Extraneous sound and noise in headphones and speakers: where does it come from and how to eliminate it. Hissing, noise, crackling and other extraneous sound in speakers and headphones - how to find and eliminate the cause? Headphones are making noise on the computer, what should I do?

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 both spoil the impressions of the sound of the headphones and 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 hum in speakers, be it headphones or the emitters of any other acoustic device, is usually caused by physical impact on 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 comes in 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.

One more 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 operating system Windows. 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 for 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 a 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 a 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 hold individual parts together, and you can disassemble it, do so. 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.

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

Noise can appear due to the operation of the computer, the operating system is loaded, information is processed, all this is accompanied by unpleasant crackling and squeaking. Fortunately, the problem can be solved, but first you need to find out what is causing the extra sounds.

Throwing away your old device and buying a new one is an extreme method of solving the problem. In fact, noise in headphones or speakers can occur due to damage or incorrect connection of wires, drivers, and even Windows settings.

PROBLEMS WITH CONNECTION CORDS

Often a hissing sound appears when bad connection PC sound card and sound playback device. There are three options:

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

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

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

TROUBLES DUE TO DRIVERS

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

Such malfunctions appear after updating the drivers or installing a new package. This problem is reported by Windows OS.

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

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

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

In any case, if updates are available, you should do so. Perhaps the extraneous noise will disappear.

SETTINGS AND CONFIGURATIONS

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

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

Fig.2. At the second stage of work, click LMB on the “Speakers and headphones” icon

Fig.3. The Levels menu has settings for PcBeep, CD, etc.

• We set all these functions to the value 0, save the configurations and check whether this solves the problem.

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

OTHER REASONS

DEVICE QUALITY

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

This problem plagues all owners. inexpensive devices, this is also called the “jitter” effect. Also, noise appears when the volume level of the speakers is set to maximum, and in the operating system, on the contrary, at minimum configurations.

In such a situation, we find a “golden mean”

Solving the problem with “jitter” when the volume is increased is almost impossible. The only solution is to buy new speakers.

WEAK SOUND CARD

In most computers, this part is installed directly into the motherboard and is purchased all together. Purchasing a separate card costs money and is not a popular solution.

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

Low-cost PCI options are slightly better at this issue, but they also have the same problem.

IMPROPER PLACEMENT OF PARTS

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

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

NO GROUNDING

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

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

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 (reminiscent of crackling). 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 ( exact model Don't know). 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 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 ordinary 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 touches it accidentally.

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 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 rear 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 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, 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 Windows versions(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 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, this is done 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. Even better if it is connected to an outlet surge protector(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.

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 mobile phone 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, "unusual" desk lamp may 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 output 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 that 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...

When establishing a connection peripheral devices When using a PC, you should be careful and attentive, because the complexity of the headset complicates the connection process. Audio recording devices and headphones are often connected to the same speakers. These components are extremely convenient for communicating on the Internet. It is difficult to imagine a modern user without these devices. In fact, connecting is not so difficult if no problems arise during it. The same users very often ask the question on forums: noise in headphones on a computer - how to remove it? To make your life easier, we recommend that you familiarize yourself with detailed information on this topic.

Where does the noise come from?

First you need to understand where this noise comes from, because many “users” are familiar with this problem. Often this problem occurs only temporarily, but for some people it takes a very long time to get rid of it. Let us reveal the secret that the nature of this problem can have different beginnings. Noises can appear for a variety of reasons, so it is very difficult to predict which measures will return the situation. Problems may be caused by settings or technical problems.

How to remove noise from headphones? To eliminate this problem, you need to identify the roots of the problem.

Sound card

Perhaps we should start with the components inside a desktop personal computer or laptop. Map sound processing it may simply be damaged or the new equipment does not want to work with it. In headphones, “disturbances” can manifest themselves in the form of noise and crackling.

All this can be corrected only by completely replacing or repairing the card at a service center. Perhaps after these measures the noise will disappear.

Earth

This reason can hardly be called common, but it should not be excluded from the list. We are talking here specifically about the ones we power our headset with. In this case, extraneous sounds may also occur.

Important! If you are working with a laptop, then it is not a fact that the components are motherboard have grounding. If it is missing, you need to think about replacing parts or simply accept the unpleasant consequences.

Why do the speakers on my computer make noise and how can I remove this background? It may not just be the devices that everyone thinks about.

Third party equipment

Audio output devices may hiss even due to connected devices. In this case, problems do not appear immediately. In other words, you may suddenly experience a monotonous noise when you connect your mouse.

Important! This problem can also occur when connecting a keyboard.

The noise is due to the following reasons:

• During pairing, data is actively transferred to the PC. It is recommended that you avoid using USB ports that you are having problems with. It is best to use other interfaces for connection or think about repairing the outputs.
• The USB port is damaged. Repair is also perfect here, but in practice, users simply start using other ports. The problem is not of great relevance, since it does not occur very often.

Wire

How to remove noise from headphones in other ways? Perhaps the problem lies in the model of the headset you are using. Absolutely all headphones are divided into:

1. Wired devices. The connection is based on a cable.
2. . The connection is based on a wireless communication module.

Software

This factor is key for everyone computer devices without exception. In practice, of course, such cases do not occur so often, but it is better to check everything from all sides. Extraneous sounds during operation may occur due to irrelevance sound drivers or their absence at all. To get out of this situation, you will need to reinstall the software to ensure normal operation of the headset.

Maximum volume level

The background can also interfere with the wrong sound settings. It doesn't matter at all whether you use a microphone or not.

Important! Use the tips from our post to...

If all parameters are set to maximum values, that is, there is a risk of hearing creaks and wheezing. The situation can only be corrected by lowering the volume level. There is nothing complicated about this action.

Video material

Now you have learned how to remove the background from the speakers on your computer using different methods. Use only high-quality devices and do not forget to periodically update the software.
