What is ANC - How does Noise Cancellation work? - Bang
WEBActive Noise Cancellation (ANC) uses a noise cancelling system to reduce unwanted background noise. 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 cancelling the outside sound by the neutralising soundwaves.
