Noise cancelling technology has been around for a while and is employed by nearly every automaker. Whether it's dense foam insulation, thick carpets, technological innovations, or recommending a certain tire compound, there are many ways automakers work to keep road and engine noise from permeating the cabin.

Hyundai is taking those traditional methods of sound-blocking even further with the world's first Road Noise Active Noise Control (RANC) system, which the company says "dramatically reduces" cabin noise.

RANC is the next step in active noise control technology and works by emitting sound waves that have been inverted to incoming noise. Think of it like two magnets repelling each other.

Previously, active noise control technology only allowed predicted noises to be able to be muted.

"RANC is a remarkable technology which takes existing noise, vibration, and harshness (NVH) technology to the next level," said Gangdeok Lee, a Research Fellow of NVH Research Lab, "We will continue to take the leading position of NVH highest level of quietness to customers."

The new RANC technology, which took six years to develop, analyzes road noise in real time, using an acceleration sensor, and calculates the vibration from the road to the car. A computer analyzes the results and the system optimizes the signal in less than 0.002 seconds, adjusting accordingly.

RANC is able to calculate the sound independently for the driver, passenger, and rear seats.

Hyundai testing revealed that RANC is able to reduce in-cabin noise by 3dB, roughly half of what is currently experienced in Hyundai vehicles.

This technology has further reaching implications. Because Hyundai will not have to rely on heavy, dense foams and carpet to help with cabin noise, they are able to lessen the amount of or remove those elements from vehicles, allowing for more passenger space and less weight. In turn, this could make vehicles more fuel efficient.

The system will be mass produced by Harman.

Hyundai Motor Group has completed domestic and American patent applications for the location of sensors and signal selection method, the core technology of RANC.

The technology will begin to be applied to an upcoming Genesis model.

Frightening security

Boston Dynamics' robot to patrol Kia factory

The robot is being tested as a security patrol unit.

Breaking into an auto manufacturing facility was already a very bad idea, but new security tech being tested by Hyundai Motor Group makes it downright terrifying as well. In addition to cameras, sensors, and armed security guards, would-be burglars at a Kia plant in South Korea now have to face off with a semi-autonomous robot dog.

The Boston Dynamics quadruped robot, named Spot, is being tested as a safer and more effective way of providing security patrols to the plant. The dog is one of several robots designed and tested by the firm, which has long terrified the internet with its physically capable electronic beings.

If you haven't seen it, the Boston Dynamics robot dog is frightening enough on its own, so it's an excellent choice to provide factory security. The robot uses an integrated thermal camera and 3D LiDAR to detect people around it, and can monitor high-temperature situations and fire hazards. It can be controlled remotely through a secure webpage, which allows personnel to see what's going on in the factory without putting themselves in danger.

The robot is capable of navigating tight spaces and can identify issues not visible to the human eye. It's also able to semi-autonomously navigate its environment, and has been developed with task management and deep learning-based vision technology. Boston Dynamics says that its tech can be expanded to other types of robot platforms.



The robot dog is currently in the pilot stage at Kia's plant in South Korea. It will be used to support late-night security patrols and increase safety for workers. Hyundai Motor Group will assess the robot's effectiveness and suitability for the job before expanding its use in other industrial sites.
