Active Noise Cancellation: How does ANC work?

Active noise reduction technology, or ANC, is an invaluable asset in the world of headphones. It uses noise-cancelling drivers to eliminate unwanted background noise, providing an immersive listening experience. But how exactly does it work?

ANC is based on an ingenious system made up of microphones, a chipset dedicated to noise reduction and a speaker integrated into the headset. Together, these elements create an ideal sound environment by canceling external noise with reverse sound waves. To understand better, imagine that the ambient sound volume outside is +2 dB, and the ANC removes 2 dB inside the headphones, bringing it to zero.
Active noise reduction can be implemented in a variety of ways through in-chipset signal processing methods, including:

Feed-forward ANC system: It uses a microphone located outside the headset to anticipate noises to be eliminated.
Feedback ANC system: It integrates a microphone inside the headset to react to surrounding noises.
Hybrid ANC System: This system combines both feedforward and feedback for optimal noise reduction.

There are also several types of noise reduction, each suited to different situations:
● Active noise reduction: This method uses microphones and speakers to eliminate background noise and improve your hearing experience. It is commonly used in over-ear headphones and, thanks to the miniaturization of components, it is now present in wireless in-ear headphones.
● Passive noise reduction: In this approach, specially designed headphones actively block unwanted noise. It is used in both over-ear headphones and in-ear headphones, where the earphones block noise from entering.
● Active and dynamic noise reduction: This technology uses microphones and speakers to automatically adapt to your environment, providing digital adjustment of the level of noise reduction.
● Active and adjustable noise reduction: It gives you total control over the intensity of the noise reduction, thanks to manual adjustment.
● Transparency Mode: This mode allows you to stay aware of your surroundings while listening to music without removing your headphones.
● Adjustable Transparency Mode: You can choose the level of ambient noise you want to filter through, while continuing to listen to your music.

Traveling with the ANC is a unique experience. Whether you prefer to immerse yourself in a podcast, enjoy your favorite music or simply block out ambient noise, ANC-equipped headphones are the ideal accessory. Keep in mind that activating this feature may result in increased power consumption, but it is a real ally for travelers, especially with hybrid noise reduction capable of neutralizing low aircraft frequencies and louder noises. passenger treble, giving you an oasis of sonic tranquility in the sky.
