New Jaguar Land Rover noise cancellation tech helps reduce driver fatigue
According to JLR, the technology lowers unwanted noise peaks by 10dB.
The folks at Jaguar Land Rover have unveiled a new noise cancellation technology that aims at removing unwanted road and tyre sounds from the cabin.
Making its introduction on the new Jaguar F-Pace and Range Rover Velar, the technology provides a quieter and more refined experience for drivers and passengers.
According to JLR, the technology lowers unwanted noise peaks by 10dB and overall noise levels by 3-4dB and 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 that 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.
