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 and XF plus the 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.
Jaguar Land Rover NZ general manager, Steve Kenchington, said that “in pursuit for safer roads and fewer accidents, the Jaguar Land Rover engineers are delivering significant advancements in vehicle safety technology”.
“The noise-cancelling technology is an impressive and innovative approach to battling driver fatigue – a serious and harmful problem many Kiwi drivers overlook,” he said.
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 per cent compared to those people 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.
