How to select a video conference microphone
The conference microphone in a video conference is absolutely a very important device and it depends on it. It has a significant effect on the overall system sound effects of the entire system.
The choice of microphone mainly starts from four aspects.
First of all, the frequency response is appropriate around 150Hz ~ 10KHz, this range basically includes the vocal and general musical instrument sound;
Secondly, the sensitivity should not be too high. Too high sensitivity can easily cause whistling or the phenomenon of loud and small sounds. It is easy to damage the speakers, so the sensitivity can be stable;
Third, the impedance is high and low, the high-impedance microphone has high sensitivity and is vulnerable to external signal interference;
Finally, to select a directional microphone, because the non-directional microphone is resistant to external interference, easy to mix with other sound sources, this kind of microphone must be used in conjunction with the echo canceller.
