The solution to the microphone current sound and nuisance sound

When using a microphone, you may encounter the problem of current sound and nuisance sound, which not only affects the quality of recording, but also may affect the effectiveness of communication. Here are some solutions based on search results:

Replace or check the microphone

Replace the microphone If the microphone itself is of poor quality, it may produce current sound and nuisance sound. In this case, you can choose a higher quality microphone, especially professional recording microphones, which have lower condenser circuits and circuit noise, which can reduce the generation of current sounds45.
Checking the microphone

If the microphone has a murmur, you should first check that the microphone is intact, that no foreign objects have fallen into it, and that the edges of the vibrating paper have been peeled off and damaged. If this occurs, the microphone can be repaired or the microphone can simply be replaced

Adjusting Computer Settings
Adjusting the Volume Settings Volume that is too high can easily cause the microphone to produce a garbled sound. You can reduce the current sound by adjusting the volume setting of your computer1.
Adjusting Microphone Properties When using a microphone on your computer, you can reduce the current sound by adjusting the properties of the microphone. To do this, open the Control Panel on your computer, go to the Sound Control Panel, click on the Recording option, right-click on the microphone when you see it inside Recording, and select the Properties option. In the Properties screen, click on the Advanced option and choose a channel that suits your microphone, the higher the frequency the better the sound quality in general. Next, in the Level option, slide the Microphone Enhancement option to the far left, i.e. set it to 0.0dB.

Using External Devices

Using an isolation transformer Adding an isolation transformer between the microphone and the amplifier can isolate the current loop in the cable, thus reducing the transmission of current sound45.
Using noise reduction equipment Some specialized noise reduction equipment can effectively reduce the interference of current sound, such as noise reduction filters and noise reduction pre-processors45.

Improving the use environment

Avoiding magnetic field interference Magnetic fields and substances with sound waves, such as cell phones, electric fans, and other devices, may cause the microphone to produce current sounds and nuisance sounds. These devices should be avoided as much as possible near the microphone3.

Keeping the computer dry If the computer components become damp, this may also cause current and noise to be generated. Make sure that the computer is placed in a good environment to avoid moisture2.
The above methods can help you solve the problem of microphone current sound and nuisance sound. If the above methods do not solve the problem, then it may be hardware damage, you can try a new microphone!

Do you use a three-prong plug for your computer’s mainframe power supply? Is the home power supply with a ground wire?
First, the computer chassis need to be reliably grounded; with a wire connecting the host and the ground ridge can touch the ground heating pipe, bed frame and other metal is also OK).
Second, the northern region in the fall and winter seasons should use a humidifier to maintain a certain level of humidity in the indoor air, to prevent static electricity in the equipment, furniture and the body of a large number of accumulations.
In addition, the signal is not good, poor contact at the joints can also cause a murmur
