Active Noise Cancellation™ (ANC) System (Accord, CR-V, HR-V, Insight, Odyssey, Passport, Pilot and Ridgeline)



What’s the Benefit?

This feature provides a quieter cabin, helping to make for greater comfort and less fatigue.

 

The Feature:

The ANC system eliminates noise caused by both VCM cylinder deactivation and exhaust noise. 

  • The ANC controller uses a front ceiling-mounted microphone and a rear tray microphone to detect any “booming” sound in the cabin associated with cylinder deactivation. 
  • It then emits a mirror “anti-noise” signal through the audio system’s speakers, which effectively cancels those booming sounds and creates a quieter passenger compartment. 
  • ANC is always working, even when the audio system is turned off.
