Active Noise Cancellation is an acoustic arms race against phase inversion. Ambient noise must be sampled, computed, inverted, and played back before soundwaves physically reach your tympanic membrane—a window of less than 35 microseconds.

AirCore Pro uses four microphones per earbud. Two feedforward mics monitor exterior office chatter and engine drone, while two internal feedback mics listen to ear canal resonances to calibrate real-time cancellation filters 48,000 times per second.
