Background noise in headphones from the computer. How to remove noise, interference or crackling from headphones. Why does noise occur when using headphones?

09.07.2021

Causes of noise in headphones:

You connected your headphones to your computer or laptop, and instead of pleasant and favorite music you hear annoying hissing or crackling, who would like that? At the same time, you don’t understand why there is noise in the headphones, where it came from and what to do about it.

The most annoying thing about the noise effect in headphones is that it is very difficult to figure out what caused it and how to eliminate it. There can be many reasons for crackling noise in headphones; the usual algorithm for finding the cause of poor performance of a headphone is to sequentially search through potential sources of noise, exclude or isolate them, and then check them further. In theory it looks simple, but in practice such an algorithm is impossible to fully implement.

For example, you have only one computer, which is connected to an outlet that is built into a concrete wall, the apartment has been renovated and it is impossible to install the computer in another place, or another room, because... there is no place for him. And therefore, we are unable to exclude all possible causes of extraneous noise in the headphones.

However, we can start with the simplest and most obvious potential causes of interference in headphones, and if checking them does not yield results, then we can only hope that this problem will correct itself in the future. For example, your neighbors will turn off the hammer drill, or after a while you will buy a voltage stabilizer through which you connect your computer.

So, let's start looking for the cause of hissing in headphones.

Cable damage is a very common cause of hissing and crackling in headphones.

Let's start with the simplest and most common cause of extraneous noise in headphones - a damaged cable or poor contact in the socket.

Carefully examine the headphone cable, it must be absolutely intact, and there must be the same density inside along its entire length. Feel the entire cable with your hands, perhaps there was a break somewhere inside the cable, or one day you bent the cable too much and the copper strands inside it broke.

If, after a visual and tactile check, the cable does not raise suspicions, check the jack, its joints and the audio jack itself into which you connect the headphones.

Check how well you insert the jack into the socket, it should go in easily, with a slight click and stay firmly in it. The jack must fit all the way into the socket; no visible part of the jack should remain.

Sometimes, due to the structural features of the nest, about 1 mm of the jack remains visible, but no more, and this is a rare phenomenon.

Poor contact is one of the most common causes of noise and crackling in headphones. Wipe the jack with a dry soft cloth; it may be dirty or covered with a layer of oxide.

If the wire does not cause suspicion and the jack is connected to the socket securely, but the noise remains, you need to continue the search.

The technical condition of the headphones is a possible cause of white noise

After checking the wire and jack did not produce results, you must check the headphones themselves.

Inspect them carefully; they may have recently fallen onto a hard surface, or cracks or other signs of damage may have appeared on the body.

Be sure to try connecting the headphones to another audio source, such as a phone, TV, or tablet.

It is very important to understand and establish that the cause of white noise in headphones is not the headphones themselves, but rather the device to which they are connected.

If, when connected to another device, the white noise disappears, it means that the headphones themselves are fine, along with the wire and jack, and we move on to further search for the origin of the crackling sound.

Inexpensive speakers may cause noise in headphones

If noise in the headphones occurs when connected to a computer or laptop that simultaneously has inexpensive multimedia speakers connected, first try turning off the speakers and checking if the noise in the headphones has disappeared.

The fact is that inexpensive speakers are assembled from cheap elements, but the most important thing is that when assembling them, they save a lot on soldering, wires and the general level of construction. Therefore, poor contacts or short circuits may occur inside the speakers, which will interfere with the entire electrical circuit, resulting in extraneous noise appearing in the headphones.

The speakers need to be turned off completely, and not just turned off.

If completely disconnecting the speakers from the computer does not help eliminate the noise in the headphones, proceed to the next troubleshooting step.

Lack of grounding is the most common cause of noise in headphones when connected to a computer.

For some reason unknown to me, many homes do not have electrical outlets grounded. In general, this is not so bad; traditional household appliances such as irons, heaters, filters and air conditioners work normally. But as soon as you connect equipment that is very sensitive to the quality of the power supply to an ungrounded electrical network, problems immediately arise.

A computer connected to an ungrounded outlet is a direct path not only to noise in the headphones, but also to a possible reason for the failure of the entire computer due to exposure to static electricity.

The normal way to solve this problem is to ground the outlet to which the computer is connected. But doing this on your own is not easy, if at all possible. To do this, you need to call an electrician, however, in this case, most likely, you will have to rewire the entire apartment, and this is a serious repair.

There is a simple way to check whether grounding will really help eliminate noise in the headphones - run a wire from the computer to the battery.

You need to take an ordinary copper wire of small cross-section, with bare contacts on both sides. Place one end against the computer case (preferably against the back wall), and the other against the battery. It is useless to lean the wire against the painted part of the battery; you need to lean it against the metal of the battery, so you will have to look for such a place. You can usually find bare metal on the back of the battery.

If you did everything correctly and the noise goes away or decreases significantly, then the problem is grounding.

Remember: grounding through the battery cannot be considered a permanent solution. Such grounding can lead to complete failure of the entire computer; all it takes is for your neighbor to ground serious equipment to the battery, and the computer, having received a powerful discharge of electricity to the case, will fail. This is just a way of checking, nothing more.

But what to do if you know for sure that the sockets are grounded, and checking with the wire did not give anything? We continue to search for crackling noise in the headphones.

Microphone noise is one of the many causes of interference in headphones

We have looked at the possible sources of the noise problem in headphones, which relate to material interference, but now we are left with problems that relate to the setup of computer equipment.

One of the most common causes of noise in headphones is noise from the sound card microphone.

Even if you don't have a microphone connected to your sound card, you may experience noise from the microphone jack.

In order to test this hypothesis, you need to go to the sound volume settings of your sound card, find the slider that adjusts the microphone volume level and reduce it to zero. Or, if possible, turn off the sound from the microphone altogether.

If the noise in the headphones was caused by the microphone input, then turning off the sound from it should completely correct the situation.

To get to the microphone volume settings, open the control panel, find the item "Equipment and Sound" and go into it.

Now find the item "Sound" and go into it.

In the sound settings window, go to the tab "Record", then find the active microphone (in my case it is the Sound Blaster ZxR microphone), select it and click on the button "Properties" in the lower right corner.

In the new window, find the tab "Levels", and either move the microphone volume slider all the way to the left until its value reaches zero, or click on the blue speaker icon, which is located to the right of the volume indicator. A red crossed out sign should appear next to the speaker. This icon will indicate that the microphone is completely muted on the system. It is preferable to turn it off, and not just lower the volume level.

One type of problem with the microphone input or the microphone itself is its high sensitivity. This problem can be solved by turning on the microphone noise reduction mode.

Almost all modern sound cards have this mode. If you find out that the reason for the crackling noise is the microphone, but you need it, then try turning on the noise reduction mode if it is available. This should solve the problem.

A problem with the volume level of sound sources in the sound card may cause hissing in headphones

Not only microphone interference can cause hissing in headphones, but adjacent sound card inputs can also cause the same interference.

Depending on the sound card model, it may have additional inputs for connecting additional equipment. They may have the following names:

What U Hear
Line in
S/PDIF

Any of them, under certain circumstances, can become a source of interference. Just like you turned down the microphone volume, you need to turn down or completely mute the volume from all of these jacks.

To do this, go to the Windows Control Panel.

Then find the item there "Equipment and Sound".

Then click on the section "Sound".

In the new window, go to the “Playback” tab, select the active speakers (the device that is currently playing sound in the headphones) and click on the “Property” button.

Next, I won’t be able to take a screenshot, because... in my case, the volume level of all inputs and outputs is controlled through special software that controls my Sound Blaster sound card; in your case, most likely, the tab will be available "Levels", by going into which you can disable all inputs and outputs of your sound card.

To test, leave only the headphone output turned on, and turn off all other possible outputs and inputs or reduce their volume to zero.

If the problem of headphone hissing was in one of these points, it should disappear.

Volume level is paradoxical, but true, it can cause interference in headphones

In some cases, the volume level may cause noise in the headphones.

Sometimes it happens that headphones have their own volume control, plus there is an additional volume control in Windows, and there is also a volume control in the application from which you are listening (game, player).

In order for any hardware that has its own hardware volume control to work well, it is necessary to ensure that all software volume controls (especially the main volume slider in Windows) are set to 100%. And the final volume adjustment is made using a hardware volume control.

To eliminate hissing, follow these steps:

Completely mute the sound in the headphones using a hardware control (buttons or knobs on the headphones themselves)
Set the volume in Windows to 100%
Set the volume in the application to 100%
Start by gradually increasing the volume on your headphones and bring it up to a comfortable level.

The fact is that software volume controls artificially reduce the sound volume, after which you have to turn the volume up to maximum in your headphones in order to listen to it at a comfortable level. However, for any equipment, be it headphones, speakers or a car engine, prolonged operation at the limit of the possible is extremely detrimental to the characteristics and properties of the unit.

When you set the hardware volume on your headphones to maximum, you are amplifying all the noise that comes from the computer, plus adding distortion that appears in the headphones themselves at maximum sound level.

Therefore, you need to adjust the volume using the method I indicated in order to minimize possible distortion and noise from the headphones themselves, as well as remove the artificial amplification of unwanted noise.

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

It is important to know that, despite all the elementary nature of this device, to a person who has not previously had to deal with problems in its operation and eliminate them, this problem may seem very serious.

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

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 whether the contacts with which you connect them are working properly.

Noise in headphones caused by faulty sound card

A detail such as a sound card has a direct impact on how well the melody is reproduced by the equipment. If a part is faulty, the personal computer cannot accurately transmit sound signals, which is why the normal sound is supplemented by hissing, crackling, and the sound seems to “break” and “jump.” In this situation, only replacing the faulty 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 operate via a cable connected with a plug. If the copper core of the cable is damaged or stretched, noise interference and intermittent interruptions in sound appear.

A damaged wire often leads to noise in the headphones on an iPhone. This is due to the fact that the cable material is thin and flexible, it breaks easily. A damaged conductor sends incorrect signal characteristics to the sound card, and this affects the sound. How to eliminate wheezing in headphones? This can be done by removing the torn or exposed 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. The problem could be caused by a mouse or a faulty keyboard. In this case, when you press a key, you will hear clicks. There are quite objective reasons why this happens.

When information is transferred, 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 repair the old connection sockets.

3. Start using wireless devices.

The problem is that very often users do not pay due attention to their computer and do not immediately repair problems that appear. As a result, the USB connectors one after another become unusable, 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 properly wear in-ear headphones

Mouse noise

When you scroll the page with your mouse, sometimes you may also notice noises, sometimes they are simply 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 of sockets

This problem is not common, but still occurs, interfering with the normal operation of the headphones. Lack of grounding can also cause crackling, clicking and other noise in the headphones. If you have already checked your headphones and found no problems, also check the outlets to which your computer is connected.

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

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

The sound source itself does not work correctly

Violating the rules for using headphones often leads to disruption of their operation, and in particular to the sound. Problems also arise in the operation of the main sound source. Rarely, driver errors still occur. Program errors and malfunctions in the operating system cause interference in the form of noise and crackling.

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

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

Insufficiently powerful power supply is another reason for extraneous noise in the sound of headphones (this problem sometimes occurs among laptop owners who have not yet figured out all its features). Fixing this problem is simple by using the following tips.

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

Connecting any device to a computer is a process that requires special attention. The more complex the peripheral component, the more complex the procedure. Quite often, headphones/speakers and microphones are connected to computers. These elements help you communicate online. It is very difficult to imagine a modern user without them.

On the one hand, connecting headphones and a microphone does not require anything special. Only after the idea has been brought to life, it often takes a long time to configure these components. They work with errors. Most often, users wonder how to remove noise from headphones on a computer. Why does he even appear? What will it take to fix the problem? And is it really possible to get rid of it? If you can answer all the questions asked, connecting a headset and working with sound on a PC will not cause any trouble.

Why is there noise?

Initially, it is important to understand where the noise in the headphones comes from. Many users face this problem. Sometimes this is a temporary phenomenon, in some cases the noise does not disappear for a long time.

In fact, the nature of the problem is varied. Noise in headphones (with or without a microphone) occurs for various reasons. It is problematic to predict which alignment will help correct the situation. For example, noise may be caused by hardware damage or misconfigurations. Next, you need to figure out how to get rid of noise on your computer.

Sound card

The first reason that can affect the sound quality in the operating system is that it is bad. If it is damaged or outdated, noise appears in the headphones.

The sound “breaks”; various crackling, squeaking and other noises may appear in the headphones or speakers. The situation can only be corrected by replacing or repairing the sound card. Only after that the headphones will disappear.

Grounding

The following problem occurs very rarely. We are talking about the lack of grounding at the sockets to which the headset and speakers/headphones in general are connected. In this case, various types of noise may appear.

If we are talking about a laptop, most likely, connecting the computer to a grounded outlet will not fix the problem. As a rule, in laptops it is the boards on the mother card that may not be grounded. You will either have to replace them or accept the problem. In some cases, users prefer not to use a particular laptop.

USB devices

Are there noises in your headphones on your computer? Usually, different kinds of sounds occur when connecting various devices. They appear immediately, not after some time.

For example, when connecting a mouse, you may hear a monotonous sound. And if we are talking about a keyboard, most likely you will hear clicks when you press the keys.

This happens due to:

Active transfer of information to the computer. Then it is recommended not to connect USB devices to certain ports. It is advisable to find other places. Or even start using a wireless headset and other devices.
Damage to the USB port. It is proposed to carry out repairs. In practice, users simply reconnect all devices to different ports.

Fortunately, this situation does not occur very often. Modern computers and laptops are made so that users can work on machines comfortably. Therefore, such a situation is unlikely to occur in practice.

Cable

How to remove noise from headphones on a computer? Much depends on what type of headset the user has. The thing is that now all devices are divided into wired and wireless. This feature plays an important role.

Often noise in speakers or headphones is found on models connected via cable. This is where the main problem lies. For example, when the cable from a microphone or headphones is damaged, various types of noise arise. This happens due to poor quality transmission of information to the sound card.

It is likely that the cable is damaged. Then the breakdown must be repaired. If wireless ones are used, this arrangement will not help.

Another trick that is advised to users with a wired headset is to remove the cord from the socket and reinsert it into the computer. This is the method that often helps get rid of noise.

Drivers

But the next source of the problem is relevant for all devices. But in practice it is rare. The thing is that strong noise in the headphones on the computer is a consequence of damage or lack of sound card or device driver.

In such a case, you simply need to reinstall or update the corresponding software package for normal operation of the operating system with the connected device. For wireless headphones, as a rule, the corresponding drivers are included in the kit on a separate disk. As a last resort, you can download them from the website of the sound card or headset manufacturer.

Maximum sound - problems guaranteed

Background noise in headphones of any model is often encountered when the sound settings are incorrectly set. It doesn't matter whether a microphone is connected to the PC or not. After all, in this situation, nothing depends on him.

If your audio settings are set to maximum, you may experience noise or wheezing on your computer. Users who bought cheap speakers or headsets suffer from a similar problem.

The fix is simple - by turning down the sound. For example, through a mixer in the operating system. You just need to click on the gramophone image (near the clock and date), then move the slider down. So that the noise disappears. Nothing difficult or special. This is why it is recommended to buy mid-priced headphones. They encounter this problem less often.

Microphone - benefit or harm

Now it’s clear how to remove noise from headphones on a computer. But these are not all the techniques that can help. What to do if all the previously listed scenarios did not work?

The presence of a microphone on a PC plays an important role. It is this that often becomes the source of noise in headphones. What to do?

It's clearly not worth giving up the microphone. Instead, you will have to make small adjustments to the sensitivity and volume of the device. Then you will be able to get rid of excess noise.

How to do it? You need to follow a few instructions. It looks something like this:

Boot your computer. Be sure to connect a headset with a microphone.
Right-click on the mixer on the right side of the screen. In the menu that appears, click on “Sound recording devices...”.
Find the connected microphone. Double click on the corresponding line.
Go to the "Levels" tab.
Adjust the microphone volume and sensitivity by moving the sliders. If there is PC Beep, turn it off (move the volume mark to zero).
In the "Improvements" section, check the box next to "Reduce noise level". You can also check the "Remove constant component" item.

All this will help to quickly get rid of the noise in the headset. How to set the microphone settings correctly? This is an individual component; each user independently selects the option that suits him.

Conclusions and Conclusions

It doesn't matter which headset is connected to the computer - wired or not. The main thing is that the majority of problems occur on all device models. for a computer with a microphone are most often connected and used without much difficulty. And the main cause of noise in the headset is the high sensitivity of the microphone, as well as the really loud environment around the user.

How to remove noise from headphones? All of the above methods will definitely help correct the situation. If we are talking about a wireless headset, then if there is constant noise, it is recommended to change the USB socket used as a receiver. Otherwise, all the previously listed tips remain the same.

Extraneous noise in headphones occasionally occurs due to virus infection. After curing the computer, the headset begins to work properly. Fortunately, these types of events are not that common. And the main methods of dealing with the problem under study are to reinstall the driver, reduce and adjust the microphone. From now on, it’s clear how to remove noise from headphones on a computer.

Question from a user

Hello.

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

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

Good day!

In general, there can be a great variety of noises encountered in speakers and headphones: for example, the noise of a mouse wheel, various crackling sounds, 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 not always so easy and quick to fix. However, in this article I will try to give all the most important points that you need to pay attention to first. By eliminating them, with a high degree of probability, you will make your sound better and cleaner.

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

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

Causes and elimination of extraneous sound in speakers and headphones

Cable for connecting speakers/headphones

1) Is the cable intact?

Many people don’t attach any importance to this (supposedly what will happen to it), and the cable, by the way, can be damaged accidentally: if you move the furniture carelessly, bend it, or step on your heel. In addition, many people have pets in their homes. In general, there are enough reasons without your direct intervention...

The photo below shows a damaged audio cable...

2) Broken audio connectors

Over time, any audio connectors begin to “weaken” (most often from intensive use) - and the plug is not clamped tightly into them, sometimes there is even a slight play (gap). If in this case you try to insert/remove the plug and twist it in the socket, you may notice how noise appears in the speakers and how they disappear. In this way, you can choose a position for the plug that will not produce noise. The cable can be secured with tape in this “ideal” position.

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 some adapters or extension cords). All this can cause “distorted” sound, a kind of interference. In general, I do not recommend using cables longer than 2-5 meters (in the most common situations, for household use).

4) Is the cable fixed?

Another reason that I had to deal with was the following: the cable from the system unit to the speakers was suspended, about 2 meters long. Naturally, if the window in the room was open, then the draft caused this cable to “dangle” and extraneous noise was observed.

Getting rid of the problem was very simple: using ordinary 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 convenient), pets, even your own legs (if the cable runs under the table). Therefore, my advice: secure (fix) or lay the cable so that no one accidentally touches it.

The photo below shows special holders/clamps that prevent the cables from getting tangled and prevent any wires from dangling. These Velcro holders can be placed at the back of the table and secure all the wires and cables. By the way, you can use regular tape instead.

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 side of the unit, and on the front.

Many users find it more convenient to connect headphones (sometimes speakers) to the front side of the unit - and often in this case the sound is not as high quality as if you connected it to the audio connectors on the back wall of the system unit. This is due to adapters, extension cords, and other issues 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 behind this advice is simple: try connecting headphones/speakers to the audio outputs on the back wall of the system unit.

6) Is the cable intertwined with other cords?

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

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

Incorrect sound settings in Windows

Often, extraneous noise in the speakers is associated with not entirely “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 device through which the default sound comes (such a device is marked with a green checkmark).

Note: by the way, if the default device for sound playback is selected incorrectly, 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 is enabled "Loudness of Compensation" (by the way, in some versions of Windows it is called " Additional features/volume equalization").

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

Lack of current sound driver/driver settings

In general, usually, when there are 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 they install usually cannot be configured, i.e. there is no extra panels where important parameters for your equipment are set. As a result, certain sound distortions may occur.

In order not to repeat myself about 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 reading this article:

You may also find programs for automatically updating drivers in your system useful. I talked about them in this article:

I also recommend paying attention to the settings of the driver itself. To open audio driver settings: go to the Windows Control Panel in the section "Equipment and Sound" . Further at the bottom of the window, there is usually always a link to the settings: in my case, this is "Dell Audio" (in yours, for example, this could be Realtek Audio).

In the audio driver settings, check the volume of the main devices (play around with it), disable various “obscure” enhancements, filters, etc. Very often they are the cause of all sorts of sound problems.

Checking speakers on another PC

If the above recommendations do not give any effect, I highly recommend connecting your speakers or headphones to another device: laptop, TV, PC, etc. This must be done in order to determine the source of extraneous sound:

- either it’s the speakers’ fault (if the sound on other devices is noisy);

- or 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 sockets 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 equipment to the network through one common power outlet. It’s even better if a surge protector (not Chinese, but standard quality, or UPS) is connected to the outlet, to which the 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 there’s also room for a phone charger...

Important! In the absence of grounding, some authors recommend connecting the system unit case to a regular battery. I categorically do not recommend doing this (if the network is built in a certain way, you may get an electric shock)! In general, the issue with grounding is best resolved with an electrician.

Noise from mouse wheel scrolling

Sometimes the noise from scrolling the mouse wheel gets 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 you hear sound from the mouse in the speakers, then I recommend taking the following series of measures:

Try replacing the mouse with a new one;

If you use 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 an SMS), you may hear a strong crackling sound 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 your mobile phone that is not on the computer desk, or at least place 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, radiotelephones and other similar gadgets and set-top boxes. Anything that has 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 or an “unusual” desk lamp can cause noise in the speakers. Therefore, at least for the duration of the diagnosis, I recommend turning off any extraneous devices located near the speakers one by one and monitoring the condition and purity of the sound.

I think there is nothing more to comment here...

High volume on low-quality speakers

Volume above 50% on inexpensive low-quality speakers (and headphones) may well be the cause of noise (they say that the speakers are starting to make noise).

In general, all speakers and headphones produce noise. True, higher-quality speakers (and, as a rule, more expensive ones) produce clearer sound even at high volumes, and only produce noise at maximum. While cheap ones - when the volume reaches medium levels...

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

Low power supply (Eco mode)

This tip is more suitable for laptop users...

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

In some cases, reduced power consumption does not allow for high-quality sound. Therefore, I recommend going to the Windows Control Panel: Control Panel\Hardware and Sound\Power Options . Then turn on 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 a thing of 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 cannot connect any specific equipment to such a sound card, but you can connect ordinary classic headphones and speakers, and 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 fairly high-quality sound, which will be the envy of some built-in sound cards. And in principle, it will suit most users who are satisfied with the most “ordinary” sound.

That's all I have. Additions on the topic are welcome...

Almost all home computers and laptops are used for work, participating in various gaming processes, traveling on social networks and other sites, and, of course, playing audio and video recordings.

For this reason, users have connected special speakers or headphones to most devices. These elements help improve the sound and increase its volume. In some cases, both of these components are used.

But when using speakers, not only necessary but also extraneous sounds may arise. These can be a variety of noises. Quite often, users encounter this kind of difficulty. But since this interferes with enjoying watching a movie or listening to your favorite musical composition, you need to try to understand this issue and eliminate it.

This question cannot be called simple, although at first glance this is exactly the impression that users get. In fact, the appearance of crackling, trembling, and various other noises is provoked by a variety of reasons.

But it is pointless to consider all the reasons, since this process is incredibly lengthy. So it’s worth focusing on the most common scenarios that provoke this problem.

But first, it’s worth checking the functionality of the speakers, headphones, and connectors into which these elements are connected. To do this, you should use a third-party device. You will need to connect these components to it. To check the connectors, you will need to connect other speakers and headphones to them. If this is all right, then it’s worth considering other possible reasons.

Checking for the necessary drivers

Extraneous sounds can appear in a variety of ways. But if they have already arisen, then it is imperative to understand that this problem cannot be eliminated on its own. So let's start finding the causes and quickly troubleshooting.

Anything can happen due to driver problems. Very often, users may note that the gadget is not functioning correctly because it is missing several drivers or they are outdated. The reason is trivial, but these components may cause the device to fail.

If special drivers are not installed, the sound may not be played at all. Incorrect operation is also noted in cases where completely incorrect drivers were installed. It is extremely important that only those elements that are 100% suitable for the gadget being used are loaded onto the device.

Otherwise, all kinds of program malfunctions will begin. The sound card will eventually not provide sound playback in the correct mode. In general, the operation of numerous elements that together ensure the reliable functioning of the device is disrupted.

This is why, in the end, various noises appear. Problems of this nature may accompany the process of reinstalling the operating system. That is, when the user boots into Windows or updates the system, difficulties arise with the drivers.

The user can learn about this from the corresponding notification that will be shown on the PC screen. To check whether the job is running correctly or not, you will need to go to the Task Manager. To do this, activate this assistant.

This can be done using several keys or by going to the Control Panel, which is located in the main menu on the desktop. Next, go to the equipment and sound section. And after that, several sections will appear, among which you can find the Task Manager.

After this, you will need to open a tab called “Audio Inputs and Audio Outputs”. Now you need to carefully look at whether yellow or red exclamation marks are indicated next to the devices. If none are visible, then the problem is not related to the drivers.

But if suddenly they are present, then the problem arose with these elements. In this case, you will need to check the presence of all necessary components. If necessary, all that remains is to load the missing objects. After this, there should be no more difficulties with sound. But this is only if the drivers were the culprits.

Difficulties with the cable. Common cause of noise

There are often cases when users have to deal with a cable that is not working properly. This is one of the most common reasons. As a result, extraneous sounds, noises, cracklings, etc. may appear.

The problem is poor contact between the speaker and the sound card. Contact deteriorates for a variety of reasons. Most often this happens because the cable may be loose. At the same time, it can move to different positions, becoming damaged.

So the best solution is to attach the cable to a wall or piece of furniture. In this case, it will always be in one position and not be damaged by people and animals.

There are also frequent cases of damage not to the entire cable, but to its individual parts. In this case, the sound may disappear not in two speakers, but in one. To verify this type of damage, you should install the headphones to another device. During testing, it will be possible to identify the true cause. This means that its consequences can be eliminated.

Poor contact may also be detected between the device’s network card socket and the plug of the headphones connected to it. Sometimes some manipulation of the plug may be a way out of the situation. You can try taking it out and then putting it back in again.

You can also try it a little and turn it very carefully. We turn it in any direction and check whether the connection is ensured or not. In some cases, these simple steps can help.

In any case, it is necessary to monitor exactly how the cable is placed. It should always be attached to the floor or wall. In this position it will be least damaged during use. Also, you should not move the cable every time, rotate it, or perform other manipulations that could harm the signals transmitted through it.

Also, difficulties often arise for other reasons. If this element is too long, then you should not be surprised by extraneous sounds. This is due to the fact that the cable often bends. In this position, it transmits a damaged signal. So you should make its length the optimal size and the problem will be eliminated.

Adjusting sound settings

Difficulties often arise precisely for this reason. It’s hard to even imagine that properly adjusting playback settings can improve sound quality. But if the user has performed the settings incorrectly, noise and other sounds may appear.

In this case, the user may not even realize that he previously performed some actions incorrectly. Quite often, various kinds of noise in the sound can be observed due to PC Beer and the line input being turned on. Often, incorrect settings provoke changes in frequency parameters.

This is subsequently reflected in the sound quality. In this aspect, it is necessary to take into account the characteristics of the device used, since for each device the settings are made individually. Sound data adjustments are made in the control panel.

Users will need to go to the sound and equipment section. Then open the tab with volume settings. Now an icon with a picture of a speaker will appear, which you will need to click on. In this case, the device properties will open, which are displayed as “Speakers and Headphones”.

Users should slightly reduce the signal level, as well as make some other adjustments regarding the PC Beer section. You need to look at the data that is specified in the CD parameters, as well as in the line-in tab.

As soon as the work is completed, it is imperative to save the entered information. In some cases, after this kind of manipulation, the reproduced sound becomes much “cleaner” and more beautiful. So don't neglect the settings.

Poor quality equipment

Some users prefer to buy inexpensive products, but still demand high quality from them. But this happens extremely rarely. Often, users notice a decrease in the quality of the reproduced sound.

The thing is that when creating inexpensive speakers and headphones, it is impossible to use expensive parts. Therefore, you should not demand anything supernatural from such components. Inexpensive models will not provide excellent sound. You should especially not set the volume level to the maximum, since in this case interference will be especially noticeable.

You should always adjust the volume level not only directly on the speakers, but also on the computer you are using. Only if harmony is achieved can good quality sound be achieved. In general, you shouldn't skimp if great sound is your goal.

Other reasons: grounding and power supply

This problem can occur if the speakers pass electrical signals through themselves. They also pass through the body of a personal computer. That is why you should not be surprised that various extraneous noises arise, which, in theory, should not exist.

To eliminate this problem, you will need to use an incredibly easy-to-implement technique. It consists of ensuring the connection between the device body and the battery. All this is done using a regular cable or cord. It is possible to eliminate interference in this way if the cause was directly related to grounding.

But difficulties can also arise due to the power supply. Since this problem only affects laptops, it does not affect users of desktop devices. So laptop users can try checking the sound card for power. If it is not enough, then this provokes the appearance of third-party noise.

You can check this in the power supply tab. You can find it in the main menu. Click on the “Start” button, after which many sections will appear, among which the Control Panel will certainly appear. Next we find the section with system and security.

Now all that remains is to enter the power tab. It must indicate the level of performance that is needed. Select the maximum value. In the additional parameters tab, specify the desired value. Often this section is hidden. So there is no need to be afraid of this.

Immediately after these manipulations, we try to connect the gadget to a power supply network. Only after this can you try to check the sound quality again. If everything is in order, then the problem was precisely the lack of power.

There is also another type of noise that may not occur often. It manifests itself in the fact that when scrolling the mouse, this sound can be clearly heard in headphones or speakers, if they are connected. This may not irritate some people very much, but a certain group of users are very stressed by it.

Therefore, it is necessary to consider this error option. The reasons can also be very different. Therefore, it is extremely difficult to establish the real “culprit”. So it’s worth trying a few manipulations that will really help.

You can also resort to connecting a mouse to a different port or use a completely different mouse. You can also purchase a wireless version instead of a wired one. This may help in some situations. So problems with the mouse can also cause unusual noises.

Whatever the cause, it can be identified and then all necessary efforts can be made to eliminate its consequences. This instruction will certainly help.
