摘要： Embodiments of active noise control (ANC) headphones and operating methods thereof are disclosed herein. In one example, a headphone for ANC includes a speaker, an internal microphone, a processor, and a filter function module. The speaker is configured to play an audio based on a first audio source signal. The internal microphone is configured to obtain a mixed audio signal comprising a noise signal and a second audio source signal based on the audio of interest played by the speaker. The processor is configured to determine a current system parameter of the ANC headphone based on the mixed audio signal at a first time point and determine a current parameter of a filter function module based on the current system parameter of the ANC headphone and pre-tested data. The filter function module is to perform ANC based on the determined current parameter of the filter function module.
