Active Noise Cancelling (ANC) microphones have one element facing the mouth and the other away from it. The inner element samples voice input and the outer samples background noise coming towards the user. Electronic white noise is added to cancel out the background effects. This configuration is highly accurate but produces lower values in the Dragon SNR, in part because this is designed for the cheaper pressure gradient microphones included with the software.
