Selling Silence: Hyundai Developing Advanced Noise Cancellation System
Noise-canceling technologies have become a handy little tool wedged inside the belt of many automakers. Aimed at reducing unpleasant road noise, most systems invert incoming sound waves to produce an exact negative of the ambient sound you don’t want to hear. They work best when you don’t notice them, which is pretty much always, but Hyundai Group claims there’s more work to be done before the tech is perfect.
As a result, the Korean manufacturer has developed an upgraded version of its current active noise control setup (ANC), one it calls “the world’s first Road Noise Active Noise Control.” Rather than simply piping in sounds designed to offset road noise, the new system (referred to as “RANC” by the automaker) also analyses in-cabin sound to make adjustments to help nullify unpalatable engine and road drone.

The same rules apply, just about anything besides the “Help Me with my First World Problem Car Purchasing Dilemma” is on the table. If you’ve seen it on an automotive message board, let’s tackle the issue here. I need your content!
No more begging, let’s get back to Craig the Audiophile looking to cancel his noise-cancelling Grand Cherokee:
Piston Slap: Cancelling Chrysler's Noise Cancellation?

Hey Sanjeev, (*facepalm* –SM)
I have a 2015 Jeep Grand Cherokee SRT, and I’m bit of a music buff. One of the first things I dispensed with was the factory Harman Kardon speakers. I replaced the sub with a JL stealth box. Now I have a pretty big problem with the factory stereo and its the automatic noise cancellation.
When the transmission is in normal D mode and or eco mode is on, it uses the factory stereo to cancel out the drone of the engine. Unfortunately, the noise cancellation is calibrated for the weaksauce factory sub. Now it sounds like one of those bass CDs from the ’90s as I hold speed or decelerate. I’ve asked the dealer how to get rid of this thing, to which they said “you can’t.”
I’m not so convinced.
Any ideas?
