Abstract: Active noise cancellation method is provided, including: when the headset is in an ANC working mode, obtaining a first group of filtering parameters, and performing noise cancellation by using the first group of filtering parameters. The first group of filtering parameters is one of N1 groups of filtering parameters prestored in the headset. The N1 groups of filtering parameters are respectively used to perform noise cancellation on ambient sound in N1 leakage states. The N1 leakage states are formed by the headset and N1 different ear canal environments. In a current wearing state of the headset, for same ambient noise, noise cancellation effect obtained when the first group of filtering parameters is applied to the headset is better than noise cancellation effect obtained when another filtering parameter in the N1 groups of filtering parameters is applied to the headset. N1 is a positive integer greater than or equal to 2.

Abstract: An active noise cancellation (ANC) method applied to a headset includes obtaining a first group of filtering parameters, and performing noise cancellation using the first group of filtering parameters. The first group of filtering parameters is one of N1 groups of filtering parameters prestored in the headset. The N1 groups of filtering parameters are respectively used to perform noise cancellation on ambient sound in N1 leakage states.
