The speakers on the computer are noisy, what should I do? Hissing, noise, crackling and other extraneous sound in speakers and headphones - how to find and eliminate the cause

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 shell out for expensive options no one wants it, 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 may appear due to damage or incorrect connection 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 the network card is of 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, then 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, when available updates should do this. 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 actually 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 of inexpensive devices; it 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.

Inexpensive PCI options are a little better in this regard, but they also have this 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 regular socket, 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 (resembles a crackling noise). 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 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 speakers are located 2 meters from 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 common situations, for household) - 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 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 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's 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 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 outlet. 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.

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 screen 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 computer desk, or by at least, spread across different angles telephone and speakers. 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 more clear sound even at high volume, and the noise is only 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 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 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, to this one sound card You can’t connect any specific equipment, but you can connect ordinary classic headphones and speakers, a microphone, 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 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...

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

The sound must be clear and loud, and its distortion is a big problem that anyone can encounter Windows user 10. If the sound on the computer begins to crackle, wheeze, sound muffled, hiss, or there are other problems with it, you need to fix the problem as soon as possible. In this article, we will look at the main reasons why similar problems with sound in Windows 10, as well as ways to fix them.

Important: Before you start trying to fix software malfunction, make sure that the problem is not hardware. If the sound hisses from speakers connected to a computer or laptop, try checking them by connecting sound system to the player or phone. In a situation where the built-in laptop speakers wheeze, on the contrary, connect to laptop computer external speaker system and see how it sounds. You can also try disconnecting the laptop or computer connector from the sound card and connecting it again.

The sound on the computer wheezes due to effects

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

Sound effects on your computer may turn on due to changes in system settings various applications with administrator rights. Check whether wheezing, hissing or muffled sound is associated with Windows effects, you can in the audio settings. This is done as follows:


Saving changes made, make sure that the sound on the computer has returned to normal and become “clean”. If it continues to crack, wheeze, hiss, or have other defects, proceed to next point instructions.

Sound hisses and crackles in exclusive mode

Some versions of Windows 10 may conflict with sound card drivers, causing the user to experience defects when listening to audio in exclusive mode. Also, problems with exclusive sound mode may occur on weak computer. To exclude the possibility of crackling, hissing and wheezing when playing sound due to the exclusive mode, we recommend trying to disable it.

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

Check if the sound improves after turning off exclusive mode.

Sound problems due to incorrect drivers

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

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

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

Quiet sound in Windows 10 due to communication settings

Another innovation modern versions Windows automatically mutes the sound output various programs, when making a call, for example, in Skype. There may be situations when this option does not work correctly and, due to some errors, constantly keeps the sound muted, believing that the computer is in call mode.

To exclude the possibility of problems with quiet sound because of this Windows features, you can try turning it off and check if the problem persists. Disable the option in the sound settings:


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

Sound problems in Windows 10 due to incorrect playback format

Modern sound card models support almost any audio playback format that can be offered by the operating system. Windows system. However, if your computer has old map, this may cause problems.

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

It is worth noting that the 16-bit format at 44100 Hz is supported by almost all sound cards, and it is still used over time earlier versions Windows.

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

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 - the reasons for the appearance extraneous noise there may be dozens... 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 noises and sounds is bad 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 socket network card PC and 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 this tab does not display yellow and red icons next to devices exclamation marks- means that there are no conflicts or serious problems with 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 speaker models; 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) allows electrical signals. For this reason, various extraneous sounds may appear in the speakers.

In order to exclude 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.

Rice. 8. PS/2 and USB

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 🙂

Instructions

First you need to determine the cause of extraneous noise in the speakers. Most often, this may be due to poor shielding of the amplifier and/or cable. To check this, hold the cable in your hand. If the noise becomes louder after this, simply wrap the cable with foil or replace it with a new shielded one. As for the latter, this is the most best option, since there are no magnetic fields will not interfere with the sound from the speakers, and the sound itself will be cleaner.

Noise in speakers may occur due to a lack of grounding. Cheap enclosures often allow electrical signals to pass through, causing interference throughout the entire system. To solve this problem, it is recommended to ground the computer. The most simple option is connecting the housing, for example, to a battery. This way, the tension will be removed from the case and the noise will disappear.

Try setting up your speaker mixing system. To do this, go to the Start menu - Control Panel - Sound. In the “Playback” tab, find your speakers, right-click and select “Properties” from the menu that appears. Then in the window that opens, find the “Levels” tab and disable the “Line In” function in it.

If all of the above methods do not help fix the problem, there is only one thing left to do - purchase new speakers.

Sources:

  • Why do the speakers sound when you turn off the computer?

Most speakers that are specifically designed for central channel, are shielded in advance from magnetic influences, but if you use floor-standing acoustics with a full range or unshielded for the center speakers, you will inevitably encounter the unpleasant phenomenon of “color spots” on the TV screen. This effect is possible when too short distance between the front speakers and the TV.
