How to remove noise in wireless headphones. Strying sound and noise in headphones and columns: where he is taken from and how to eliminate it. Maximum sound - problems are provided

Causes of noise in headphones:

You have connected the headphones to a computer or laptop, and instead of a pleasant and favorite music, hear an annoying hiss or crackle, who will like this? At the same time, you do not understand why there are noise in the headphones, where he appeared and what to do with it.

The most unpleasant in the effect of noise in the headphones is that it is very difficult to find out because of what it appeared and how to eliminate it. There can be a lot of causes of cod in headphones, the usual cause search algorithm bad work The headset is a consistent integrity of potential sources of noise, their exception or isolating and further verification. In theory, it looks simple, but in practice such an algorithm is completely impossible.

For example, you have only one computer that is connected to the outlet, which is inserted into the concrete wall, the apartment has repairs and to install the computer to another place, or another room, is impossible, because There is no place for him. And so we can eliminate all possible causes of extraneous noise in headphones.

However, we can start with the easiest and most obvious potential causes of interference in the headphones, and there is a check of their result, we will not have the result, we will only hope that in the future this problem is self-sustaining. For example, the neighbors turn off the perforator, or after a while you buy a voltage stabilizer through which the computer is connected.

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

Cable damage - very frequent cause of hissing and cod in headphones

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

Carefully consider the headphone cable, it must be absolutely whole, it should be the same density inside inside. Spend the entire cable with your hands, perhaps in some place inside the cable was interrupted or once you beat the cable too much and the copper veins inside it broke off.

If, after a visual and tactile check, the cable does not cause suspicion, check the Jack, its articulation and the audio accession itself, in which you connect headphones.

Check out how well you insert Jack into the nest, it must come easily, with a slight click and keep it firmly. Jack should be in the nest to the end, should not be visible part of Jack.

Sometimes, due to the characteristics of the structure of the nest of about 1 mm, Jack remains visible, but no more and the phenomenon is rare.

Bad contact is one of the most common causes of noise and cod in headphones. Wipe the Jack with a dry soft cloth, it may be contaminated or covered with a layer of oxide.

If the wire suspicion does not cause and jack to the nest plugged, and the noise remains, you need to continue the search.

Technical condition of headphones - the possible cause of white noise

After checking the wire and Jack did not give the result, it is necessary to check the headphones themselves.

Carefully inspect them, perhaps recently they fell on a solid surface, cracks or other traces of damage appeared on the housing.

Be sure to try to connect headphones to another sound source, such as telephone, TV or tablet.

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

If when connected to another device white noise Disappeared, it means that the headphones themselves are in order together with the wire and jack, and we move to a further search for the occurrence of a cod.

Cheap columns can cause noise in headphones

If noise in headphones occurs when connected to a computer or laptop, to which inexpensive multimedia columns are connected at the same time, try to turn off the speakers and check whether the interference in the headphones disappeared.

The fact is that inexpensive columns are harvested from cheap items, but most importantly - when they are assembling, they are strongly saved on soldering, wires and the overall level of construction. Therefore, inside the columns may occur bad contact or closure, which will distort the interference electric chainAs a result, outside the headphones may appear.

The speakers need to be turned off completely, and not only turn off their power.

If the full disconnection of the speakers from the computer did not help eliminate the noise in the headphones, go to next step troubleshooting.

No grounding - the most common cause of interference in headphones when connected to a computer

For some unknown, the reasons for me in many homes do not have grounding. In general, it is not so scary, traditional household appliances, such as irons, heaters, filters and air conditioners work normally. But it costs to connect equipment unnecessary power grid, which is very sensitive to the quality of the power supply, as problems immediately come out.

The computer connected to an uncontrolled outlet is direct expensive not only to noise in headphones, but also possible reason The computer output is entirely due to the impact on it of static electricity.

A normal way to solve this problem is to ground the socket to which the computer connects. But it is not easy to do it, if at all possible. For this you need to call the electrician, however, in this case, most likely, it is most likely to shift the wiring across the apartment, and this is already a serious repair.

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

You need to take the usual copper wire of a small cross section, from two sides with bare contacts. One end to lean to the computer housing (preferably to the back of it), and the other to the battery. To lean the wire to the painted part of the battery is useless, you need to lean to the metal of the battery, so you have to search for such a place. Usually naked metal can be found on the rear of the battery.

If you did everything right, and the noise left or significantly decreased, it means that the matter is grounded.

Remember: it is impossible to ground through the battery count permanent solution. Such a grounding can lead to a complete failure of the entire computer, only your neighbor grounds serious equipment to the battery, like a computer, having received a powerful discharge of electricity to the body, will fail. This is only a method of checking, no more.

But what to do if you know exactly that the sockets have a grounding, and the check with the wire did not give anything? We continue searching the cod in the headphones.

The noise from the microphone is one of the many reasons for the occurrence of interference in headphones.

We looked at possible sources of noise problems in headphones that concern material intervention, now we have problems that relate to the configuration of computer equipment.

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

Even if your sound card The microphone is not connected, noise from the microphone socket can occur.

In order to check this hypothesis, you need to go to the sound of the sound of your audio card, find the slider that adjusts the volume level of the microphone and reduce it to zero. Either, if there is such an opportunity, turn off the sound from the microphone.

If the cause of noise in the headphones was a microphone input, then the disconnection of the sound from it should be fully corrected.

In order to get to the microphone volume settings, open the control panel, find item "Equipment and sound" And go to it.

Now find item "Sound" And go to it.

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

In a new window, find the tab "Levels", and either slide the microphone volume slider as to the left as possible until its value takes the zero indicator, or press the blue speaker icon, which is located to the right of the volume level. Near the speaker should appear a red crushed sign. This icon will mean that the microphone is completely disabled in the system. It is preferable to disable it, and not just reduce the volume level.

One of the varieties of problems with the microphone entrance or the microphone itself is its high sensitivity. This problem can be solved by incorporating the microphone noise cancellation mode.

Almost all modern sound cards have such a mode. If you find out that the cause of the cod is a microphone, but it is needed, then try to turn on noise cancellation mode if it is. This should solve the problem.

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

Not only the interference of the microphone can cause hissing in the headphones, the same interference can also give the adjacent audio card inputs.

Depending on the sound card model, it may be additional inputs To connect additional equipment. They can wear the following names:

What u hear
Line In.
S / PDIF.

Any of them can become a source of interference at a certain coincidence. Similarly, as you have reduced the volume of the microphone, you need to reduce or completely disconnect the sound from all these sockets.

To do this go to the panel windows management.

Then find a point there. "Equipment and sound".

Then click on the section "Sound".

In a new window, enter the Playback tab, select Active Speakers (a device that reproduces sound in headphones in this moment) And click on the "Property" button.

Next, I can't make a screenshot, because In my case, the volume level of all inputs and outputs is adjustable via a special software that controls my sound blaster sound card, in your case, most likely the tab will be available. "Levels"When you enter which you can disable all inputs and outputs of your sound card.

To check, leave only the output to the headphones, and all other possible outputs and inputs, disconnect or reduce their volume to zero.

If the problem of hissing headphones was in one of these items, it will have to disappear.

The volume level is paradoxically, but the fact, it can be the cause of interference in the headphones

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

Sometimes it happens that the headphones have their own volume control, plus there is an additional volume control in Windows, and there is still a volume control knob in the application, the sound of which you listen to (play, player).

In order for any equipment that has its own hardware volume control, it is good, it is necessary to make all the volume control regulators (especially the main volume slider in Windows) were 100% installed. And the final adjustment of the volume is using the hardware volume control.

To resolve Hissing, follow these steps:

Fully disconnect the sound in the headphs using a hardware regulator (buttons or twisters on the headphones themselves)
Volume in Windows 100%
Set the volume in the application 100%
Start gradually add volume on headphones and bring it to a comfortable level.

The fact is that the volume control regulators artificially reduce the volume of the sound, and then in the headphones you have to unscrew the volume to the maximum to listen at a comfortable level. However, for any technique, be it headphones, columns or car engine, long-term work on the limit possible is extremely destructively reflected on the characteristics and properties of the unit.

When setting the maximum volume with hardware on headphones, you strengthen the entire noise that comes from the computer, plus add distortion that appear in the headphones themselves at the maximum sound level.

Therefore, you need to adjust the volume by the method that I indicated to minimize possible distortions and noise from the headphones themselves, as well as remove the artificial increase in unwanted noise.

Imagine the situation, you bought new excellent headphones, but when you have connected them for the first time and started listening to the sound was just awful. But as possible, because in all the reviews that you read before buying, journalists and bloggers wrote that the headphones are great.

Let's look through the most common reasons that make even the most best headphones sound awful.

Headphones sound too quiet

You bought headphones, connected them to your compact player Or a smartphone, and they sound quiet and sound is inexpressive, flat. It's all about the disadvantage of nutrition. Many headphones impose an increased demand for sound source, which is why there are special labeling on headphones that they are compatible with smartphones. If there is similar labeling on the headphones, then the manufacturer created them specifically to work in a pair with a smartphone. And if there is no marking - no one will give you a guarantee that a specific model of headphones will be perfectly compatible with compact sources Sound.

The main parameter to which you should draw your attention when choosing headphones for mobile use - Resistance. For smartphones and players, it is not recommended to choose headphones with resistance above 32 ohms. Yes, some phones are able to dig headphones and with greater resistance, sometimes up to 60 ohms, but there is no guarantee that you are lucky. Therefore, when buying, you pay special attention to this parameter.

In general, it is believed that the higher the resistance of the headphones, the cleaner they can reproduce the sound. But remember that this feature is important for domestic listening, where there are no extraneous sounds, there is a special amplifier for headphones. In this case, you can really catch the difference in sound. But we are talking about headphones for your phone and listen to them, most likely, on the street, in transport or in the sports hall. Therefore, you have no reason to chase headphones with high resistance, it simply does not have a practical meaning.

Solution: Portable Headphone Amplifier

If you firmly decided that you need an uncompromising sound in any situations and bought high resistance headphones, you need a portable headphone amplifier. Such an amplifier does not occupy a lot of space, it can be easily wearing with me. Although, of course, you need to envisage where you put it.

Just be sure to look at the specifications on any amplifier you buy, and make sure that the number of "output resistance" in the specification is less than 1/8 of the headphone resistance that you want to use. In this case, you will achieve perfect sound.

Houses headphones sound excellent, but in the subway and transport it is impossible to listen

Must disappear, but the headphones are not here. If you listened to their homes, you liked the sound, and in the subway you noticed that this is not a sound - and not digestible noise porridge, the headphones are not here. Human hearing is to blame.

Like any microphone, our ears are not perfect. The fact is that our ears capture that sound that sounds louder than the other, especially this effect is noticeable if the frequencies of these sounds are close or coincided. In this case, you will hear that sound that sounds louder. Nothing can not be done with that.

Solution 1: Avoid places with high levels of background noise

This is an obvious and simple solution, it is a pity that in most cases it will not suit us. After all, you need a subway to get to work or study, and for the sake of songs in headphones it is silly to use another type of transport.

Solution 2: Block the outer noise

This is one of best decisionsI can recommend you. There are several ways to drown out external noise to better perceive music in headphones:

Use intracanal headphones with foam empty. Such headphones can significantly reduce the level of external noise. Fully, of course, it will not be possible to exclude it, but you will at least start listening to music, and not noise wheels in the subway;
If you use headphones open type - Stop doing it. Open-type headphones are not isolation from the outside world, try moving on a closed type headphones with a high level of passive noise insulation. About what headphones you will suit the most you can find out by reading the review or reviews on specific model, other solutions, unfortunately, no;
Use earnings with active noise reduction. I think this is the most efficient and simple way out. Modern headphones with a system of active noise reduction are very well protecting you from external noise, the leader among such headphones is the model of the BOSE. There are similar systems and other manufacturers, but on my experience, the BOSE model most effectively coped with this task. In addition, most often such headphones are wireless, which means you will not only be nice to listen to music, but also convenient, because There will be no interfering wires.

Solution 3: Increase the volume in the headphones

Do not do that! Technically, if you make the volume of music in headphones above, you will hear it better. But you also significantly increase the likelihood of damage to your hearing, and it will be impossible to restore it. In the subway, you will not be able to adequately appreciate the volume of music, which will be high enough to shut up the sound of the car, but not sufficiently loud, so as not to harm your hearing. Therefore, I recommend you configure and remember the maximum level of volume in the headphones in a quiet environment. For example, put the headphones at home, and start increasing the volume on the phone. On the screen you will see the volume slider. Remember its position when the sound will seem loud and not comfortable, and never exceed it. In the subway you may seem that the music is playing quiet, but looking at the volume slider on the screen you will easily understand that it is not necessary to raise the volume above. It is better to drive a couple of stations without music in general than to suffer from a hearing impairment.

Bluetooth Headphones sound bad in a pair with my phone

Many modern phone manufacturers begin to refuse traditional Jack for headphones. They do it by different reasonsBut we, as consumers, remain only one thing - use Bluetooth headphones. Yes, it is much more convenient than wired headphonesbecause No wires and does not interfere with the use of at the same time the phone and listen to music. Although, for convenience you need to pay - regularly charge not only the phone, but also headphones to it.

The difficulty in choosing wireless headphones is that there are several profiles for transferring music from the phone to the headphones on Bluetooth. Can assume that it different languages. When you connect headphones to the phone, these profiles are reconcilized, and only those that are supported simultaneously with the phone and headphones are used. It is for this reason that you may notice the difference in playing music with one headphones that you connect to different phones - It all depends on the profile. Today, the highest quality is the APTX profile. Remember that it should support both the phone and headphones. Unfortunately, not all phones are used, even modern flagships may not know about it. A sad example is a Google Pixel.

Solution 1: Carefully examine the supported phone and headphone profiles.

Before buying wireless headphones or phone, read in reviews on sites or instructions for the device, which profiles wireless transmission They support data. If you want to get the highest possible quality, make sure that both devices support APTX profile.

Solution 2: Check the battery charge level

Sometimes wireless headphones can start worse to work with a low battery charge. Fully charge headphones and phone to get best quality Sound.

Solution 3: Always update your phone

We live in a complex world, and the production of electronics is a double difficulty level for any manufacturer. Sometimes, after the release of a new phone, not all errors software Eliminated. So regularly check whether software update Your phone. In some cases, timely update can correct errors in wireless communication And the quality of music transfer can improve significantly.

And where is Bass?

Quite often, I ask the same question: "Why did I bought expensive headphones, and they play bad?"

I have an answer to this question, but you may not like it.

So, let's start with the fact that every person hears the sound in its own way. It depends on both the physical structure and the shape of your ear shell, the ear canal and the sensitivity of the eardrum, and on which sound you are used to listening, and what kind of sound you would like to hear.

Professional and expensive headphones manufacturers try to do so that they, if possible, all audible sound frequencies played with the same volume. But even if the manufacturer succeeds - your hearing is not so clear. Each person perceives different frequencies with different volume. And even more so, in men and women, there are different sensitivity to different frequencies of sound, for example, women's ear perceives high frequencies in women, because Evolutionarily they are predisposed to hear a child's crying. Men are better perceived by mid frequencies.

It is for this reason that there are so many manufacturers of headphones on the market today, and each manufacturer has a large line of a variety of headphones, both by the forms of the factor and on the configuration of their sound. And then I can advise you only one thing - you need to listen to the headphones yourself before buying.

Therefore, even professional expensive headphones may seem bad if you are accustomed to music, where many bass, or medium, or high frequencies. You want and accustomed to listen to the vocabulary music, and there is nothing wrong with that. You just need to consider it when buying new headphones. Remember, you need not expensive headphones, but those that like you like the most and not always correlated with the price.

Solutions 1: Read a lot of reviews

If you decide to buy some headphones - look not alone and not two reviews on them, and more. It is desirable to find everything. Because the whole point of review is how headphones evaluate special person. I think you have already noticed that on one site a journalist or blogger praises headphones, and on the other hand, they write that they are bad. And you probably think that those who praise - sold? But in fact, everything is more complicated - journalists, too, people and rumor they have different. Therefore, one sound of headphones can appeal, and there is no other. That is why you need to read all the available reviews, and repel from the opinion of the majority. So you minimize the risk of buying bad headphones.

Solution 2: Use Equalizer

This is a simple advice, however, in very many cases he can solve your problem. If you use the phone as a sound source - use the equalizer if you do not like the sound in headphones without it. But remember that the equalizer must be tuned carefully. Try slightly strengthening or loosen the sound of those frequencies as you like more. But do it gradually. After each change, listen to music, at least a few minutes. Listen to different songs, different performers, different genres. If the settings in general worked well - continue to configure further. And so every time. Only so you can configure music under your ear and your headphones so as not to spoil her sound, but improve. And remember that when changing headphones, you will have to configure the equalizer from the very beginning.

By the way, the good headphones are good, so it is a more even response. So, it will be easier for you to set up an equalizer for yourself. But this rule is also not always working, and before buying even expensive headphones, try to find their accommodation Chart, to approximately imagine how they will sound.

Currently it is proposed to choose from many species of various Blutuses of headphones, headset and speakers receiving sound through this protocol. Very often when buying inexpensive headphones There are problems with sound quality, namely stuttering sound and its delay. There are several ways to solve this problem ...

The main problem of stuttering Blutuz headphones is the quality of their manufacture and incompatibility of standards. The problem may be in a low-sensitive antenna and the power of the processor built-in to the device. And, accordingly, no power grip can be on the transmitting device: computer, tablet, telephone and Bluetooth module inserted in USB port PC, as well as the incompatibility of Bluetooth version.

It is still noticed that in the room the headphones work well, and on the street there is constantly interrupted. In the room where there are walls close, the signal is reflected from the walls and falls into the receiver wireless headset And everything works fine. Where there are no walls, the sound is lost.

It is noted that the same headphones on one smartphone work normally, and on the other they are stuttering. And it happens so that everything was fine, but after installation new program Or update the application, the sound is synchronized. It is also observed when the screen is turned off mobile device Or when switching the phone to the locked mode.

Particularly often occurring sound when installing, deleting or copy files from a flash drive to a USB flash drive. Since the system resources are used at this moment. All this worsens the sound quality in headphones. If this happens, then it must be borne in mind that the power of the processor lacks the sound and transmission to the Blutuz protocol.

Clean, loud noise without wires.

Chief Council, before buying a Blutuz headset, check the quality of playing it, as they say "without departing from the box office", immediately in the store. If this is not possible, keep the check and packing the goods, to return it back to the point of sale.

What if the product is not possible to return to the store?

How to solve sound stuttering in Bluetooth headphones?

1. If you have a PC and USB, the Bloom module is inserted into the rear port of the computer. Move the USB Bluetooth on the front side of the PC. Better to buy a USB hub on the wire, lift it higher and stack the USB Bluetooth module into it. If the Blutuz adapter is old, then it is better to change it to a newer and modern one.

Updating Driver Blutuz in Windows Task Manager.

2. If you have a PC, change the drivers in the device manager to "sound and game devices" and in the Bluetooth subsection. Here you have to start searching drivers windows tools. For this, select "Update".

If it did not help, then you must try to put different versions Drivers and check, somehow can earn.

When synchronizing with a PC, the Bluetooth headphone models may have compatibility problems with Windows drivers.

3. Outside on the street to exclude interruptions in music playback, put your smartphone as close as possible to headphones. Shoot your smartphone from pockets in your pocket, and the higher the headphones, the better. Or put it in the upper, inner pocket jacket. Do not use headphones in the cold.

4. With the player settings or in the settings of the audio device on the PC, lower the quality of the playback of the audio stream, i.e. If you listen to music in 320kbbit / s or more, try the sound no more than 128kbbit / s. Audio MP3 files must be recorded with a low bit rate.

If you have a laptop with weak speakers and when playing the next volume of the volume of the built-in speakers, it is not enough for a comfortable view, you can use tips to increase the volume on a laptop or telephone.

5. Make the BT mode on the transmitting device "visible to all". In this mode, the system loads less processor.

6. The devices are closer to each other for a few seconds or put the sound playing in the player or youtube pause, it is necessary to synchronize devices. To complete sound synchronization, you may need a few seconds.

7.The Android 6.0 in the settings there is an item: "application permissions", in it "Transmission via Bluetooth". Here you need to remove all the ticks, except for the "volume". Here we click: "Changing settings" and select the item "Do not disable".

8. Android Android OS can be dispersed through special programs Type: Setcpu, Tasker, Antutu CPU, TEGRAK, Overclock and others. Changing OS operation parameters is made in the "Performance" section. You need to change the following values: Government in "Perfomance", Scheduler in "CFQ". Even advise such a solution: Installing Kernel Adiutor C CPU Governor to Ondemand (+ "Apply On Boot" for convenience).

9. You can use the load on the system using a special software. There is such a DROIDWALL program that can control Internet access each application OS android. To reduce the load on the processor, prohibit the applications at the moment in this time. You can do it through the program menu.

10. Put the antenna in the headphone housing or columns Bloom. If you remove the housing cover, then the feet should be a kite-shaped path. To this track, the craftsmen solder a piece of copper wire centimeter 4-5. After that, the signal quality rises and the sound stops stuttering.

Video: My perfect Bluetooth wireless headphones.

Video: 5 Bluetooth headphones. Sending from China.

11. The load of the processor on the PC can also be disabling the microphone on the Bloom headset. To do this, you need to go into the control panel \u003d\u003e sound \u003d\u003e record \u003d\u003e microphone \u003d\u003e properties \u003d\u003e Listen \u003d\u003e Remove the checkbox with "Listen to this device" And restart the computer.

12. Performances from other devices strongly affect the quality of the compound. If a wireless column Or SAB stands next to the router, a TV, a computer, microwave and other radio interference sources, then it must be moved.

13. The trouble-charged battery is the reason for the lack of power of the processor of the device Blutuz.

14. The unaware models of Blutuz headsets may not be compatible with new smartphones and vice versa. This is the main reason for the instability and stuttering music. Therefore, before buying a wireless device, you must always check whether these two mobile devices will be well available.

More information about the Bluetooth protocol can be read in the article on Habrahabr.ru. There is analyzed the process of loss of signal with screenshots and graphs.

Analysis of human body impact on the transmission power of the audio data via Bluetooth protocol.

In the picture, it is shown that from the dump it is seen, the BitPool value for this portion of traffic is 48, but it cost me to close the way from the laptop to the column, as the BitPool value began to decline, accompanied by interrupts and clicks.

After the BitPool value settled at level 30, the clicks are disappeared, the playback of the audio has become more continuous. Everything indicated that the codec was performed by auto-adjustment, noting the degradation of the quality of the signal.

But did I really contribute such a significant attenuation? Well, time to look at the indication schedule for the power level of the received signal.

The world stepped into a wireless era. Keyboards and mice, data transmission, Internet access - everything has already left the cables for a long time. However, there are still certain things that literally keep us in this terrible world of wires. And besides the most obvious - for example, charger, remain and less noticeable, but far from less important accessories are headphones. After all, you will agree, not everyone falls on the temper every time to think about where and how to "push" the wire only to go out. And when sports about the headphones, it is generally better not to remember. Why so there - did you never annoy you that they should be removed to stand because of the computer? Therefore, for many, the issue of buying wireless headphones is quite acute. It would seem that everything for this is - at the moment this market is already saturated enough to find a suitable option. But, unfortunately, there are a certain number of problems. After all, in fact bluetooth headphones did not make significant high-quality jerks from the very moment of their appearance.

But on a certain day, such a question became before me. Being confident in the fact that the current year did the technology, I quickly chose my gadget - Jabra Halo 2. [Lyrical retreat]: Yes, we can say that Jabra Halo 2 is not an indicator and a bad example. However, not every average buyer can afford an advanced technique like or - although it is possible that they will be deprived of all the following flaws. Moreover, even Jabra Halo 2 budget can not be called in no way - I will remind you that for the same one thousand hryvnia you can buy quite serious wired headphones [End of lyrical retreat]. And after almost a year since the start of operation, it is ready to tell about all aspects of life with Bluetooth middle class headphones.

The first minus surfaced almost immediately - as soon as the phone turns out in pocket jeans, the signal begins to get lost. We had to put the phone in the pocket of the jacket, the jacket, or in the bag (however, it turned out that the connection is much better in the right pocket of jeans, but it did not solve it completely). And in general, the interruption of sound is the most common problem. Interference can catch you literally at any time, and they are so nasty that you start to unwittingly turn the phone in your pocket in the search for "optimal position." Moreover, it happens that the environment affects the environment - near the local stadium, for example, interference is observed almost always. Also, the gap will pursue you in the first minute or two after connecting to the device.

Second problem - sound quality. Yes, in fact, Bluetooth headphones sound perfectly - but with a connected wire. On the wireless connection, they are suitable except for listening to podcasts, radio, watching rollers with YouTube and communicating with friends. Music connoisseurs will be increditious to turn her nose (and fairly), although not particularly proper users (like me) and those will be satisfied.

And it is logical that a little lame speed of work. From the sound itself until its playback in headphones, there is some time within a second. And from the very first day, the user will notice that before you start playing the sound, the headphones will turn on the barely noticeable noise (on the background of the music, it is completely lost), and when reproduction is over - this noise will disappear, while with a sufficiently sharp click, which on high level Volume can noticeably hit the ears. However, it is possible to get used enough to this.

And at least these three minuses are already predetermined by the fate of wireless headphones. There is no practical meaning in them. It can be seen that this direction is gradually developing, but specifically at the moment - this is a waste of money. It seems that the market exists in order for it to be at all - and the user still finds. Believe me, freedom from the wires are not worth all the problems described above. Although there are positive moments with such headphones, but my advice to you: either buy expensive Bluetooth headphones, or take good and wired.

Good day.

To most home computers (and laptops) columns or headphones are connected (sometimes both). Quite often, in addition to the main sound, the columns begin to lose and all sorts of outsiders: the noise of the scrolling mouse (very frequent problem), various cracks, trembling, sometimes light whistle.

In general, this question is quite multifaceted - dozens of reasons for the appearance of extraneous noises can be ... In this article I want to indicate only the most common causes, because of which foreign sounds appear in headphones (and columns).

Cause # 1 - Problem with Cable for Connection

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

a damaged (interrupted) cable that connects columns with a computer (see Fig. 1). By the way, in this case it is also often possible to observe such a problem: there is a sound in one column (or headphone), and there is no other. It is also worth noting that the interrupted cable is not always visible to the eye, sometimes you need to install headphones to another device and test to get to the truth;
poor contact between the nest network card PC and headphone plug. By the way, it often helps to simply remove and insert a plug of the socket or turn it clockwise (counterclockwise) arrows at a certain angle;
unlined cable. When he begins to hang out from draft, pets, etc. - foreign sounds begin to appear. In this case, the wire can be attached to the table (for example) by the usual tape.

By the way, I also observed such a picture: if the cable for connecting the speakers is too long - extraneous noises may appear (usually hardly distinguishable, but still annoying). With a decrease in the length of the wire - noises disappear. If your columns are very close to the PC - it is possible to try to change the length of the cord (especially if you use some extension cords ...).

In any case, before starting trouble finding problems - make sure that with the "iron" (speakers, cable, plug, etc.) is all right. To check them, it is enough to use another PC (laptop, TV, etc. devices).

Cause No. 2 - Problem with Drivers

Because of the problems with the drivers can be anything! Most often, if the drivers are not installed, you will not have any sound at all. But sometimes, when not those drivers were installed - it can not be observed at all proper work Devices (sound card) and therefore different noise appear.

Problems of this nature also often appear after reinstalling or windows updates. By the way, Windows itself often reports that problems are observed with the drivers ...

To check whether everything is in order with the drivers, you need to open Device Manager (Control Panel \\ Equipment and Sound \\ Device Manager - See Fig. 2).

In the Device Manager, you need to open the tab " Audio inputs and audio outputs"(See Fig. 3). If yellow and red will be displayed in this tab in front of the devices exclamation signs - Therefore, conflicts and serious problems with drivers are not observed.

Cause # 3 - Sound Settings

Frequently, one or two ticks in the sound settings can completely change the purity and sound quality. Quite often, interference in sound can be observed due to the included PC Beer and linear input (and so units, depending on the configuration of your PC).

To set the sound - go to Control Panel \\ Equipment and Sound and open the " Volume setting"(As in Fig. 4).

In the "Levels" tab must be the cherished "PC Beer", "CD", " Linear input"And pr. (See Fig. 6). Digit the signal level (volume) of these devices to a minimum, then save the settings and check the sound quality. Sometimes after such entered settings - the sound changes dramatically!

Cause No. 4: Volume and Quality of Columns

Often hissing and cracking in columns and headphones appears when their volume tends to the maximum (noise appears on some when the volume becomes above 50%).

Especially often this happens with inexpensive column models, many call this effect "jitter". Please note: maybe the reason is just in it - the volume on the columns is added almost to the maximum, and in the Windows itself, it is reduced to a minimum. In this case, simply adjust the volume.

In general, it is almost impossible to get rid of the "jitter" effect at high volume (of course, without replacing the speakers to more powerful) ...

Reason No. 5: Power Supplies

Sometimes the reason for which noise appears in the headphones - is power Scheme (This recommendation for laptop users)!

The fact is that if the power supply scheme is set in the mode of energy efficiency (or balance) - maybe a sound map simply lacks nutrition - because of this, extraneous noises are observed.

Output simple: go to Control Panel \\ System and Security \\ Power Supplies - and choose the mode " High performance"(This mode is usually hidden in the Advanced tab, see Fig. 7). After that, you also need to connect the laptop to the power supply network, and then check the sound.

Cause No. 6: Grounding

The point here is that the computer case (yes and the columns often also passes through itself electrical signals. For this reason, various outsiders in columns may appear.

In order to exclude this problem - Very often helps one simple reception: connect the computer case and the battery with a regular cable (cord). The benefit that the heating battery is almost in every room where the computer is. If the reason was in the ground - this method in most cases eliminates interference.

Mouse Noise when scrolling Pages

Among the types of noise, such an extraneous sound prevails - like the sound of the mouse when it is scrolling. Sometimes he annoys so much - that many users have to work at all without sound (until the problem is eliminated) ...

There may be such noise for various reasons, it is not always easy to install. But there are a number of solutions to try:

replacement mouse to a new one;
replacement USB mice On PS / 2, the mouse (by the way, many PS / 2 mouse is connected via a USB adapter - simply remove the adapter and connect directly to PS / 2 connector. Often the problem in this case disappears);
replacement wired mouse on wireless (and on the contrary);
try to connect the mouse to another USB port;
installing an external sound card.

PS.

In addition to the above, the column may begin to the phoning in cases:

before a call mobile phone (especially if he lies close to them);
if the speakers are too close to the printer, monitor, etc. Technique.

On this problem, everything is all. I would be grateful for constructive additions. Good job 🙂
