Active Road Noise Cancellation

As any frequent flyer will likely know, headphones with active noise cancelling (ANC) use microphones on the outside to hear ambient sounds - like the drone of an airplane cabin - then work out the opposite waveforms, and play that into your ears. The result is a dramatic reduction in background noise.

How It Works:

• Microphones and accelerometers pick up road noise entering the cabin.
• An advanced audio processor analyzes the detected noise and predicts how it will transfer into the cabin.
• The system produces an anti-noise wave in real time to counteract unwanted sounds.
• This anti-noise wave is played through the vehicle’s speakers, effectively reducing disruptive road noise.

Benefits:

• Suppresses low-frequency road noise below 500 hertz for a quieter ride.
• Provides a more peaceful and relaxing interior, ensuring a premium driving experience.

Active Road Noise Control reduces the in-cabin noise level by cancelling out unwanted sound originating from the tires and road surfaces while driving.

It is no surprise that car manufacturers want to cut down on the background thrum of road noise. A survey conducted by Harman audio company found road noise to be the biggest auditory distraction reported by drivers.

To minimize road noise, Active Road Noise Cancellation detects road noise entering the interior through accelerometers and microphones, then generates anti-phase sound waves through an algorithmic calculation in the controller, outputting them via speakers to cancel out the noise. The vehicle thus effectively suppresses low-frequency road noise below 500 hertz, improving serenity.

With the reduction of wind noise being another critical factor for ensuring a relaxing ride, double-laminated acoustic glass that features a noise-absorbing film in between two glass layers is also utilized in many Genesis models. Filling the gaps between the vehicle body and door panels are triple-layered weatherstrips that further minimize noise intrusion.
