First all-digital Road Noise Cancellation System
Analog Devices Collaborates with Hyundai Motor Company

Analog Devices announced a strategic collaboration with Hyundai Motor Company where Hyundai plans to launch the automotive industry’s first all-digital road noise cancellation system leveraging ADI’s Automotive Audio Bus (A2B®) technology. Hyundai also intends to more broadly adopt ADI’s A2B technology for its fundamental audio connectivity and infotainment applications across its automotive fleet.

A2B reduces cabling weight by up to 75 percent and improves automotive fuel efficiency and total system costs. ADI’s A2B is the industry’s lowest latency, high-speed digital interconnect technology distributing audio and control data together with clock and power over a single, unshielded twisted-pair wire.

Current deployment of automotive road noise cancellation systems has been constrained by the availability of a cost-effective, low latency networking technology that efficiently connects required input sensors to a central processing unit. ADI’s A2B technology significantly reduces associated wiring harness cost and complexity found in traditional analog-based road noise cancellation system deployments.

Hyundai’s RANC system dramatically reduces noise within the cabin of a vehicle. The system can analyze various types of noise in real-time and produce inverted soundwaves. 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.
