How does Active Road Noise Cancellation work?

You hear lots of road noise while cruising along the highway. What if we remove those noises entirely? You will have a relaxing and soothing experience, right! You are correct; this is what Active Road Noise Cancellation does. The technology actively removes unwanted tyre and road sounds from the cabin.

Furthermore, as you know, while cruising on highways, you hear lots of tire sound coming from the road inside the cabin. Such sound for a prolonged period is annoying and adds to the discomfort. This technology really helps to avoid such an annoying sound.

Besides, this technology provides a refined and quieter experience for drivers and passengers. The system can reduce the annoying sounds by 10dB.


The active road noise cancellation reduces overall sounds by 3-4dB. This reduction is equivalent to reducing the volume of the sound system by four steps. In general, you won’t believe tires and road creates that much sound right? But the fact is they do. They produce lots of noise.

Furthermore, the significant noise reduction with low frequency up to 300Hz reduces overall driver fatigue on long and tiring journeys. The long trips often come with driving fatigue. Fatigue reduces the ability to cope with unexpected events on the road, causing severe accidents.

According to research, a tired driver’s reaction time increases by 16.72% when compared to the normal driver. It’s because the human body gets exhausted as it needs to stay alert for a longer duration, specifically on long journeys.

The above research shows that fatigue can lead to accidents. So, this technology highlights the improvement in drivers’ health as well as reducing accidents.

What is active road noise cancellation?

First of all, this technology is enabled by a set of sensors. This technology uses sensors that monitor vibrations from the road surface. At the same time, it also calculates the opposite phase sound wave needed to cancel out that sound heard by passengers.

Besides, these sensors monitor both things in real-time. Hence, they cancel out sounds from potholes and rough road surfaces. The system isolates and removes the sound in real-time.

Furthermore, the cancellation sounds are played by the sound system. The sound system uses vehicle monitoring cabin occupancy to improve the performance of active road noise cancellation for occupants. Hence, this technology offers refinement and an uncompromised premium experience. Besides, the technology also balances out vehicle weight, refinement, and driving dynamics as a whole, giving you a premium experience.

Also, active road noise cancellation, engine noise cancellation, and plugin hybrid powertrain further reduce the sounds. Thus, it keeps the driver more relaxed and ready to react in hazardous situations.

In conclusion, active road noise cancellation is the next step towards a peaceful driving experience, setting up new industry standards.
