Noise cancellation apparatus and method

A noise cancellation method implemented by a noise cancellation apparatus having a reference microphone, an error microphone, and a speaker, comprising:

• determining a target noise cancellation parameter based on a matching degree feature value, and the matching degree feature value is related to a matching degree between a headset and an ear canal of a user;
• obtaining a target inverse phase noise based on the target noise cancellation parameter, wherein the target inverse phase noise is used to reduce an ambient noise obtained by the reference microphone;
• and
• performing audio mixing processing on a played downlink audio signal and the inverse phase noise to obtain a mixed audio signal, and the mixed audio signal is played by using the speaker,
• wherein a distance between the error microphone and the speaker is a first distance, a distance between the reference microphone and the speaker is a second distance, and the first distance is less than the second distance.

A noise cancellation headset control apparatus, comprising:

• one or more processors;
• and
• a memory, wherein the memory is configured to store program instructions, and the one or more processors are configured to invoke the program instructions to perform steps of:
• presenting an input interface;
• providing a noise adjustment module in the input interface, wherein the noise adjustment module comprises indications of a plurality of non-uniformly arranged noise cancellation level indexes, and an interval between indications of adjacent noise cancellation level indexes is related to an adjustment step between noise cancellation levels;
• receiving a switch control signal, wherein the switch control signal is used for setting enabling or disabling of a noise cancellation function of a noise cancellation headset;
• and
• receiving, by using the noise adjustment module, a setting on a noise cancellation level index, wherein the noise cancellation level index is used to indicate a noise cancellation level of the noise cancellation headset.
