Solving The Problems Of Video Conference Omni-directional Microphone

Solving the problems of video conference Omni-directional microphone

The video conference microphone is a very important device in the conference room deployment. In the video conference, audio has become one of the most important. The exchange between participants is mainly realized through audio dialogue or discussion, with good video and ordinary audio ratio. Having good audio and regular videos is much more useful. Of course, due to the fact that the emphasis on audio products is not very high, the probability of audio problems during the video conference is high.

First, the sound during the audio call is light

This is mainly because the voice from the other side is very light. It takes a lot of effort to understand what the other party is talking about. The problem usually lies in the collection of sounds. This party can test its own speakers or horns first, and use a local computer to play tests to see if the volume of the play is large enough. If it is determined that the audio frequency of the party is normal, you can basically judge the problem. In the upstream, generally can adjust the device input (recording) volume size, which requires special signature, is to adjust the recording volume, but there is lots of people who only would rather adjust the speaker's voice than use the recording volume size adjustment.

Second, the noise during the audio call is relatively large

The size of the noise mainly has two aspects. First, during the conference, there may be noise sources such as fans and air conditioners. However, the general conference audio pickup products that do not have special noise processing, resulting in noise being picked up. Secondly, it is the audio uplink. The volume of the recording is too large, resulting in a slight movement with large sound collection and noise. Of course, sometimes there are some functions in the conference software, such as noise reduction and squelch. In the event of a conflict with the software, it is also likely to cause noise.

Third, hear the echo during the video conference

During videoconferencing, it was found that they could hear their own voices and they came back. For example, when many mobile phones use hands-free hands, they are also prone to such situations. This is mainly because audio equipment is not selected well. Therefore, the front-end audio equipment is also required to be matched, and its own echo cancellation function is needed. This can ensure that the other party's voice comes out of the speaker and will not be transmitted from the pickup part of the product, resulting in an echo. If the conditions are limited, the sensitivity of the audio input device can be reduced, the distance between the pickup device and the speaker, the power amplifier can be increased, the sound can be reduced, and the echo can be improved by the distance effect.
