Why is the Xiaomi Mi 2S call very quiet?

Hi! Dual-microphone noise reduction technology is currently the most widely used noise reduction technology, one microphone is used by ordinary users when talking to collect human voices, and the other is configured on the top of the fuselage, with background noise collection function, convenient for collecting surrounding environmental noise. In this way, when the user is talking, the microphone at the top collects the noisy background sound, and then after a series of hardware accurate filtering and enhanced real-time signal operation processing, it is compared with the background noise information database, and then superimposed on the original call signal according to the principle of signal cancellation to achieve the effect of eliminating noise and improving the quality of the call.

At the same time, this technology can not only effectively improve the call quality in noisy environments, but also reduce the volume appropriately in a quiet environment to avoid the leakage of call content.

It is recommended that when you use a Xiaomi mobile phone, try to keep the call microphone close to your mouth to ensure that there is a significant difference in the volume of your voice in the call MIC and the noise cancelling MIC, or you can press and hold the noise cancelling MIC with your finger to ensure that the voice of the call MIC is recorded, so that your problem can be solved.

If the call pickup mic at the bottom of the phone is too far away from your voice source (mouth) when you are talking, the distance between the call MIC at the bottom of the phone and the noise reduction MIC on the back of the phone may be about the same, and the difference in sound size is not enough, which will cause the system to judge your voice as background noise, so as to filter, resulting in the other party not being able to hear your voice clearly.
