active road noise cancellation: JLR introduces noise cancellation technology for select models, Auto News, ET Auto
According to a release, 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 reduction in exposure to low-frequency noises up to 300Hz is claimed to help prevent driver fatigue on longer journeys.
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.
Iain Suffield, Jaguar Land Rover refinement advanced technologies specialist, said, “We are committed to creating a haven for our customers, and this new technology allows us to remove unwanted noises from the cabin. It makes the experience more tranquil, improving passenger wellbeing and helping to reduce cognitive load and thus reaction times. This research is all part of the journey to Destination Zero”.
Reducing accidents and improving driver wellbeing is a 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.
The 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 for effective functioning, the release said.
