Active Noise Cancellation (ANC): Everything you need to know

Active Noise Reduction (ANC) is a process that can eliminate the harmful environmental audio by identifying harmful sound waves and creating precise inverted signals to cancel out the original sound, thereby minimizing the process of dispersing background noise.

ANC is the most famous type of noise cancellation and is mainly used in ear-hook headphones. This technology has become so small and battery-efficient because it can now be used in true wireless in-ear headphones.

The system is based on the following microphones: they “monitor” the sound inside and outside the headset, the ANC chipset inverts the sound waves, and the speakers inside the headset neutralize the sound waves to eliminate external sounds.

Up to now, Huawei has introduced many wearable devices using active noise reduction technology to provide the best noise reduction performance. The product list includes:

  • Huawei FreeBuds Pro
  • Huawei FreeLance Pro
  • Huawei FreeBuds 3i
  • Huawei FreeBuds Studio, etc.

In addition, Huawei FreeBuds Pro provides the best noise reduction performance to date on Huawei audio products with an industry-leading 40dB noise reduction level.

Active Noise Cancellation (ANC) mode:

Intelligent dynamic mode: The headset will automatically adjust the appropriate noise reduction mode according to external noise.

Comfort mode: In a quiet environment like a library, this function can help you reduce the noise of air conditioners, computers and other machines to an appropriate level of noise reduction, which is comfortable and natural.

Standard mode: When you are on the street or in a cafe, stay away from noise and immerse yourself in music and games. This is the ideal mode to improve the user experience.

Super mode: When taking an airplane or subway, this function can effectively reduce heavy low-frequency noise and let you enjoy peace and quiet.
