Conference microphones play a very important role in a high-quality conference. Most people think that the first-class video signal is the most important, but it is not. From the visual effect of the video conference, good audio performance is still the most important. How to achieve an audio quality and obtain the effect of being in the same room as the remote participant? This involves the selection of conference microphones. Today, I will show you how to choose a conference microphone.
The communication of important information between participants in a video conference is achieved through dialogue. Therefore, it is very important to choose conference microphones with high-quality audio effects.
The conference microphone is a very important equipment in the deployment of the conference room, which has a very obvious effect on the sound effect of the entire system. In order to reproduce the original sound in the conference system and achieve the effect of being in the same room as the remote participants, when choosing a conference microphone, you should start with the following aspects:
1. Use directional conference microphones, because non-directional microphones have poor resistance to external interference and are easy to mix into other sound sources. They must be used together with an echo canceller.
2. The selected frequency should be around 150Hz-10KHz. This range includes half of the sounds of musical instruments and humans.
3. It is not suitable to choose a high-impedance microphone, because of its high sensitivity and easy to be interfered by external signals.
4. It is not advisable to choose a conference microphone with too high sensitivity, because too high sensitivity will cause the sound to fluctuate or produce howling, which is easy to damage the speakers, so as long as the sensitivity is stable.
