How do I set up my Huawei phone s dual microphones?

To set up a Huawei phone's dual microphone, turn on Settings - Other Settings - Dual Microphone Noise Cancellation on or off.

The principle of the dual-microphone noise reduction function is to collect the environmental noise through one of the microphones, and then do the reverse phase processing through the internal DSP of the mobile phone to cancel out the noise.

Dual microphones are generally used to collect the sound of mobile phone calls, and the other is used as an auxiliary microphone to collect environmental noise, although the sound is reversed, but once the sound reaches a large enough, the double microphone noise reduction will lose its effect, because the sound cancellation has a certain threshold (range), and the general cancellation sound is about 6 35db (decibels) (the approximate parameters of the normal noise reduction range, the actual parameters are subject to the design standards of the mobile phone itself), also In other words, if the noise cancellation range is exceeded, the noise will also be transmitted to the mobile phone call.

Another function of noise canceling microphone on some mobile phones is the sound collection of recording, through the pickup of multiple microphones, the sound of recording will also be enhanced, of course, this function is not applicable to all mobile phones, subject to the actual situation.

Open your phone's settings, find "Additional Settings" in the settings and turn it on, then find Dual Microphone Noise Cancellation on or off;

Click the hook on the right side of the dual microphone drop to turn it on, one of the dual microphones is mainly used to collect the sound of mobile phone calls, and the other is used as an auxiliary microphone to collect environmental noise.
