Claim 9:
10. An active noise control system, comprising:
a processing module, configured to determine an expected noise control curve of performing active noise control on a target object; determine an expected noise control weight value of active noise control, according to the expected noise control curve; and determine a reference noise weight value and an expected filter frequency response of active noise control;
a filter coefficient calculation module, configured to determine 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
a noise control module, configured to perform noise control processing on an external noise signal of the target object using the target filter;
wherein the processing module is further configured to:
determine expected residual noise energy;
determine an expected residual noise energy spectrum curve; and
determine the expected residual noise energy based on the expected residual noise energy spectrum curve;
the filter coefficient calculation module is specifically configured to:
determine the target filter, according to the expected noise control weight value, the reference noise weight value, the filter frequency response, the expected residual noise energy, and the filter model.
