New system uses wheel sensors to monitor vibration and counteracts it with finely tuned soundwaves

Jaguar Land Rover (JLR) will usher in new noise-cancelling technology on the facelifted Range Rover Velar, XF and F-Pace, claiming it will reduce driver fatigue and enhance refinement. 

Developed by Israeli noise-cancelling specialist Silentium, the Active Acoustics system uses sensors on each wheel to monitor vibrations and produces a sound wave through the cabin’s Meridian sound system of the exact frequency needed to remove the unwanted noise. 

JLR claims that this will allow unexpected noises from potholes and rough surfaces to be “isolated and removed”, with the ability to lower individual noise ‘peaks’ by 10dB and overall noise levels by 3-4dB. 

The manufacturer cites research that says reducing vehicle occupants’ exposure to low-frequency noises can help prevent fatigue on longer journeys. Tired motorists, it says, react 16.72% slower on average to hazards or unexpected events than fully alert drivers.

The Active Acoustics system is being rolled out in line with Jaguar Land Rover’s Destination Zero strategy, which aims to achieve a future of zero emissions, zero accidents and zero congestion. 

An added benefit of the system for new plug-in hybrid versions of the Velar and F-Pace P400E is that the electrified powertrain can be “refined for lower CO2 emissions and efficiency with no impact on driver experience”. 

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.”

This is more significant than it sounds. Eliminating noise in electric cars is a significant challenge because the lack of motor means you hear everything. So I suspect they have an eye here on the future

Sound of peasants disappearing under the wheels?

Sound of the breakdown of various mechanical parts standard on JLR products?

Hide the uncouth nature of the Ingenium engines?

The sound of the planet screaming about the excessive weight of JLR products?

The sound of owners complaining about warranty work at service desks country wide  

Only some of this is tongue in cheek.

Love it Paul.  Maybe Mercedes could retro fit it to for owners of some poorly built cars in the early 2000s such as the ML class, perhaps Porsche for IMS bearing failure or bore scoring on their engines, BMW for turbo engine failure or swirl flaps being sucked into engines, VW group for dieselgate...just JLR for issues is it?

How about other manufacturers use it Paul to cover the noise of their owners - Mercedes for some early 2000s reliability, IMS bearing failure or bore score on some Porsches, BMW engine problems, VW group dieselgate, Tesla build quality.  Great idea

They did it first I think, though not on the suspension.  But as a long time user of high end noise cancelling headphones I'd much rather they fix the rattles through engineering than the acoustic pressure you experience when using noise cancelling tech.  Hey Autocar, any chance you could add some comments to the articles rather than just cut and pasting?  I'd be happy to review. Surely someone in Autocar knew about Lotus from 12 years ago, maybe, possibly.....

Not sure if Lotus were first but there's been others too.  I do not see anywhere in the story where JLR claim to have invented the tech, besides articles would be pretty tiring if they had to list previous manufacturers of tech in every article.

And funny how other manufacturers are actually making cabins noisier by manufacturing exhaust noise.

Nothing new, current CR-V hybrid has noise cancelling tech as standard, and costs a lot less than a RR/LR
