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, or make noise - the sound can deteriorate in different ways, but the essence is always the same. This can either spoil the impressions of the sound of the headphones or make listening to music with them completely impossible. What should you do if the sound in your headphones is distorted in one way or another?

Why can headphones produce noise?

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

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

In addition to interference from other electronics, hum can be caused by poor wire shielding. In this case, the background appears when the headphone wire or the connector to which they are connected comes into contact with metal. Most often, this situation manifests itself when connecting headphones to the line output on the front panel. personal computer. This output connects to motherboard using very flimsy wires that are exposed to a metal casing system unit, which leads to background noise in the headphones. To get rid of the hum, just move these wires. But this will not completely solve the problem - to prevent the background from appearing again, you need to either cover the case with aluminum foil from the inside, or simply connect the headphones to another connector - for example, on the speakers or on the back wall of the computer.

Another one possible problem, causing background noise in the headphones - a breakdown of the sound card or a malfunction of its drivers. If the board is broken, you will have to replace it or repair it in service center. You can replace the drivers yourself. To do this, you should find out the sound card model in the device manager, which is available in the properties menu of the computer running the operating system. Windows systems. After this, you need to go to the sound card manufacturer’s website and download the necessary software.

Background in headphones when connected to a phone

If the headphones are connected not to the computer, but to a mobile phone, the background noise may be caused by a mismatch between the headphone plug and the connector on the smartphone. 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 contacts, two of which are used for audio output, the third for audio input from the microphone, and the fourth is ground. In headphones produced after 2011, the order of connecting the contacts has changed - the ground and microphone have swapped places. The connector in phones has changed accordingly. Therefore, when connecting old headphones to modern phone or vice versa, the connection may not occur correctly, which leads to the appearance of hum in the speakers - the device is not grounded as it should.

Causes of other sound distortions

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

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

But this is very special case. In general, headphones squeak and wheeze, usually due to mechanical stress 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 cable fraying, losing insulation, which is why sound distortion appears.

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

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

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

Cable repair

Unlike broken copper wires, which can be detected with a multimeter, loose 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 stops being distorted. Once you find a place where the sound is clear again, the damage can be repaired. In this case, there is no need to cut the wire.

In the designated place, use a sharp utility knife to clean off the cable braid. Under it you will find three wires - two of them conduct the signal to the speakers, while the third grounds the device. They all must be separated from each other. To restore damaged insulation, simply wrap each wire with electrical tape and then cover the repair area with heat-shrink tape.

Plug repair

Sound distortion can be caused by two problems with the plug:

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

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

Speaker repair

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

If there are screws on the headphone body that fasten individual parts, and you can disassemble it, do it. The copper wires of the cable must 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 your headphones, make sure that the problem is with them and not with other equipment.

Almost all home computers and laptops are used for work, participating in a variety of gaming processes, traveling around social networks and other sites and, of course, you cannot do without 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 the most different options. 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.

That's why they appear in the end various noises. Problems of this nature may accompany the reinstallation process. operating system. That is, when the user executed loading Windows or updated the system, then 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 the devices are indicated opposite exclamation marks yellow or red. 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 reason 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 according to the most various 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.

Can still be identified bad contact between the nest network card device 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 the data simple steps are able to 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 optimal size and the problem will be fixed.

Adjusting sound settings

Difficulties often arise precisely for this reason. It's hard to even imagine what correct setting 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 setting provokes 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.

Equipment Bad quality

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

And the whole point 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 sound be achieved good quality. 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.

In order to exclude 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. Choose maximum value. In the tab with additional parameters should be specified 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 be too annoying for some people, but separate group users get very stressed out about this.

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 definitely help.

Getting rid of noise in headphones when connected to the front panel of a PC using the example of the AirTone MC-6010 case

Probably everyone has encountered this problem - people close to you are sleeping around, but you want to listen to something while sitting at the computer. Or just watch a video with sound. It seems that you don’t need a high-quality audio system for this, plug the headphones into the front jack of the computer and have fun. It wasn't like that. Greetings, dear friends. My story began with the fact that I changed my personal computer case. The victim of my adventures was the AirTone MC-6010. I've been eyeing it for a long time, big, beautiful, well made... I spat and bought it. How much can you poison your soul? And satisfied with the barrel of honey, the bear wandered home... But the bear did not rejoice for long. There was also a fly in the ointment here. Someone stepped on our bear's ear. I connect headphones to the front (front) panel connector, and I hear a beeping sound from them. I move the mouse and the squeaks change. I scroll through the page with the wheel and it changes too. And this sound is so annoying that it was decided to change something.

The first thing I did was look for information on the Internet. I refused advice to update the BIOS, and realized that manual therapy was not enough. Apparently something was done with the layout of the ground. We'll open it. Having decided on this idea, I abandoned it for a long, long time. I just didn’t want to go through all the trouble of stirring things up. But by chance I recently decided to check motherboard to my friend, and shook up everything that was in my system unit. Well, I decided to figure out what was going on for the company.
So, we are faced with the first task. Disassemble the case and get to the insides of the front connector panel. Ok, let's get started. Having disassembled half of the body, removing the door opening mechanism and much more, I once again made sure that I had not noticed any fasteners somewhere. And so it turned out. So, our panel with connectors is attached: a self-tapping screw in the front part, access to which is through a rectangular slot in the metal from below. Two screws in the middle. And attention (!!!) there is another self-tapping screw behind the far latch under the wiring harness. It is this wiring harness that prevents it from being seen. After this, move the 3 latches with your hands and pull top panel up and towards yourself. It will resist a little, since there are 2 more non-locking latches installed in the front part. Under our pressure, they also carefully emerge from their seats without any harm.

Hurray, the hardest part is over! I hope... We see a neatly made case in which everything is attached. We take a screwdriver and unscrew the two bolts on the sides that hold it...

The first thought is wow, there’s so much here... But my hands are already trying to move on) I must say that I liked the implementation. Everything is done neatly, everything is detachable for ease of use. Well, let's continue. So, we are looking for land. To do this, we need a pinout diagram for the HD audio connector and a tester. The first one is easily found on the Internet, the second one can be found at home. Well, or if you’re really unlucky, then in any radio store. Here is the first one from the list:

Having found the wire we need, we call it with a tester. I didn't even have to do this color coding The wiring was done very neatly, and I had no problem finding the mating contact on the connection block to the panel. In the picture below it is highlighted in red.

Well, of course, the cause of all the problems is immediately visible. The pins of the ground buses of the audio path and USB/E-Sata ports were soldered together. We turn it over and make sure that the earth diverges into different wire harnesses. Of course, ours USB ports give strong interference, which are strengthened by the resulting earthen loop. So it needs to be cut. Scalpel please! Why not? Well... then a paper knife! (if you don’t have it, you can use the regular one, but it will be a little less convenient). We're cutting! Stop. What exactly are we going to cut? Well, I'm in a hurry again. We plug an empty plug into the audio connector and find where the ground is connected to it. In the picture above I marked it in blue.

What would be the best way to do it? Cut it off and connect directly to the wire? Then the panel will become one-piece. What if... After measuring the dimensions, I came to the conclusion that there is more than enough space in this case. Then we carefully isolate these pins from the common ground polygon, and connect them to each other with jumpers from a piece of wire. Now let's cut!

Every contact pad The pin is connected to the common polygon by four thin bridges in the corners. Carefully cut them, to be sure, ringing them with a tester for lack of contact. Ready! Now we need to connect them to the main ground pin. How? You can use any wire that suits your aesthetic needs. Preferably, of course, without extremes. For some reason, I immediately imagine a thin ligature of an engraved pattern on the surface of the insulation... Ah! Let's continue! Well, I didn’t find the wire right away. From computer power supplies it is a bit thick, from twisted pair cables it is thin and brittle. No, hunting for something more civil. After rummaging through the bins, I found this work, probably from Soviet times. The next generation will no longer understand where he came from. I barely caught it myself

This is an audio cable that connected in old computers optical drive with motherboard. Just right! Cut off the black wires. Let's see. Stranded, tinned copper. It couldn't come at a better time. Great! We take a soldering iron, a desoldering pump, and get to work. We separate the required pin from the other three with which it is filled with solder. We complete the job with a knife, cutting the contact strips going to the common ground. In this place, be careful, there is a path next to the pin on the left, which has nothing to do with our showdown. You must be careful not to damage it. We use a tester to check the work done and carefully solder two jumpers from the chosen wire.

Rejoicing at the completion of the work, I assemble the entire case and turn on the computer. Hooray! No more noise in the headphones! True, there is no sound either... I collected it, of course. But he did everything carefully, it seemed like there was nowhere to make a mistake! After digging through the driver settings, I found out that not everything is so bad. The panel works, but it does not detect that a device is connected to it. If you disable the detection function, the sound goes through the headphones. Internet again? Are looking for! It turns out that the panel I got was not HD Audio, but simply AC 97. After reading the information, I learned that this is exactly what distinguishes them. The ability to determine that a device has been connected. Not good. Having searched a bunch of forums, I still haven’t found information on what algorithm is used to determine it. But the pinout diagram, that is, of both standards. So, let's go looking. We disassemble the case again, this time removing only the top panel. By the way, I managed to put the self-tapping screw that I was screwing through a rectangular slot in the metal in the wrong place, leaving marks on the board. Be careful, don't repeat my mistakes.
Having reached the board again and armed with a tester, I begin to make calls... Well, of course! How did I not notice right away! One of the four pins combined together also goes into the same wiring harness and belongs to HD Audio. As they say in the pinout, this is a certain “–ACZ_DET”. So it becomes clear what kind of contact this is. He is responsible for determining the type of connected panel. Again, take the soldering iron, desoldering pump and knife. We also separate it from the other pins, isolate it from the ground polygon and combine it with the HD Audio ground pin.

Question from a user

Hello.

I have a problem with my PC: from the speakers and headphones coming some extraneous noise (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 too much quiet sound - 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 home. 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, cables longer than 2-5 meters (in the most ordinary situations, for household use) - I do not recommend using it.

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 observed extraneous noise.

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 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 panel Windows management by the address: Control Panel\Hardware and Sound .

It will display several of your sound devices. Open the properties of the one through which there is a sound by default (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 input 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 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 you set important parameters for your equipment. As a result, certain sound distortions may occur.

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

You may also find programs for automatic update drivers in the system. 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 socket. Even better if it is connected to an outlet network filter(not Chinese, but standard quality, or UPS), 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.

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 mobile phone not on a computer desk, or on 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, more quality speakers(and, as a rule, more expensive), 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 users laptops...

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 energy consumption does not allow issuing 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 in the past, now there are modern ones 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...

Good day.

Most home computers (and laptops) come with speakers or headphones (sometimes both) connected. Quite often, in addition to the main sound, the speakers begin to play all sorts of extraneous sounds: the noise of mouse scrolling (very common problem), various crackling sounds, trembling, and sometimes a slight whistle.

In general, this question is quite multifaceted - there can be dozens of reasons for the appearance of extraneous noise... In this article I want to point out only the most common reasons why extraneous sounds appear in headphones (and speakers).

Reason #1 - problem with the connection cable

One of the most common reasons for the appearance of extraneous noise and sounds is poor contact between the computer's sound card and the sound source (speakers, headphones, etc.). Most often, this happens due to:

• damaged (broken) cable that connects the speakers to the computer (see Fig. 1). By the way, in this case you can also often observe the following problem: there is sound in one speaker (or headphone), but not in the other. It is also worth noting that a broken cable is not always visible to the eye; sometimes you need to install headphones to another device and test it to get to the bottom of the truth;
• poor contact between the PC network card socket and the headphone plug. By the way, very often it helps to simply remove and insert the plug from the socket or turn it clockwise (counterclockwise) to a certain angle;
• loose cable. When it starts to hang out from a draft, pets, etc., extraneous sounds begin to appear. In this case, the wire can be attached to the table (for example) with regular tape.

By the way, I also observed the following picture: if the cable for connecting the speakers is too long, extraneous noise may appear (usually subtle, but still annoying). When the length of the wire was reduced, the noise disappeared. If your speakers are very close to your PC, it might be worth trying to change the length of the cord (especially if you use some extension cords...).

In any case, before you start looking for problems, make sure that everything is in order with the hardware (speakers, cable, plug, etc.). To check them, just use another PC (laptop, TV, etc.).

Reason #2 - driver problem

Anything can happen due to driver problems! Most often, if the drivers are not installed, you will have no sound at all. But sometimes, when the wrong drivers were installed, it may not be observed at all correct work device (sound card) and therefore various noises appear.

Problems of this nature also often appear after reinstallation or Windows updates. By the way, Windows itself very often reports that there are problems with drivers...

To check if everything is ok with the drivers, you need to open device Manager (Control Panel\Hardware and Sound\Device Manager- see fig. 2).

In Device Manager you need to open the " Audio inputs and outputs"(see Fig. 3). If yellow and red exclamation marks are not displayed in this tab next to the devices, it means that there are no conflicts or serious problems with the drivers.

Reason #3 - sound settings

Quite often, one or two ticks in the sound settings can completely change the clarity and quality of the sound. Quite often, noise in the sound can be observed due to the inclusion of PC Beer and the line input (and other things, depending on the configuration of your PC).

To configure the sound, go to Control Panel\Hardware and Sound and open the tab " Volume settings"(as in Fig. 4).

In the “Levels” tab there should be the treasured “PC Beer”, “CD”, “Line input”, etc. (see Fig. 6). Reduce the signal level (volume) of these devices to a minimum, then save the settings and check the sound quality. Sometimes after these settings are entered, the sound changes dramatically!

Reason #4: Speaker volume and quality

Often, hissing and crackling in speakers and headphones appears when their volume reaches maximum (on some, noise appears when the volume rises above 50%).

This happens especially often with inexpensive models speakers, many people call this effect “jitter”. Please note: this may be the reason - The volume on the speakers is turned up almost to maximum, and in Windows itself is turned down to minimum. In this case, simply adjust the volume.

In general, it is almost impossible to get rid of the “jitter” effect at high volumes (of course, without replacing the speakers with more powerful ones)…

Reason #5: Power supply

Sometimes the reason why noise appears in headphones is power supply diagram(this recommendation is for laptop users)!

The fact is that if the power supply circuit is set to power saving (or balance) mode, perhaps the sound card simply does not have enough power - this is why extraneous noise is observed.

The solution is simple: go to Control Panel\System and Security\Power Options- and select the mode “ High performance"(this mode is usually hidden in the additional tab, see Fig. 7). After this, you also need to connect the laptop to the power supply, and then check the sound.

Reason #6: Grounding

The point here is that the computer case (and often the speakers too) passes electrical signals through itself. For this reason, various extraneous sounds may appear in the speakers.

To eliminate this problem, one simple trick often helps: connect the computer case and the battery with a regular cable (cord). Fortunately, there is a heating radiator in almost every room where a computer is located. If the reason was grounding, this method in most cases eliminates interference.

Mouse noise when scrolling the page

Among the types of noise, the predominant one is extraneous sound- like the sound of a mouse when it scrolls. Sometimes it is so annoying that many users have to work without sound at all (until the problem is fixed)…

Such noise can occur for various reasons; it is not always easy to establish. But there are a number of solutions to try:

1. replacing the mouse with a new one;
2. replacement USB mice to a PS/2 mouse (by the way, many PS/2 mice have a mouse connected via an adapter to USB - just remove the adapter and connect directly to the PS/2 connector. Often the problem disappears in this case);
3. replacement wired mouse to wireless (and vice versa);
4. try connecting the mouse to a different USB port;
5. installing an external sound card.

PS

In addition to all of the above, speakers may begin to produce noise in the following cases:

• before a mobile phone rings (especially if it is close to them);
• if the speakers are too close to the printer, monitor, or other equipment.

That's all I have on this issue. I would be grateful for constructive additions. Good job 🙂
