How Active Noise Cancellation Works on New JLR Vehicles

Jaguar Land Rover are on the offensive, with a new range of facelifted models to excite the market. These models bring a range of new and enhanced features and today we’re sharing some information on one of those features – Active Road Noise Cancellation.

You may have heard of Active Noise Cancellation in headphones, and in principle, the concept it similar. With the latest Jaguar Land Rover products such as the 2020 F-Pace, XF and Range Rover Velar, Active Road Noise Cancellation is available with the Meridian sound system optioned.

The system works by using 8 sensors to collect road noise and vibration data.

It’s not just microphones but accelerometers that are picking up on these vibrations, so lower frequency vibrations up to 300Hz are detected too.

These unwanted road noises are cancelled out by the speakers, which fire out sound waves that “oppose” those generated by the noise.

JLR claims the system can lower unwanted noise peaks by 10dB and overall noise levels by 3-4dB, and because decibels work on a logarithmic scale, this is actually very noticeable by passengers.

The system is also smart enough to adjust the level of noise cancelling needed based on how many passengers are in the car.

Here’s the press release with more.


Jaguar Land Rover has revealed new noise cancellation technology that removes unwanted road and tyre sounds from the cabin and provides a quieter and more refined experience for drivers and passengers.

The technology, introduced on the new Jaguar F-PACE, new Jaguar XF and Range Rover Velar, is capable of lowering unwanted noise peaks by 10dB and overall noise levels by 3-4dB – the equivalent of turning down the in-car sound system by four ‘steps’. This significant reduction in exposure to low-frequency noises up to 300Hz can help prevent driver fatigue on longer journeys**. 

Fatigue affects the ability of a driver to deal with hazards or unexpected events, with tired motorists recording an average reaction time increase of 16.72% compared to those fully alert*. Reducing accidents and improving driver wellbeing is a key part of Jaguar Land Rover’s journey to Destination Zero: an ambition to make societies safer and healthier and our environments cleaner through relentless innovation.

Active Road Noise Cancellation, enabled by Silentium’s Active Acoustics technology, uses sensors on each wheel to constantly monitor the vibrations from the road surface and calculates the opposite phase sound wave needed to remove the noise heard by the occupants. By monitoring in real-time, unexpected noises from potholes or rough surfaces can be isolated and removed.

The cancellation sound is played through the Meridian sound system, with the vehicle monitoring cabin occupancy to optimise Active Road Noise Cancellation performance for all drivers and passengers. The technology offers a no-compromise solution to balancing refinement, vehicle weight and driving dynamics for a complete premium feel.

Active Road Noise Cancellation combines with Engine Noise Cancellation on the new Jaguar F-PACE and new Range Rover Velar with the P400e plug-in hybrid (PHEV) powertrain to further enhance the sense of wellbeing. The pioneering system allows the PHEV variant to be refined for lower CO2 emissions and efficiency with no impact on driver experience.
