Primes

• Signal Extraction
  • In active noise cancellation, the entangled observation at the ear is the desired audio summed with ambient cabin noise.

    This sourceReviews adaptive-filter active noise cancellation, the live noise-model-plus-anti-phase-discriminator extraction in headphones.

    Supported in partVerified against the publisher's abstract

    The tutorial's abstract states the ANC principle (a cancelling antinoise wave from secondary sources) but never states the ear-observation model of desired audio plus ambient cabin noise.

    “Active noise control (ANC) is achieved by introducing a cancelling "antinoise" wave through an appropriate array of secondary sources.”

Mechanisms

• Counter-Signal Injection
  • Cancellation is only ever as good as the phase and amplitude match

    This sourceExplains that active cancellation depends on phase and amplitude matching and signal predictability, while mismatch can amplify noise rather than cancel it.

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Read against the text for 1 of 2 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
