Abstract:
Embodiments of active noise control (ANC) headphones and operating methods thereof are disclosed herein. In one example, a headphone for ANC includes a speaker, a microphone, an echo-cancel module, and an ANC module. The speaker is configured to play an audio based on a first audio source signal. The microphone is configured to obtain a mixed audio signal including a noise signal and a second audio source signal based on the audio played by the speaker. The echo-cancel module is configured to reduce the second audio source signal from the mixed audio signal based on the first audio source signal to generate an echo-cancel audio signal. The ANC module is operatively coupled to the echo-cancel module and configure to generate a noise-controlled audio source signal to be played by the speaker based on the echo-cancel audio signal and the first audio source signal.

Claim (Index 11):
The headphone of  claim 8 , wherein the ANC module comprises:\n an ANC filter configured to filter the echo-cancel audio signal to generate a second cancellation signal; a second adder configured to couple the second cancellation signal and the first talk-through audio signal to generate the noise-controlled talk-through audio signal; and a first limiter operatively coupled between the ANC filter and the second adder and configured to compress an amplitude of the second cancellation signal based on the amplitude of the second cancellation signal.
