Active Noise Cancelation
The primary new feature of AirPods Pro is new Active Noise Cancelation. The ANC system uses two microphones and some clever software tricks to analyze and cancel out external noise. In fact, AirPods Pro will analyze and adapt the outside noise about 200 times per second.
Users will also be able to enable a “transparency mode,” which will allow users to hear what’s going on around them. This isn’t simply disabling ANC. Instead, it takes advantage of vent systems and microphones to specifically adjust noise cancelation so that users can hear the outside world along with their music.
