Why is Your Land Rover’s Cabin Noise Increasing? Resolving Active Noise Cancellation Glitches

Land Rover is known for providing comfort, luxury and a satisfying serene driving experience. But this experience can soon become worse if you hear more road, wind and engine noise than usual. So, it is important to keep your Land Rover’s Active Noise Cancellation in proper care as neglecting any issues could lead to expensive future repairs.

How Does Active Noise Cancellation Function in a Land Rover?

l The Land Rover interior cabin includes the tiny microphones that constantly listen for unwanted sounds coming from outside.

l The Land Rover’s complex computer instantly processes these sounds and creates a mirror image known as anti-noise sound waves.

l These anti-noise waves are then broadcast through your audio system’s speakers through a process called destructive interference where they cancel out the offensive road, wind and engine noises.

Reason Behind the Land Rover Cabin Getting Noisier

Faulty Microphones - The ANC system depends heavily on these mics for picking up unwanted noises. If these get blocked, unplugged or wear out over time then the system cannot hear properly to cancel it out.

Software - Modern Land Rovers have sophisticated computers and if the ANC software encounters a bug, crashes due to a corrupted update or fails due to any electrical surge then it may stop working suddenly.

Speaker Troubles - An ANC requires all speakers in your car to operate correctly to deliver all those vital anti-noise waves and if any speaker is damaged or disconnected then you’ll hear more noise.

Control Module Failure - The electronic control unit is known to be one of the most important components of your ANC. If this component faces certain issues like power surge, water damage or reaches the end of its lifespan then it can shut down the entire system.

Aftermarket Overhauls - Certain instances also might affect the ANC system such as if you have recently installed a new audio system or made any necessary changes to your interior and by unintentionally affecting the ANC system’s calibration then it can lead to a decrease in the performance.

How to Diagnose and Fix ANC Glitches?

l Most of the Land Rovers include a built-in computer that reports the errors. Use an OBD-II scanner or have an authorized dealer run a detailed system check. Look for any codes related to the ANC or audio system.

l It is also important to inspect the interior of your cabin especially near where the microphones and speakers are located. Look for any signs such as water damage, clogged grills or loose wiring and ensure all the speakers are producing sound.

l If the software is outdated or the software has any bugs then you can ask your Land Rover dealer for any ANC software updates or check if your vehicle supports any over-the-air (OTA) updates.

l A simple reboot can also clear some of the minor glitches. Turn the vehicle off then disconnect the battery for 10-15 minutes and then reconnect it. This procedure can sometimes reset the ANC control module.

l If you have modified your sound system recently or replaced any interior components then your ANC system needs to be professionally recalibrated using factory specifications. And this should only be performed by an authorized dealer.

l Check for warranty if your ANC failures are covered under Land Rover’s basic warranty. If your Land Rover is found to be under warranty then the repair could be free.

How to Keep Your Cabin Serene in the Future?

l It is essential to regularly check and clean any visible ANC microphones to prevent any blockages.

l Ensure that the software and electrical work is done by the authorized Land Rover service centers.

l It is necessary to avoid any aftermarket audio or interior modifications which could affect speaker or microphone placement.

l It is also important to address any electrical warnings that are appearing on your dashboard.
