Israel-based Silentium, a technology company specializing in creating personal in-car sound environments, says it is ramping up the global roll-out of its Active Road Noise Cancellation (ARNC) technology after being selected by automotive supplier Hyundai Mobis as the preferred ARNC software provider. Three production models from other manufacturers, equipped with the company’s ARNC technology, have already been released to the market.
After several years’ development of the software, Jaguar Land Rover was the first car maker to announce integration of Silentium’s ARNC in three of its new vehicles in October 2020. Having signed an MoU last year, Silentium and Hyundai Mobis are now collaborating on a global vehicle production program for an unnamed brand.
Sang Hun Lee, Asia managing director at Silentium, commented, “Our active acoustics technology can reduce, cancel and enhance sound inside any vehicle, and can work on any infotainment system and speakers in any car – no extra investment needed on types or placement of speakers. You can already find our broad-band noise cancellation software in Jaguar and Land Rover vehicles, and we can’t wait to start a wider global roll-out thanks to our new partnership with Hyundai Mobis.”
The company’s ARNC is similar to that found in a pair of noise-canceling headphones, but the company says it is more advanced as it manipulates a larger volume of air. Up to six strategically positioned accelerometers on a vehicle’s chassis monitor unwanted road noise and send a signal to an onboard control unit, which plays an equivalent anti-noise signal through the vehicle’s speaker system. The pressure waves from both the unwanted exterior noise and manufactured anti-noise reach occupants’ eardrums at exactly the same time and cancel each other out.
