Chattering in the headphones. How to remove noise, interference or crackling in your headphones

Headphones are very simple devices, and, as a rule, they are reliably protected from various sound distortions. But, like any other acoustic devices, under the influence of various factors, they can wheeze, creak, phonate - the sound can deteriorate in different ways, but the essence is always the same. This can both spoil the impression of the sound of the headphones, and even make listening to music with their help impossible. What to do if the sound in the headphones is distorted in one way or another?

Why can headphones flicker?

The background in the speakers, whether they are headphones or emitters of any other acoustic device, is usually caused by physical impact on the device. In the case of speakers, the background can be caused, for example, by an amplifier if it is connected incorrectly, or even by neighboring speakers.

Very often, the speakers begin to flicker if a call is received on the phone lying next to them. Everyone knows this unpleasant high-pitched squeak and buzz - if this is the reason in your case, just move the phone away from the headphones and the background will disappear.

In addition to being affected by other electronics, hum can be caused by poor wire shielding. In this case, the background appears when the wire of the headphones or the connector to which they are connected comes into contact with metal. Most often, this situation manifests itself when headphones are connected to the line output on the front panel of a personal computer. This output is connected to the motherboard using very flimsy wires, which are affected by the metal case of the system unit, which leads to a background in the headphones. To get rid of the buzz, just move these wiring. But this will not completely solve the problem - in order for the background to no longer appear, you either need to glue the case with aluminum foil from the inside, or simply connect the headphones to another connector - for example, on speakers or on the back of the computer.

Another possible problem that causes a background in the headphones is a breakdown of the sound card or a malfunction in its drivers. If the board is broken, you will have to replace it or repair it at a service center. Drivers can be replaced by yourself. To do this, you need to find out the model of the sound card in the device manager, which is available in the properties menu of a computer running the Windows operating system. After that, you need to go to the website of the sound card manufacturer and download the necessary software.

Background in headphones when connected to the phone

If the headphones are not connected to a computer, but to a mobile phone, the background may be caused by a mismatch between the headphone plug and the smartphone jack. The fact is that headphones manufactured before 2011 and after 2011 have a different order of contacts on the plug.

The TRS (tip, ring, sleeve) plug used in headphones and headsets for mobile phones has four pins, two of which are used for sound output, the third for microphone sound input, and the fourth for ground. In headphones manufactured after 2011, the order of connecting the contacts has changed - the ground and the microphone have changed places. Accordingly, the connector in the phones has also changed. Therefore, when connecting old headphones to a modern phone, or vice versa, the connection may not work correctly, which leads to the appearance of a background in the speakers - the device is not grounded as it should.

Causes of Other Audio Distortions

The background is not the most common, although the most unpleasant of the possible sound distortions produced by the dynamic emitters of headphones. Much more often, the sound simply becomes quieter, then louder, wheezing, creaking. This can manifest itself both in any conditions, and only at certain frequencies, at a certain volume, or when connected to a specific sound source. The reasons for this behavior of the headphones, respectively, can be very different.

Before understanding possible breakdowns, it is worth excluding the simplest options. So, the sound can be distorted in a situation in which headphones are usually used because of their indispensability - namely, when listening to the radio from the phone. In this case, the headphones play the role of an antenna, so the FM receiver simply does not work without them. If the sound is distorted in this particular situation, the reason is most likely not in the headphones themselves, but in the radio - either the radio is faulty, or the place where you are has poor reception.

But this is a very special case. In the general case, the headphones creak and wheeze, usually due to mechanical impact on the plug and wires of the device. In order for the headphones to work properly and the sound in them to be clear, the wire must be solid, and its ends must be securely connected to the contacts on the plug and on the speaker. Thus, the design of the headphones is very simple, but often fragile - careless handling of the device and regular mechanical impact on it, especially at the points of contact of the wire with other parts, leads to the fact that the cable frays, loses insulation, which causes distortion sound.

All causes of wheezing and squeaking in one way or another boil down to cable damage. This can happen in three areas:

• at the junction of wires with a dynamic emitter;
• in one of the places along the entire length of the cable;
• at the point of connection of the wire to the plug.

Due to the loss of insulation, the wires carrying the signal for different channels affect each other, which leads to sound distortion. If the wire moves away from the contacts, the sound will first begin to deteriorate, and then completely disappear, so the cause of wheezing must be eliminated immediately after detection so that the headphones do not break completely.

Cable repair

Unlike a break in copper strands, which can be calculated with a multimeter, the weakening of wire insulation is not so easy to detect. To do this, you will have to carefully examine every millimeter of the cable length, twisting it in all directions until the sound is no longer distorted. When you find a place where the sound becomes clear again, the damage can be fixed. It is not necessary to cut the wire in this case.

In the intended place, using a sharp clerical knife, the cable sheath is peeled off. Under it you will find three wires - two of them conduct a signal to the speakers, the third one grounds the device. All of them must be separated from each other. To repair the damaged insulation, it is enough to wrap each of the wires with electrical tape, and then close the repair site with heat shrink tape.

Plug repair

Audio distortion can be caused by two plug problems:

• departure of wires from contacts;
• contact of individual wires with each other.

In any case, it will be easiest to replace the plug. To do this, the old part is cut off, the cable is stripped from the winding and insulation. After that, the bare cores are soldered to the corresponding contacts at the base of the new plug and are reliably isolated from each other.

Speaker repair

This operation is not so simple and is possible only if the headphone housing is easily disassembled - if disassembly of the plastic speaker housing is not provided, the repair simply does not make sense - even if the sound improves, it will still be impossible to use the headphones.

If there are screws on the headphone case that fasten individual parts, and you can disassemble it, do it. The copper cores of the cable should be attached to the emitter - if one of them is not held securely, solder it. Contacts must be insulated.

Thus, it is possible to correct sound distortion, but it is not always easy. Before attempting to repair the headphones, make sure that the problem is in them and not in other equipment.

Despite the ease of operation, sometimes we still encounter certain problems, such as extraneous sounds like hissing and wheezing, due to which the overall sound quality deteriorates significantly. To fix this problem, you need to know the possible causes of its occurrence.

It is important to know that, despite the elementary nature of this device, a person who has not previously encountered problems in his work and eliminate them, this problem may seem very serious.

In order to understand where the hiss in the headphones comes from, you need to understand at least a little how they are arranged. Pay attention to whether you hear hissing sounds constantly or only intermittently.

One of the reasons why this problem may occur is the incorrect connection of the headphones, or rather, the selection of the wrong settings. In addition, if the headphones are not new, check if the contacts with which you connect them are working.

Noises in the headphones caused by a malfunctioning sound card

Such a detail as a sound card has the most direct impact on how well the melody is reproduced by the equipment. If the part is defective, the personal computer cannot accurately transmit audio signals, which is why the normal sound is complemented by hissing, crackling, the sound seems to “break” and “jump”. In this situation, only the replacement of a defective part will help, and then the sound will no longer be accompanied by extraneous noise.

Faulty wires

The manufacturer of the model is often responsible for the correct operation of the headphones and the correct transmission of sounds.

You should know that there are two types of headphones: wireless and wired. Extraneous sounds, as a rule, appear in models that work through a cable connected with a plug. If the copper strand of the cable is damaged or stretched, noise interference and intermittent sound breaks will occur.

A damaged wire often leads to noise in the headphones on the iPhone. This is due to the fact that the material of the cable is thin and flexible, it breaks easily. A damaged conductor sends incorrect signal characteristics to the sound card, and this is reflected in the sound. How to eliminate wheezing headphones? This can be done by removing a torn or bare section of the wire, in extreme cases, you will have to buy new fittings.

Broken USB input

Incorrect sound may occur after connecting other gadgets to the USB connector. A mouse, or a faulty keyboard, can cause the problem. In this case, pressing the key, you will hear clicks. There are quite objective reasons why this happens.

When information is transmitted, the load on the PC increases. To reduce it, you need to do the following:

1. Switch the plug to another port.

2. You can also purchase a splitter and fix the old connectors to connect.

3. Start using wireless devices.

The problem is that very often users do not pay due attention to the computer, they do not immediately repair the problems that have appeared. As a result, USB connectors become unusable one after another, and only one remains, into which a splitter is connected, and it is on it that the entire load falls, which causes its increase.

How to wear in-ear headphones correctly

Mouse noise

When you scroll the page with the mouse, sometimes you can also notice noises, sometimes they are just unbearable. The solution to the problem is to replace the mouse, switch the mouse to a nearby USB port, or install an external sound card.

Lack of grounding sockets

This problem is not often, but still occurs, interfering with the normal operation of the headphones. Lack of grounding can also cause pops, clicks and other noises in the headphones. If you have already checked your headphones and found no problems, also check the outlets that your computer is connected to.

This nuance applies only to desktop computers, laptop boards are usually grounded at the stage of their production.

When you use headphones connected to a laptop, incorrect sounds are most likely caused by internal device malfunctions. Do not delay contacting the service center, where your device will be diagnosed for problems.

The sound source itself does not work correctly

Violation of the rules for using headphones often leads to a violation of their work, and in particular to the sound. Also, problems arise in the operation of the main sound source. Rarely, but still, driver errors occur. Program errors and failures in the operation of the operating system cause interference in the form of noise and crackling.

The problem can be detected by checking the device by connecting various headsets. If their work is equally unacceptable - unpleasant sounds will be heard in all headphones, then the problem lies precisely in the device driver.

If you are used to listening to music at a very high volume, you may also notice the appearance of hiss and crackling. As a rule, this happens if you purchase inexpensive headphones.

Insufficiently powerful power supply is another reason for extraneous noise when headphones sound (this problem sometimes occurs with laptop owners who have not yet figured out all its features). Fixing this issue is easy with the following tips.

On your laptop, go to "Control Panel", then to "System and Security" and finally to "Power Options", and select the "High Performance" mode. After completing the setup, check the sound quality in the headphones.

It is almost impossible to imagine the operation of a computer without sound. This is especially true for entertainment, video games without sound are not interesting, watching movies with subtitles also makes no sense, and listening to music becomes impossible. The sound is necessary, so each user has a speaker or several, or headphones. These devices are necessary, but no one wants to fork out for expensive options, people buy cheap audio systems that eventually fail or start to act up. What can I say, crackling in computer speakers and other extraneous sounds can appear even in expensive devices.

Noise may appear due to the operation of the computer, the operating system is loaded, information is being processed, all this is accompanied by unpleasant crackles and squeaks. Fortunately, the problem is solvable, but first you need to find out what is the reason for the appearance of extra sounds.

Throwing away the old device and buying a new one is the last resort. In fact, noise in headphones or speakers can appear due to damage or improper connection of wires, drivers, and even Windows settings.

PROBLEMS WITH CONNECTION CORDS

Often the hissing sound appears when the PC sound card and the device for sound reproduction are poorly connected. There are three options here:

• The connection wire is damaged. This causes not only interference in the computer speakers, but also such a problem when only one of the speakers works. It is not always possible to determine the location of the cord failure by eye, so it is better to connect the device to another computer and check.
• The contact between the sound device wire and the network card is of poor quality.

• The wire is not fixed. When a draft wags the cord, or children play with the wires, noise is generated in the speakers. In such a situation, it is necessary to attach the wire to a solid base; adhesive tape is suitable for this purpose.

It also happens that the problem appears due to the use of a long cord, while the crackling is not strong, but it still causes inconvenience. Using a shorter wire will solve the problem.

FAULTS DUE TO DRIVERS

The operation of the computer, including sound reproduction, depends on the drivers. When they are not installed, the user will not hear anything at all, and if a person downloads the wrong driver, then the device will be disrupted.

Such malfunctions appear after updating the "firewood" or installing a new package. This issue is reported by Windows.

To check whether these sounds in the headphones really appeared due to the drivers, we do the following manipulations:

• We go to the “Control Panel”, there we already click on the “Hardware and Sound” icon and click on the line “Task Manager”;

• If there is no yellow or red warning icon, then there is no problem with the sound drivers. When such signs are present, we fix the problems.

In any case, with available updates, you should do this. Perhaps the outside noise will disappear.

SETTINGS AND CONFIGURATIONS

Two or three randomly placed marks next to unknown options may degrade the sound quality. Hiss in the headphones appears when PCBeep is running and the line input is running. Other functions, depending on the settings of the computer, can also affect the volume and quality.

fig.1. Go to the "Control Panel" menu, select the "Hardware and Sound" icon, and then click on the "Volume Adjustment" function

fig.2. At the second stage of work, click LMB on the "Speakers and Headphones" icon

fig.3. The Levels menu has PcBeep settings, CD, etc.

• We translate all these functions to 0, save the configurations and check if this solved the problem.

In some situations, such simple manipulations really improve the quality of reproduction.

OTHER REASONS

QUALITY OF THE DEVICE

Extraneous noise appears in the speakers when the volume is increased. When this figure exceeds 50%, then noises, cods and other unpleasant effects appear instead of music.

This problem torments all owners of inexpensive devices, this is also called the "jitter" effect. Also, noises appear when the volume level of the speakers is set to the maximum, and in the operating system, on the contrary, at the minimum configurations.

In such a situation, we find the "golden mean"

To solve the problem with "jitter" when increasing the volume is almost impossible. The only way out is to buy new speakers.

WEAK SOUND CARD

In most computers, this part is installed directly into the motherboard and it is bought all together. Buying a separate card costs money and is not a popular decision.

The increased frequencies of all kinds of boards form electromagnetic actions that do not interfere with the operation of the digital part of the device, but strongly affect the analog components, which is why the quality of reproduction decreases.

Inexpensive PCI options are slightly better in this regard, but they also have this problem.

INCORRECT POSITIONING OF PARTS

When the board is installed near the video card, the computer speakers begin to make noise. The fact is that the video card produces special signals that come to the sound card and form noise.

If this is not possible, then we create a special reflective screen from cardboard and foil.

NO GROUND

Therefore, a computer connected to a regular outlet will produce sound with noise and crackles. In laptops, this problem cannot be solved, because in such a situation the board will not be grounded.

Extraneous sound and noise in the headphones and speakers must be eliminated.

Work and entertainment at the computer cannot be considered complete if there is no sound on it. It is necessary to watch movies, listen to music, receive notifications of new messages, and so on. You can name hundreds of programs, sites, games and applications that lose their relevance without sound.

The sound should be clear and loud, and its distortion is a big problem that every Windows 10 user can face. If the sound on the computer began to crackle, wheeze, muffled, hiss, or there are other problems with it, you need to fix the problem as soon as possible. malfunction. In this article, we will look at the main reasons why such sound problems can occur in Windows 10, as well as how to fix them.

Important: Before attempting to fix a software problem, make sure that the problem is not hardware. If the sound hisses from the speakers connected to the computer or laptop, try to check them by connecting the speaker system to the player or phone. In a situation where the laptop's built-in speakers wheeze, on the contrary, connect an external speaker system to your laptop and see how it will sound. You can also try disconnecting the laptop or computer connector from the sound card and plugging it back in.

Wheezing sound on the computer due to effects

The most common problem that most often leads to sound distortion is the included effects. In the Windows operating system, you can apply various effects to the output sound, which many users forget about, and they think that there are problems with the audio.

Sound effects on the computer may turn on due to changes in system settings by various applications that have administrator rights. You can check if the wheezing, hiss, or muffled sound is related to Windows effects in the audio settings. This is done as follows:

After saving the changes, make sure that the sound on the computer has returned to normal and has become “clean”. If it continues to crackle, wheeze, hiss or have other defects, go to the next step in the instructions.

Hissing and crackling sound in exclusive mode

Some versions of Windows 10 may conflict with sound card drivers, causing the user to experience defects when listening to audio in exclusive mode. Also, problems with exclusive sound mode can occur on a weak computer. To eliminate the possibility of crackling, hissing and wheezing when playing sound due to exclusive mode, we recommend that you try turning it off.

To prevent apps from using exclusive sound mode, right-click the speaker icon again in the notification area and select Playback Devices. Go to the properties of the device you are using and on the "Advanced" tab, uncheck both items located in the "Exclusive mode" section.

Check if the sound is corrected after disabling the burst mode.

Sound problems due to incorrect drivers

The Windows 10 operating system automatically installs the optimal (according to its version) drivers when the system is first started. However, in some cases, problems may arise with such drivers. To exclude this, it is recommended to download and install the latest version of drivers for the sound card on the computer from the official website of its developers.

Please note: If the problem with hissing, wheezing and other sound defects occurs on a laptop, you can also try reinstalling the audio drivers from the official website of the laptop manufacturer.

Important: If the Device Manager does not show that there are problems with the sound card drivers, this does not mean anything at all. Even in this case, it is recommended to try updating the drivers, since the system may not see the presence of defects in the sound, assuming that since the sound is output, then there is no problem with it, but in reality it may be different.

Quiet sound in Windows 10 due to communication settings

Another innovation of modern versions of Windows is the automatic muting of the sound output by various programs when calling, for example, in Skype. There may be situations when this option does not work correctly and, due to some errors, constantly keeps the sound muffled, believing that the computer is in ring mode.

To rule out the possibility of quiet sound problems due to this Windows feature, you can try disabling it and see if the problem persists. The option in the sound settings is disabled:

Note that this method helps to solve the problem only if the sound is quiet, but in a situation where it wheezes or crackles, the malfunction cannot be fixed.

Sound problems in Windows 10 due to incorrect playback format

Modern models of sound cards support almost any audio playback format that can be offered by the Windows operating system. However, if an old card is installed in the computer, this may cause problems.

To go to the playback format settings, you need to go to the "Control Panel" and select "Sound" from the available options. Next, click on playback device properties. A window will open where you need to go to the "Advanced" tab. Set the Default Format to 16-bit 44100 Hz (CD) and save your changes.

It is worth noting that the 16-bit format at 44100 Hz is supported by almost all sound cards, and it has been used since the early versions of Windows.

If none of the above tips helped to fix the situation with wheezing, crackling and hissing sound, we recommend that you try to scan your computer for viruses. It often turns out that the computer is infected with a Trojan or Malware virus, due to which the operating system “freezes”, which is accompanied by a temporary loss, wheezing or crackling sound.

Question from user

Hello.

I have a problem with the PC: there is some extraneous noise coming from the speakers and headphones (resembles crackling). I poked the wires - it did not help; also rearranged the inputs - the problem did not go away. By the way, if you click the mouse - then this noise is slightly amplified. What to do?

Built-in sound card, Realtek (I don't know the exact model). The headphones are new, the speakers are the most ordinary, although they are already quite old (7-8 years old).

Good day!

In general, there can be a great variety of noises found in speakers and headphones: for example, the noise of a mouse wheel, various crackling, whistling, intermittent and trembling noises, etc. They can appear for a variety of reasons.

The user problem with sound described above is quite typical (unfortunately), and it is far from always so easy and quick to fix it. Nevertheless, in this article I will try to give all the most important points that you need to pay attention to in the first place. By eliminating them, with a high degree of probability, you will make your sound better and cleaner.

If you have too quiet sound- try the tips from the following article:

If you have no sound at all on a computer - I recommend that you read this guide:

Causes and elimination of extraneous sound in speakers and headphones

Speaker/headphone cable

1) Is the cable intact?

Many do not attach any importance to this (allegedly, what will happen to it), and the cable, by the way, can be damaged by accident: when the furniture is carelessly moved, bent over, stepping on the heel. In addition, many people have pets at home. In general, there are enough reasons even without your direct intervention ...

The photo below shows a damaged audio cable...

2) Broken audio jacks

Over time, any audio connectors begin to "weaken" (most often from intensive use) - and the plug in them is not clamped tightly, sometimes there is even a slight backlash (gap). If in this case you try to insert / remove the plug, twist it in the socket - you may notice how noise appears in the speakers and how they disappear. Thus, you can choose the position of the plug, in which there will be no noise. The cable in this "ideal" position can be fixed with tape.

In general, if the problem is with broken sockets, replace them in the computer. service, the question is not too "expensive".

3) Cable length

I also want to pay attention to the length of the cable. If computer speakers are located 2 meters from the system unit, then using cables 10 meters long is unreasonable (especially if there are any adapters, extension cords). All this can cause "distorted" sound, a kind of interference. In general, cables longer than 2-5 meters (in the most common situations, for household use) are not recommended.

4) Is the cable fixed

Another reason I had to face was the following: the cable from the system unit to the speakers was on the "weight", about 2 meters long. Naturally, if the window in the room was open, then the draft made this cable "dangle" and extraneous noises were observed.

It was very easy to get rid of the problem: using ordinary adhesive tape, we attached the cable in 2-3 places to the table and the noise disappeared.

By the way, the cable can also be touched by passing people (if your PC is not very comfortable), pets, even your own legs (if the cable runs under the table). Therefore, my advice is: fix (fix) or lay the cable so that no one touches it accidentally.

The photo below shows special holders / clamps that exclude the "entanglement" of cables and exclude that some wires "will" hang out. These Velcro holders can be placed on the back of the table and secure all the wires and cables. Instead of them, by the way, you can use ordinary tape.

5) Front and rear audio jacks

Another important point: if laptops have only one audio connector (usually on the side panel), then the system unit has 2 of them (most often): on the back of the unit, and in front.

Many users find it more convenient to connect headphones (sometimes speakers) to the front of the unit - and often in this case the sound is not as good as if you connected it to the audio jacks on the back of the system unit. This is due to adapters, extension cords, etc. moments with connecting the front panel (from the back of the system unit - the audio outputs go "directly" from the sound card).

In general, the motive for this advice is simple: try connecting headphones / speakers to the audio outputs on the back of the system unit.

6) Is the cable intertwined with other cords

Also, extraneous noise may appear in the speakers due to the fact that the audio cable will be too "tightly" intertwined with other wires. Try to carefully position it so that it is away from the rest. By the way, this advice intersects with fixing the cable (see just above).

And one more tip: if you have hiss and noise in the speakers, try connecting headphones instead (or vice versa). This will not solve the problem, but will help find and diagnose the cause. If there is no noise in the headphones, then for sure the reason lies outside the system unit (which is already something ...).

Incorrect sound settings in Windows

Often, extraneous noise in the speakers is associated with not quite "correct" sound settings in Windows. Therefore, I recommend trying to change them ...

To do this, open the Windows Control Panel at: Control Panel\Hardware and Sound .

It will display several of your audio devices. Open the properties of the one through which the sound goes by default (such a device is marked with a green checkmark).

Note: by the way, if the default device for sound playback is not selected correctly, then you will not hear sound.

When will you open speaker properties(default playback devices) - look at the "Levels" tab (see screenshot below). In this tab, reduce all extraneous sources to a minimum: PC Beer, CD, Microphone, Line-in, etc. (their number and availability depends on your computer configuration).

Next, I recommend opening the tab "improvements" and see if it's enabled "Loudness" (by the way, in some versions of Windows it is called as " Additional features / volume leveling").

Save the settings and check if the sound has changed, if it has become clearer.

Lack of an up-to-date sound driver/driver setup

In general, usually, with problems with drivers - there is no sound at all. But modern versions of Windows (8, 8.1, 10) install drivers automatically. There is nothing wrong with this, on the contrary, they make life easier for novice users. But there is one big "BUT" - the drivers installed by them, usually, cannot be configured; there is no extra. panels where important parameters for your equipment are set. As a result, some sound distortion may occur.

In order not to repeat how to check if there is an audio driver in the system, how to find and update it, how to remove the old driver, etc. - I recommend to read this article:

You may also need programs to automatically update drivers in the system. I talked about them in this article:

I also recommend that you pay attention to the configuration of the driver itself. To open the audio driver settings: go to the Windows control panel in the section "Hardware and Sound" . Further at the bottom of the window, usually, there is always a link to the setting: in my case, this is Dell Audio (in yours, for example, it could be Realtek Audio).

In the audio driver settings, check the volume of the main devices ("play around" with it), disable various "incomprehensible" enhancements, filters, etc. Very often they cause all kinds of problems with sound.

Testing speakers on another PC

If the above recommendations did not work, I highly recommend connecting your speakers or headphones to another device: laptop, TV, PC, etc. You need to do this in order to determine the source of extraneous sound:

- either the speakers are "to blame" (if the sound is noisy on other devices);

- either the system unit itself is "to blame" (if the speakers behave normally when connected to other sound sources).

The reason may be grounding ...

Grounding (sometimes called grounding) in ordinary residential buildings, most often, they do it in the basement. All outlets in the building are connected to this ground. If all equipment (including speakers) is connected to the same outlet, then problems with interference due to grounding usually never arise.

If the noise is caused by grounding, then the easiest way to get rid of this is to connect all the equipment to the network through one common network outlet. Even better, if a surge protector (not Chinese, but normal quality, or UPS) is connected to the outlet, to which a PC and speakers will be connected.

The photo below shows a surge protector for 5 outlets. Enough for most ordinary home PCs, you can connect: a monitor, a system unit, speakers, a printer, and even a phone charger will remain ...

Important! In the absence of grounding, some authors recommend connecting the system unit case to a conventional battery. I do not recommend doing this categorically (with a certain network construction - you can be shocked)! In general, the issue of grounding is best dealt with by an electrician.

Mouse wheel noise

Sometimes the noise from scrolling the wheel from the mouse "falls" into the audio interference and is heard in the speakers. Sometimes such noise can be quite strong and it is simply impossible to listen to music while working.

If the sound from the mouse is heard in the speakers, then I recommend taking the following series of measures:

Try to replace the mouse with a new one;

If you are using a mouse with a PS/2 connector, replace it with a USB one (or vice versa);

You can also use PS/2 to USB adapters. For example, by connecting a mouse with a PS / 2 connector to a USB port;

Try using a wireless mouse.

The photo below shows: a mouse with a PS / 2 plug, a USB mouse, and adapters from PS / 2 to USB.

Mobile phones and gadgets

If your mobile phone is too close to the speakers, then when you call it (or receive SMS), you can hear a strong crackle and interference. You can, of course, try to shield the audio cable, but at home, in my opinion, all this is a waste of money, time and effort.

The best way out is to find a place for a mobile phone not on a computer table, or at least smash the phone and speakers in different corners. Thanks to this, crackling and noise will be significantly reduced.

By the way, this can be observed from walkie-talkies, cordless phones and other similar gadgets and set-top boxes. Anything with an antenna and radio signals can potentially be the source of the strongest vibrations reflected in your speakers.

In some cases, even an ordinary printer/scanner/copier, an "unusual" table lamp can cause noise in the speakers. Therefore, at least for the time of diagnosis, I recommend turning off foreign devices that are near the speakers one by one and monitoring the condition and purity of the sound.

I don't think there's anything more to comment on...

High volume on low-quality speakers

Loudness above 50% on inexpensive low-quality speakers (and headphones) may well be the cause of the noise. (they say that the speakers start to "flash").

In general, all the speakers and headphones are phoning. True, better speakers (and, as a rule, more expensive ones) produce a clearer sound even at high volumes, and only emit light at maximum. While cheap - when the volume reaches the average values ​​...

Also pay attention to the microphone. If your speakers are turned on loudly and the microphone is working, then the effect of a closed "ring" may be observed.

Low Power (Eco Mode)

This advice is more suitable for laptop users...

The fact is that laptops have several operating modes: economical mode, balanced, and high performance. Manufacturers do this in order to save battery power more economically.

In some cases, reduced power consumption does not allow you to produce high-quality sound. Therefore, I recommend going to the Windows control panel: Control Panel\Hardware and Sound\Power Options . Then enable high performance and save the settings (see screenshot below).

Installing an external sound card

For some reason, many people think that an external sound card is some kind of large device, expensive, etc. All this is in the past, now there are modern sound cards, the size of which is slightly larger than a USB flash drive (and they look almost the same).

Yes, you can't connect any specific equipment to such a sound card, but you can connect ordinary classic headphones and speakers, a microphone to it, which is more than enough for many "average" users.

In addition, an external sound card can simply help out and help get rid of extraneous noise when other options did not solve the problem. Moreover, the cost of many models is more than affordable (the cheapest options cost no more than a few hundred rubles).

The photo below shows a USB sound card. Such a small "baby" is capable of producing a fairly high-quality sound, which will be envied by some of the built-in sound cards. And in principle, it will suit most users, who will be satisfied with the most "ordinary" sound.

That's all for me. Additions on the topic are welcome...
