Hyundai Developing New Revolutionary Cabin Tech

Technology / Comments

Hyundai's interiors are about to get a lot quieter.

Many modern cars now come equipped with noise-canceling tech to make the cabin as quiet and refined as possible. Taking this a stage further, Hyundai has announced the development of the world's first Road Noise Active Noise Control (RANC) system that dramatically reduces noise inside the cabin.

Building on Hyundai's current Active Noise Control technology, which actively reduces noise by emitting sound waves inverted to incoming noise, ANC is a software-driven technology that analyses sound in the cabin to decrease engine and road noise instead of blocking noise through sound insulation.

The new system can analyze various types of noise in real-time and produce inverted soundwaves. It can also eliminate different types of road noises such as sounds created between tires and wheels or rumble sounds coming up from the road.

Using an acceleration sensor, the system calculates the vibration from the road to the car and the control computer analyzes road noise. According to Hyundai, it only takes 0.002 seconds to analyze the noise and produce an inverted soundwave. Based on tests evaluating road surface, vehicle speed, and different seating positions, the RANC was able to reduce in-cabin noise by 3dB, which is roughly half the noise level of a cabin without the RANC technology.

The revolutionary road noise-canceling tech will also reduce the amount of unsprung weight in a vehicle since it utilizes fewer sound-insulating parts and dampers. Hyundai hasn't said when it plans to roll out the RANC technology, which has taken the automaker six years to research and develop, but the automaker has hinted it could be implemented into future electric and fuel-cell models. A photo released by Hyundai also shows the Genesis GV80, so the tech could be added to the new flagship SUV. Since there's noise generated from the powertrain, Hyundai believes it's even more imperative to reduce road and wind noise.

"RANC is a remarkable technology which takes existing NVH technology to the next level. We will continue to take the leading position of NVH technology and deliver the highest level of quietness to customers," said Gangdeok Lee, a researcher at NVH Research Lab.
