Jaguar Land Rover fights driver fatigue with noise canceling technologyOctober 9, 2020
The new system uses wheel sensors to monitor vibration and counteracts it with finely tuned sound waves.
British automaker Jaguar Land Rover (JLR) will introduce new noise cancellation technology in the updated Range Rover Velar, XF and F-Pace, claiming it will reduce driver fatigue and improve ride quality.
Developed by Israeli noise-cancellation specialist Silentium, Active Acoustics uses sensors mounted on each wheel to monitor vibrations and creates a sound wave through the Meridian sound system at the precise frequency needed to eliminate unwanted noise.
JLR says this will “isolate and remove” unexpected noise from potholes and rough surfaces, with the ability to reduce individual noise “peaks” by 10 dB and overall noise levels by 3-4 dB.
The manufacturer cites a study that says reducing low-frequency noise exposure to car occupants can help prevent fatigue on long journeys. It says that tired motorists are, on average, 16.72% slower to react to hazards or unexpected events.
Active Acoustics is part of Jaguar Land Rover’s Destination Zero strategy to achieve a zero-emissions, crash and congestion future. An additional benefit of the system for the new plug-in hybrid versions of the Velar and F-Pace P400E is that the electrified powertrain can be “tweaked to reduce CO2 emissions and improve efficiency without sacrificing the driver.”
Ian Suffield, Advanced Technology Officer at Jaguar Land Rover Refinement, said: “We strive to create a haven for our customers, and this new technology allows us to remove unwanted noise from the cab. This makes travel more relaxed, improves the well-being of passengers and helps to reduce cognitive load and therefore reaction time. All this research is part of the path to the goal. “
