I often hear the sound of electricity next to the computer, is it tinnitus or electricity?

Or the sound of the current, you can judge for yourself, method:

Leave the computer and go to a quiet environment, and then listen quietly, if there is still an electric current sound, it means that it is tinnitus, if not, it means that it is a sound from the computer.

If it is the current sound emitted by the computer, it is likely that there is a "discharge" place in the computer, such as **poor contact, if it is a desktop computer, disassemble it and check it yourself; If it's a laptop.

You can go to the repair place to check it.

Most likely, it's the sound of a fan.

The current is generally inaudible, and the current can only be heard when some elements are generated. For example, transformers.

If this feeling is only felt next to the computer, then it must be the effect of the computer on the human body.

It may be a real current sound, usually an alternating current sound, usually due to the power supply or power strip.

It is also possible that computer radiation has a specific effect on the human body.

It should be electromagnetic noise, not tinnitus.

There are high-frequency circuits in the host power supply, CPU circuit, graphics card circuit, hard disk, etc., which generally produce high-frequency electromagnetic noise. Some noise can interfere with the audio circuitry, which can be clearly heard with headphones.

Those who don't hear are just not paying attention or not being able to discern.

The current sound in the computer is generally only emitted by the power supply, and other graphics card chassis CPU or something are fan sounds, and there will also be current sounds when the audio connected to the computer is in poor contact or aging, you can judge for yourself.

Yes, the computer has a voice changer, and there will indeed be an electric current sound, and the computer cooling fan and mechanical hard disk will also emit sound. In the dead of night, the sound will be very noticeable.

Maybe it's the sound of a computer fan!

Laptop.

Reasons for sizzling sounds:

1. Mechanical hard disk.

sounds. HDD laptops make similar sounds when they work, but they don't always exist. If there is a continuous and loud sound, you should go to a maintenance point to check if there is a problem with the hard drive.

2. Interference sound from the speaker. Check if there are strong magnetic objects around, sometimes it hiss when you don't hit ** in front of the computer.

3. Fan sound. This sound is usually emitted if the fan touches the internal circuitry, or when it touches the heat dissipating tin foil. If you don't know much about the computer in this situation, don't turn it on without permission, because if you want to remove the heatsink, you basically need to disassemble the C side of the notebook, and if you open it, it can be easily damaged.

The reasons why the computer has an electric current sound and the solutions are as follows:

1. The problem of power socket is that the static electricity cannot be eliminated due to the power socket not being connected, resulting in current sound.

Specific solution: First of all, it is recommended to unplug the external power supply to determine whether there is a power socket problem. If it is a socket problem, it is recommended to replace the socket and contact a professional to check the socket wiring as soon as possible.

2. The sound of the turntable of the mechanical hard disk or the sound of the CPU running at full load.

Specific solution: Reboot the computer and check the CPU.

The power supply of the computer will produce a slight sound of electric current.

The step-down circuit in the power supply will have a relatively large current, and the large current flowing through the conductor will cause the conductor molecules to collide, which is the often heard current sound state.

If the current sound is louder than the fan sound, it means that the power supply is about to be damaged, and it is recommended to replace it.

Normal. In most cases, the sizzling sound emitted by the computer's power supply is not an anomaly, but a normal operation sound.

Computers with tinnitus-like electrical sounds are generally mostly caused by power socket problems.

Static electricity cannot be eliminated due to the power outlet not being connected, resulting in the sound of electric current. It could also be the sound of a turntable on a hard drive, or a sound when the CPU is running at full load. First of all, it is recommended to unplug the external power supply to determine whether there is a problem with the power socket.

If it is a socket problem, it is recommended to try to replace the socket and contact a professional to check the socket wiring as soon as possible.

The computer has tinnitus like an electric current sound solution:

First, right-click on the speaker icon in the bottom right corner and select Devices. In the sound console that pops up, right-click on the device and select Properties in the menu. Note that some computers have more than one output device, just select the one you are connecting to (with a green tick icon on the device).

In the pop-up page, switch the tab to the Level tab. Note that if you don't have a driver for the sound card installed, and just rely on the system's built-in sound card driver, then you can't find the microphone option to be modified next in the pop-up control page. After the driver is installed correctly, there will be an additional microphone in the level column, pull the slider to the far left and click OK to exit.

The computer will not emit the sound of electricity. <>

It could be due to several reasons:

The card is not properly inserted, and the sound card is not tightly integrated with the expansion slot of the motherboard, and it can be seen that the "gold finger" on the sound card and the reed of the expansion slot are misaligned. This phenomenon is common on ISA cards or PCI cards, and it is a common fault, and finding a way to get the sound card plugged in can solve the problem.

The active speaker input is connected to the speaker output of the sound card, and the active speaker should be connected to the line-out end of the sound card, and the signal it outputs is not amplified by the sound card, and the noise is much smaller. Some sound cards have only one output, whether it is line-out or speaker depends on the jumper on the card, the default method is often speaker, so if necessary, you have to unplug the sound card to adjust the jumper.

The installed version of the sound card driver is not good, you may be using the driver that comes with the system, if so, it is best to install a special sound card driver. If you have installed the drivers that come with Windows, you can select "Control Panel System Device Manager Sound, ** and Game Controller", click on each sub-device, and select "Properties Driver Change Driver Install from Disk". Insert the disk or disc that came with your sound card and install the manufacturer's drivers.
