Adaptive Noise Cancellation

Adaptive Noise Cancellation (ANC) is a technique that reduces unwanted sounds by using a second microphone to pick up the noise and then generating an "anti-noise" signal that cancels it out. The system continuously adjusts this anti-noise in real-time, learning and adapting to changing noise environments. This way, it effectively minimizes background sounds—like engine noise or chatter—making audio clearer. ANC is used in headphones, microphones, and other audio devices to improve listening comfort and sound clarity in noisy settings.
