling noise made by the I4 at highway speeds. It does not add any other noise reduction in any other way. The vehicle is quiet due to a lot of effort put into the build of the car by GM and sound deadening materials in the engine compartment and doors.
The low rumble noise made by the I4 is due to it's gas saving features. GM didn't like the sound either, thats why they added the ANC to the I4 versions.

This link gives an excellent technical explanation of how it works:

Yes! Larger 4 cyl engines (2.0L and up) tend to have an unpleasing exhaust sound at low rpm's and that's what the ANC helps eliminate inside the cabin. Actually IMO all 4 cyl. engines have an unpleasing exhaust sound at all rpm's, but then I'm biased towards the sound of V8's.tnmats said:ANC is there to cancel out exhaust noise at lower RPMs where 4 cylinder engines are the worst.
