摘要:
The present invention discloses a noise canceling system and method, a smart control method and device and a communication equipment. Said smart control method includes: when it is detected there is no voice signal output at a receiving end of a communication equipment, receiving an outside noise signal from a reference microphone away from ears and a detection signal from a monitoring microphone near ears; implementing performance analysis on said received outside noise signal and said detection signal to estimate a noise reduction performance curve after said feed-forward active noise cancellation; and regulating parameters of the control circuit in said feed-forward active noise cancellation according to said estimated noise reduction performance curve and the preset noise reduction performance curve to make a difference between said estimated noise reduction performance curve and said preset noise reduction performance curve within a preset range.
