Active Noise cancellation (ANC) is a process that eliminates unwanted environmental audio by identifying unwanted sound waves and creating precisely inverted signals to neutralize the original sound, thereby reducing distracting background noise to the greatest possible extent.
ANC is the most known type of noise cancellation and has mostly been used in over-ear headphones. This technology has become so small and battery efficient, as now it can be used in true wireless in-ear earphones.
The system is based on microphones that “listen” to the sounds outside and inside of the earphone, an ANC chipset inverting the soundwaves, and a speaker inside the earphone canceling the outside sound by the neutralizing soundwaves.
As of now, Huawei launched a number of wearables equipped with Active Noise Cancellation technology to offer the optimal noise-reducing performance. The list of product includes:
Moreover, Huawei FreeBuds Pro delivers the best noise-canceling performance yet on a Huawei audio product with an industry-leading noise cancellation rating of 40dB.
Active Noise Cancellation (ANC) modes:
Smart Dynamic Mode: The earphones automatically adjust the appropriate noise reduction mode based on external noise.
Cozy Mode: In a quiet environment like libraries, this feature helps you reduce the noise of air conditions, computers, and other machines to the right degree of noise reduction, which comfortable and natural.
Standard Mode: When you in the street or cafe and want to stay away from the noise and immerse yourself in music and games, this is a perfect mode for an improved user experience.
Ultra Mode: While taking a flight or subway, this feature effectively reduces the heavy low-frequency noise and allows you to enjoy peace and quiet.
