Jaguar Land Rover has revealed a new Active Road Noise Cancellation technology for Jaguar cars and SUVs. The new technology will be introduced on new Jaguar F-PACE, new Jaguar XF and Range Rover Velar. The new technology boasts to remove unwanted road and tyre sounds from the cabin enabling a quieter and comfortable cabin experience for both the driver and the passengers.
The new Silentium Active Acoustics technology is able to reduce noise peaks by 10dB and overall noise levels by 3-4dB which is equivalent to turning down the in-car sound system by 4 steps. This also lowers the exposure to frequency by 300Hz. The significant reduction in the low-frequency translates to reduced driver fatigue on longer journeys. According to the National Center for Biotechnology Information: The Effect of Road Traffic Noise on Reaction Time, noise fatigue affects the average reaction time of the tired driver and increases it by 16.72% as compared to an alert motorist.
The Active Road Noise Cancellation technology employs 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. The system works in real-time and unexpected noises from potholes or rough surfaces are also isolated and removed. The Meridian in-car sound system plays a cancellation sound in the cabin monitoring cabin occupancy to optimise Active Road Noise Cancellation performance for all the occupants.
The new Active Noise Cancellation works hand-in-hand with the 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 performance. The noise cancellation system reduces accidents and the driver’s wellbeing along with his ability to deal with hazards or unexpected events. The new technology is in-line with the brand’s Destination Zero, an initiative to make societies safer, environment cleaner and healthier through new innovations.
Jaguar Land Rover is also developing new technologies and materials to meet the changing mobility world.
