How to activate the active noise cancellation feature in the Chevrolet Equinox?
3 Answers
The active noise cancellation feature in the Chevrolet Equinox does not require manual activation. When noise is detected, the system automatically emits sound waves that are the inverse of the noise, significantly reducing the noise level and maintaining a quiet cabin environment. The principle of the active noise cancellation system involves first collecting the waveform characteristics of the noise, then processing it through a built-in chip to generate an inverse wave, which is then canceled out by high-fidelity speakers. The Chevrolet Equinox is a model launched by Chevrolet, with body dimensions measuring 4652mm in length, 1843mm in width, and 1684mm in height.
Oh man, I get excited when friends ask about this—just helped my younger brother with his Equinox. The active noise cancellation in this car doesn’t need manual activation at all! As long as the engine is running and the audio system is powered, it works quietly in the background. Here’s the key—you must ensure all the car’s speakers are functioning properly. There are small, button-like microphones near the rear seat headrests—don’t let seat covers block them or let kids damage them. These mics pick up low-frequency cabin noise, then the audio system generates opposing sound waves to cancel it out. If you suddenly notice increased humming inside the car, first check if the audio system is malfunctioning or if a child seat in the back is pressing against the microphone ports. These electronic systems are especially sensitive to wiring modifications—adding a subwoofer haphazardly will definitely mess up the noise-canceling feature.
Once in the workshop, I encountered a customer complaining about excessive noise in the Equinox. The issue actually stemmed from the Active Noise Cancellation (ANC) system. This feature doesn't require manual activation—it starts automatically upon ignition. The key is to check the status of the rear microphones—there's one hidden near each C-pillar, about the size of a button battery. If they're completely covered by aftermarket leather seat covers, the system will simply stop working. I've tested models with and without ANC on highways, and the 3-decibel difference is quite noticeable. It's advisable to regularly inspect the speakers for distortion—I once encountered a case where a cracked speaker cone caused ANC malfunction. Be extra cautious with audio modifications. Last time, a customer experienced severe low-frequency resonance after upgrading the amplifier, which ended up burning out the ANC control module with visible smoke.
