摘要
An active noise control (ANC) headrest comprises a speaker configured to produce antinoise that destructively interferes with frequencies of ambient sound, and a microphone configured to receive feedback comprising a combination of the antinoise and the ambient sound. The headrest further comprises a position sensor configured to detect a position of a flange to which the speaker is mounted relative to a center section of the headrest. The headrest further comprises processing circuitry configured to control the speaker to produce the antinoise based on the feedback and the position detected by the position sensor.
