Analog Devices (ADI) and Hyundai Motor Company plan to launch the automotive industry’s first all-digital road noise cancelation system using the former’s Automotive Audio Bus (A2B) technology.
Hyundai plans to adopt ADI’s A2B technology for its audio connectivity and infotainment applications across its fleet.
Dr Kang-Duck Ih, research fellow at Hyundai, said that as an early adopter of A2B, the Korean corporation realized the potential of the technology for not only its Road-noise Active Noise Control (RANC) systems but for other vehicle applications fundamental to passenger and driver experience.
Dr Ih said, “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 reduces noise within the cabin and can analyze various types of noise in real time and produce inverted soundwaves.
Patrick Morgan, vice president automotive electrification and infotainment at Analog Devices, added, “We have collaborated closely with Hyundai to architect its all-digital RANC system that leverages our A2B technology to reduce equipment cost, weight and design complexity, and in turn, improve overall fuel efficiency – helping solve several challenges of the electronic RANC system.”
