Claim 0:
1. A method for active noise control, comprising:
determining an expected noise control curve of performing active noise control on a target object;
determining an expected noise control weight value of active noise control, according to the expected noise control curve;
determining a reference noise weight value and an expected filter frequency response of active noise control;
determining a target filter, according to the expected noise control weight value, the reference noise weight value, the expected filter frequency response and a filter model; and
performing noise control processing on an external noise signal of the target object using the target filter;
wherein the method further comprises:
determining expected residual noise energy, comprising: determining an expected residual noise energy spectrum curve; and determining the expected residual noise energy based on the expected residual noise energy spectrum curve; and
the determining the target filter, according to the expected noise control weight value, the reference noise weight value, the expected filter frequency response and the filter model, comprising:
determining the target filter, according to the expected noise control weight value, the reference noise weight value, the expected filter frequency response, the expected residual noise energy and the filter model.
