Claim:
1. An anti-noise headset device, comprising: an audio receiving module configured to receive a plurality of audio signals in a plurality of periods; a control module electrically coupled to the audio receiving module, configured to store the audio signals received by the audio receiving module from a first period to an Nth period as sound data and to compare the audio signal received in an (N+1)th period with the sound data so as to generate a relevance value, wherein N is an integer larger than zero; wherein when the relevance value is smaller than a threshold value, the control module filters out a portion of the audio signal received in the (N+1)th period, wherein the portion of the audio signal received in the (N+1)th period is relevant to the sound data, wherein when the relevance value is larger than or equal to the threshold value, the control module adds the audio signal received in the (N+1)th period into the sound data, wherein when the relevance value is larger than or equal to the threshold value, the control module deletes the audio signal received by the audio receiving module in an earliest period in the sound data.
