Original Abstract Submitted
embodiments of this application disclose a noise cancellation apparatus and method. the noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. the main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. the noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. after the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. in addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted.
