In order to obtain the original sound in the conference system and achieve the effect of being in the same room with the remote participants, when selecting the conference microphone, the following aspects should be taken:
1, to use omni-directional microphones, because there is no directional microphone has poor resistance to external interference, easy to mix into other sound sources, they should be used together with the echo canceller.
2, the choice of frequency should be about 150Hz-10KHz is appropriate, this range includes half of the instrument sounds and human voice.
3, should not choose high-impedance microphone, because of its high sensitivity, susceptible to external signal interference.
4, should not choose the microphone with high sensitivity, because the high sensitivity will make the sound suddenly big or small or produce whistling phenomenon, easy to make the speaker damage, so as long as the sensitivity can be stable.
