Among the new updates found in the JL Wrangler Order Guide and the updated JLU Wrangler Order Guide we’ve recently posted, is a feature called “Active Noise Control” listed under the Electronic Infotainment Sys Group and Alpine Premium Audio System option. With this feature, the Jeep Wrangler will receive active noice cancellation technology for the first time.
Known as “Active Noise Cancellation” on the current Jeep Grand Cherokee and Chrysler Pacifica, the technology utilizes a combination of the audio system and strategically placed microphones (four in the Grand Cherokee and Pacifica) to introduce opposite-wave sound to the cabin in order to offset unwanted sounds, leading to a quieter cabin (by reducing NVH).
In the Jeep Grand Cherokee Summit and SRT models, the Active Noise Cancellation system also counteracts exhaust drone by create counteracting sound waves to keep the vehicle quieter at highway speeds.
