Many problems in practical applications of omnidirectional microphones
First of all, we need to define the use occasions and scope of use of omnidirectional microphones. It is defined as below 40 square meters An audio processing device used in small video conference rooms.
First: the sound is not clear enough
The pickup distance of the omnidirectional microphone, The pickup distance of omnidirectional microphones for video conferencing provided by the vast majority of manufacturers is within a radius of 3 meters, so we try not to exceed this range when using them. This ensures that the omnidirectional microphone can pick up the sound clearly, and we can hear the other party’s voice accurately and clearly.
Second: Poor audio call quality
A remote video conference is generally established with two or more parties, in which case There is bound to be uneven performance of microphones, and different processing of audio and echo. Then we need the presenter or other staff responsible for the overall video conference scheduling to perform some necessary operations, such as when we need someone to speak. Then turn on the other party’s microphone, or raise your hand to speak, etc., which can not only improve the efficiency of the meeting, but also improve the quality of the audio call.
Third: echoes or noises
During remote conferences, it is often difficult to avoid hearing some echoes or noises, causing these problems The reasons are more complicated and we need to analyze. First of all, the operating system of the PC will also process the audio. The video conferencing software will also perform some processing on the audio. The omnidirectional microphone itself has its own echo cancellation function, so at this time, we should selectively turn off some audio processing functions of the PC and the video conferencing software. Then appropriately reduce the pickup volume of the omnidirectional microphone and the volume of the speaker. I believe that most of the audio problems can be solved through these steps.
Fourth: Listening without voice or unable to speak
During the meeting, it is impossible to hear or speak through the omnidirectional microphone. At this time, we first Check whether the connection is normal, or replace it with another USB port of the computer. This is because of the stability and compatibility of the USB port. For desktop computers, it is better to connect it to the USB port on the back of the host, which is more stable.
