What is an active noise reduction system in a car and how does it work?

Imagine: you are racing along the track, enjoying your favorite music. No annoying engine roar, wind noise or tire screeching. This is not fiction, but reality thanks to Active Noise Canceling (ANC) technology. Let's find out what it is and how this magical system works. Also, your car can become more comfortable and practical if you use tuning accessories, a large assortment of which is available in our product catalog.

We fight noise with cunning

Unlike noise isolation, which absorbs noise with materials, ANC "deceives" it. The system works as follows:

• Microphones - we listen to the enemy: special microphones placed in the car interior pick up unwanted noises (engine noise, road noise, wind noise).
• Noise analysis: the electronic control unit analyzes the collected information and creates a "mirror" noise signal.
• Speakers are our weapon: special speakers in the car's acoustic system reproduce a "mirror" signal in antiphase with the original noise.

The result is magical silence

The waves of the output noise and the "mirror" signal are superimposed on each other with the opposite phase, as a result of which their mutual suppression occurs. As a result, the driver and passengers enjoy a much quieter and more comfortable cabin.

Advantages of active noise reduction

• Improved comfort: ANC helps reduce cabin noise, reducing driver fatigue and increasing the comfort of all passengers during the journey.
• Improved sound quality: thanks to the reduction of extraneous noise, the quality of music reproduction and audio system speakers is improved.
• Conversationability: With active noise cancellation, it's easier to maintain a conversation with passengers during the ride without having to raise your voice.

Dependence on system quality: The effectiveness of ANC depends on the quality of the speakers, microphones and electronic control unit. More expensive systems provide better noise reduction.

Conclusion

Active noise reduction is a modern technology that allows you to significantly increase the comfort of a car ride. When choosing a new car, pay attention to the presence of this function and feel the difference.
