Digital system from ADI ensures peace and quiet in Hyundai cars
Hyundai’s planned RANC (Road-noise Active Noise Control) system is designed to drastically reduce the driving noise inside a car. The system can analyze different types of noise in real time and compensate by generating inverted sound waves. The various types of driving noise that the new technology can process include resonance noise between tires and wheels, for example, or rumbling noises coming from the road.
The automaker has recognized the importance of a low-noise interior for the driving experience of the occupants and thus for the market acceptance of the manufacturer. The company chose A2B technology primarily because it has the low latency required, said Kang-Duck Ih, Research Fellow at Hyundai. Working with ADI, Hyundai’s engineers have been able to reduce the cost, weight and design complexity of such a system to the point where it is suitable for mass deployment.
The A²B technology also reduces the weight of the cabling by up to 75% and thus benefits both the fuel consumption of the cars and the overall system costs, said Patrick Morgan, vice president, Automotive Electrification and Infotainment at Analog Devices.
A²B is the industry’s lowest latency high-speed digital interconnect technology. Audio and control data can be transmitted along with clock signals and power on the same unshielded twisted pair cable. Until now, the use of automotive noise compensation systems has failed due to the lack of a cost-effective, low-latency network technology that can efficiently connect input-side sensors to a central processing unit. ADI’s A²B technology significantly reduces the cost and complexity of cabling compared to traditional analog-based noise reduction systems.
