What must happen within milliseconds for ANC cancellation to be effective?
Answer
The entire sequence from sound detection to anti-noise emission.
The entire operational flow, encompassing sound capture, analysis, signal calculation, and projection of the inverse wave, must occur very rapidly to negate the original wave before it has fully passed the user's ear.
