1. The appearance of noise in the meeting can be roughly manifested in the following three scenarios: all or most of the attendees hear the noise. This scene may be someone in an online meeting
The microphone (phone) has detected noise, and the following methods can be used to troubleshoot it: the host checks the noise prompt and reports it. If a participant is noisy, report it
Prohibit wheat and remind attendees to conduct self-examination. Attendees who have been banned from speaking due to noise should first determine if the environment they are in is really noisy. They can use Tencent Meeting to set the audio settings
The "Detect Microphone" function is used for microphone quality and environmental noise self-test. If the environment is indeed noisy, the entry location can be changed to a quiet place. If it is not convenient to change the location,
You should try to choose earphones as much as possible and reduce the microphone collection volume. After ruling out the possibility of environmental noise, if the noise still exists, it is also necessary to rule out microphone quality issues that may cause incorrect data acquisition
Error, if possible, you can try replacing the microphone. For example, you can try switching between the earphone and the built-in microphone of the terminal device to see if the noise is eliminated.
2. This scene may be due to someone's microphone (phone) collecting noise during an online meeting. The following methods can be used to troubleshoot: the host checks the noise prompt and reports it,
If a participant reports loudly, they will be banned from speaking and reminded to conduct self-examination. Participants who have been banned from speaking due to noise should first determine whether their environment is really noisy
Miscellaneous, you can use Tencent Meeting to set the "detect microphone" function in the audio for microphone quality and environmental noise self-test. If the environment is indeed noisy, you can change your membership
Place to a quiet place. If it is not convenient to change the location, try to choose earphones to join and reduce the microphone collection volume. After ruling out the possibility of environmental noise, if the noise still exists
It is necessary to rule out microphone quality issues that may cause collection errors. If possible, you can try replacing the microphone, such as switching between the earphone and the built-in microphone of the terminal device to see if there is any noise
Eliminate. If there is noise but no noise is reported, it is likely a network connection issue. Other participants did not hear any noise, only specific individuals heard it.
3. There are many situations that can cause computer speakers to have noise, such as speakers being interfered with, poor contact of interfaces or connecting wires, poor quality of the speakers themselves, and so on- Generally speaking, electricity
Brain sound systems are mostly active speakers, and there will inevitably be amplifiers inside, so noise is inevitable. The noise of active speakers can be roughly divided into electromagnetic interference, mechanical noise, and
Thermal noise, etc. Electromagnetic interference can mainly be divided into power transformer interference and stray electromagnetic wave interference- Generally speaking, power transformer interference is caused by magnetic leakage in the power supply of multimedia speakers
The effect of installing a shielding cover on the transformer is very obvious when conditions permit, which can block magnetic leakage. The shielding cover can only be made of iron materials. We should
Try to choose products from big brands with solid materials, and using an external transformer is also a good solution. Stray electromagnetic wave interference is quite common, such as speaker wires and frequency division
Devices, wireless devices, or computer hosts can all become sources of interference. Try to keep the main speaker as far away from the computer host as possible under allowable conditions, and reduce the number of surrounding wireless devices. Speaker placement
