Analog Devices collaborates with Hyundai on road noise cancellation system
Published: 27 January 2020 - Christian Lynn
Analog Devices (ADI) has announced a strategic collaboration with Hyundai Motor Company (HMC), where Hyundai plans to launch an all-digital road noise cancellation system, leveraging ADI’s Automotive Audio Bus (A2B) technology to accomplish this task. Hyundai also intends to broadly adopt ADI’s A2B technology for its fundamental audio connectivity and infotainment applications across its automotive fleet.
“As an early A2B adopter, we realised the potential of this technology for not only our Road-noise Active Noise Control (RANC) systems, but also for other vehicle applications fundamental to passenger and driver experience,” said Dr. Kang-Duck Ih, research fellow, Hyundai: “The low latency guaranteed by A2B enabled us to implement this groundbreaking RANC technology and accelerate its deployment to mass production.”
Hyundai’s RANC system dramatically reduces noise within the cabin of a vehicle. The system can analyse various types of noise in real-time and produce inverted sound waves. For example, there are different types of road noises that the new technology can process, such as resonant sounds created between tires and wheels or rumble sounds coming up from the road.
“We have collaborated closely with Hyundai to architect its all-digital RANC system, to reduce equipment cost, weight, and design complexity, and in turn, improve overall fuel efficiency – helping solve several challenges of the electronic RANC system,” said Patrick Morgan, vice president, automotive electrification and infotainment, Analog Devices. “ADI’s work with Hyundai demonstrates A2B’s increasing viability and further distinguishes Hyundai’s vehicles in today’s marketplace.”
