Noise in wireless headphones. How to remove noise from headphones on a computer? Wireless headphones for computer with microphone
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 the connection between the PC sound card and the device for sound reproduction is poor. 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, 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 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 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.
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: mouse scrolling noise (a very common problem), various crackling sounds, trembling, and sometimes a slight whistle.
In general, this question is quite multifaceted - there can be dozens of reasons for the appearance of extraneous noise... In this article I want to point out only the most common reasons why extraneous sounds appear in headphones (and speakers).
Reason #1 - problem with the connection cable
One of the most common reasons for the appearance of extraneous noise and sounds is poor contact between the computer's sound card and the sound source (speakers, headphones, etc.). Most often, this happens due to:
- damaged (broken) cable that connects the speakers to the computer (see Fig. 1). By the way, in this case you can also often observe the following problem: there is sound in one speaker (or headphone), but not in the other. It is also worth noting that a broken cable is not always visible to the eye; sometimes you need to install headphones to another device and test it to get to the bottom of the truth;
- poor contact between the PC network card socket and the headphone plug. By the way, very often it helps to simply remove and insert the plug from the socket or turn it clockwise (counterclockwise) to a certain angle;
- loose cable. When it starts to hang out from a draft, pets, etc., extraneous sounds begin to appear. In this case, the wire can be attached to the table (for example) with regular tape.
By the way, I also observed the following picture: if the cable for connecting the speakers is too long, extraneous noise may appear (usually subtle, but still annoying). When the length of the wire was reduced, the noise disappeared. If your speakers are very close to your PC, it might be worth trying to change the length of the cord (especially if you use some extension cords...).
In any case, before you start looking for problems, make sure that everything is in order with the hardware (speakers, cable, plug, etc.). To check them, just use another PC (laptop, TV, etc.).
Reason #2 - driver problem
Anything can happen due to driver problems! Most often, if the drivers are not installed, you will have no sound at all. But sometimes, when the wrong drivers were installed, the device (sound card) may not work correctly and therefore various noises appear.
Problems of this nature also often appear after reinstalling or updating Windows. By the way, Windows itself very often reports that there are problems with drivers...
To check if everything is ok with the drivers, you need to open device Manager (Control Panel\Hardware and Sound\Device Manager- see fig. 2).
In Device Manager you need to open the " Audio inputs and outputs"(see Fig. 3). If yellow and red exclamation marks are not displayed in this tab next to the devices, it means that there are no conflicts or serious problems with the drivers.
Reason #3 - sound settings
Quite often, one or two ticks in the sound settings can completely change the clarity and quality of the sound. Quite often, noise in the sound can be observed due to the inclusion of PC Beer and the line input (and other things, depending on the configuration of your PC).
To configure the sound, go to Control Panel\Hardware and Sound and open the tab " Volume settings"(as in Fig. 4).
In the “Levels” tab there should be the treasured “PC Beer”, “CD”, “Line input”, etc. (see Fig. 6). Reduce the signal level (volume) of these devices to a minimum, then save the settings and check the sound quality. Sometimes after these settings are entered, the sound changes dramatically!

Reason #4: Speaker volume and quality
Often, hissing and crackling in speakers and headphones appears when their volume reaches maximum (on some, noise appears when the volume rises above 50%).
This happens especially often with inexpensive 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) passes electrical signals through itself. For this reason, various extraneous sounds may appear in the speakers.
To eliminate this problem, one simple trick often helps: connect the computer case and the battery with a regular cable (cord). Fortunately, there is a heating radiator in almost every room where a computer is located. If the reason was grounding, this method in most cases eliminates interference.
Mouse noise when scrolling the page
Among the types of noise, the prevailing extraneous sound is 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:
- replacing the mouse with a new one;
- replacing a USB mouse with 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);
- replacing a wired mouse with a wireless one (and vice versa);
- try connecting the mouse to a different USB port;
- installing an external sound card.

PS
In addition to all of the above, speakers may begin to produce noise in the following cases:
- before a mobile phone rings (especially if it is close to them);
- if the speakers are too close to the printer, monitor, or other equipment.
That's all I have on this issue. I would be grateful for constructive additions. Good job 🙂
Probably everyone has encountered this problem - people close to you are sleeping around, but you want to listen to something while sitting at the computer. Or just watch a video with sound. It seems that you don’t need a high-quality audio system for this, plug the headphones into the front jack of the computer and have fun. It wasn't like that. Greetings, dear friends. My story began with the fact that I changed my personal computer case. The victim of my adventures was the AirTone MC-6010. I've been eyeing it for a long time, big, beautiful, well made... I spat and bought it. How much can you poison your soul? And satisfied with the barrel of honey, the bear wandered home... But the bear did not rejoice for long. There was also a fly in the ointment here. Someone stepped on our bear's ear. I connect headphones to the front (front) panel connector, and I hear a beeping sound from them. I move the mouse and the squeaks change. I scroll through the page with the wheel and it changes too. And this sound is so annoying that it was decided to change something.
The first thing I did was look for information on the Internet. I refused advice to update the BIOS, and realized that manual therapy was not enough. Apparently something was done with the layout of the ground. We'll open it. Having decided on this idea, I abandoned it for a long, long time. I just didn’t want to go through all the trouble of stirring things up. But by chance, I recently decided to check my friend’s motherboard, and shook up everything that was in my system unit. Well, I decided to figure out what was going on for the company.
So, we are faced with the first task. Disassemble the case and get to the insides of the front connector panel. Ok, let's get started. Having disassembled half of the body, removing the door opening mechanism and much more, I once again made sure that I had not noticed any fasteners somewhere. And so it turned out. So, our panel with connectors is attached: a self-tapping screw in the front part, access to which is through a rectangular slot in the metal from below. Two screws in the middle. And attention (!!!) there is another self-tapping screw behind the far latch under the wiring harness. It is this wiring harness that prevents it from being seen. After this, move the 3 latches with your hands and pull the top panel up and towards you. It will resist a little, since there are 2 more non-locking latches installed in the front part. Under our pressure, they also carefully emerge from their seats without any harm.
Hurray, the hardest part is over! I hope... We see a neatly made case in which everything is attached. We take a screwdriver and unscrew the two bolts on the sides that hold it...
The first thought is wow, there’s so much here... But my hands are already trying to move on) I must say that I liked the implementation. Everything is done neatly, everything is detachable for ease of use. Well, let's continue. So, we are looking for land. To do this, we need a pinout diagram for the HD audio connector and a tester. The first one is easily found on the Internet, the second one can be found at home. Well, or if you’re really unlucky, then in any radio store. Here is the first one from the list:
Having found the wire we need, we call it with a tester. I didn’t even have to do this, the color marking of the wires was done very carefully, and I had no problems finding the mating contact on the connection block to the panel. In the picture below it is highlighted in red.
Well, of course, the cause of all the problems is immediately visible. The pins of the ground buses of the audio path and USB/E-Sata ports were soldered together. We turn it over and make sure that the earth diverges into different wire harnesses. Of course, our USB ports produce a lot of noise, which is amplified by the resulting ground loop. So it needs to be cut. Scalpel please! Why not? Well... then a paper knife! (if you don’t have it, you can use the regular one, but it will be a little less convenient). We're cutting! Stop. What exactly are we going to cut? Well, I'm in a hurry again. We plug an empty plug into the audio connector and find where the ground is connected to it. In the picture above I marked it in blue.
What would be the best way to do it? Cut it off and connect directly to the wire? Then the panel will become one-piece. What if... After measuring the dimensions, I came to the conclusion that there is more than enough space in this case. Then we carefully isolate these pins from the common ground polygon, and connect them to each other with jumpers from a piece of wire. Now let's cut!
Each pin pad is connected to a common polygon by four thin jumpers at the corners. Carefully cut them, to be sure, ringing them with a tester for lack of contact. Ready! Now we need to connect them to the main ground pin. How? You can use any wire that suits your aesthetic needs. Preferably, of course, without extremes. For some reason, I immediately imagine a thin ligature of an engraved pattern on the surface of the insulation... Ah! Let's continue! Well, I didn’t find the wire right away. From computer power supplies it is a bit thick, from twisted pair cables it is thin and brittle. No, hunting for something more civil. After rummaging through the bins, I found this work, probably from Soviet times. The next generation will no longer understand where he came from. I barely caught it myself
This is an audio cable that connected the optical drive to the motherboard in older computers. Just right! Cut off the black wires. Let's see. Stranded, tinned copper. It couldn't come at a better time. Great! We take a soldering iron, a desoldering pump, and get to work. We separate the required pin from the other three with which it is filled with solder. We complete the job with a knife, cutting the contact strips going to the common ground. In this place, be careful, there is a path next to the pin on the left, which has nothing to do with our showdown. You must be careful not to damage it. We use a tester to check the work done and carefully solder two jumpers from the chosen wire.
Rejoicing at the completion of the work, I assemble the entire case and turn on the computer. Hooray! No more noise in the headphones! True, there is no sound either... I collected it, of course. But he did everything carefully, it seemed like there was nowhere to make a mistake! After digging through the driver settings, I found out that not everything is so bad. The panel works, but it does not detect that a device is connected to it. If you disable the detection function, the sound goes through the headphones. Internet again? Are looking for! It turns out that the panel I got was not HD Audio, but simply AC 97. After reading the information, I learned that this is exactly what distinguishes them. The ability to determine that a device has been connected. Not good. Having searched a bunch of forums, I still haven’t found information on what algorithm is used to determine it. But the pinout diagram, that is, of both standards. So, let's go looking. We disassemble the case again, this time removing only the top panel. By the way, I managed to put the self-tapping screw that I was screwing through a rectangular slot in the metal in the wrong place, leaving marks on the board. Be careful, don't repeat my mistakes.
Having reached the board again and armed with a tester, I begin to make calls... Well, of course! How did I not notice right away! One of the four pins combined together also goes into the same wiring harness and belongs to HD Audio. As they say in the pinout, this is a certain “–ACZ_DET”. So it becomes clear what kind of contact this is. He is responsible for determining the type of connected panel. Again, take the soldering iron, desoldering pump and knife. We also separate it from the other pins, isolate it from the ground polygon and combine it with the HD Audio ground pin.
Modern people often use devices such as headphones and a microphone. They facilitate communication on the Internet, allowing you not only to hear, but also to respond to another user. Connecting all the necessary devices to your computer will not be difficult, the main thing is not to forget to make all the necessary settings. However, despite the friendly interface, sometimes strange problems arise. How to remove the noise and hiss on your headphones that occurs when connected to a computer? It will be useful for everyone to know about this information.
Why do my headphones hiss? Information about their internal structure will help us answer this question. Clicks in the headphones, as well as incomprehensible hissing, occur quite often. This phenomenon may be temporary or permanent. There may be several reasons for this behavior. Determining the source of problems can be a real problem for an unprepared person. For example, headphones may hiss due to incorrect connection settings, but this can also be caused by faulty contacts. Let's look at the most common sources of noise and ways to eliminate them.
One of the main reasons affecting the quality of the reproduced sound can be the sound card. The operating system cannot transmit signals correctly, as a result of which the sound begins to jump, break, hiss and crackle. In this situation, there is only one thing you can do - replace the faulty computer part. Only this will get rid of unpleasant sounds.
Ground faults
This problem bothers users less often than others. The conversation is about grounding of sockets, used to power devices from the electrical network. Because of this, various noises, clicks and crackles may occur in the headphones.
This does not apply only to laptops, since their boards are often grounded.
Extraneous noise in this case is caused by internal failures of the device. The owner will have to contact a service center or ignore the problems. For other people, the solution to the problem will be to ground the outlet.
The wire
What other reasons can cause such an unpleasant effect when connected to a computer? Much in this matter will depend on the manufacturing company that manufactured the specific headphone model. Today there are two main types: wireless and wired headsets, this division is of great importance. Extraneous sounds mainly occur in cable devices connected using a plug. What is the source of the problem? Damage or stretching of the cable's copper core can cause noise and sound surges.
Cable malfunctions often occur in headphones on iPhones, since their wires are degradable and easily break.
A damaged wire transmits distorted signals to the sound card, which ultimately affects the sound. What to do if your phone headphones wheeze? You can fix the damage using removing damaged wire fragment or buying new headphones.
USB devices
Strange sounds may appear after connecting additional devices to the USB connector. So, the source of problems can be the mouse or even the keyboard. In this case, you will hear a clicking sound every time you press a key. This happens due to the following reasons.
when transmitting information. The situation can be corrected by switching the plug to an adjacent port. You can find a suitable splitter, repair old connection connectors, or switch to wireless devices.
USB splitter
Sound source problem
Headphones quite often fail due to violations of operating rules. However, problems may also be hidden in the main sound source. For example, quite rarely, but it still happens driver error. Software damage or operating system failures cause problems that cause noise and rattling. You can identify the problem by connecting different headsets; if they all produce the same result - an unpleasant hum or hiss, then the problem is in the device driver. Handle your devices with care and follow the operating instructions.
No one will be happy with noise, crackling and other extraneous sounds in the speakers when you want to enjoy music, watch an interesting movie or chat with friends via the Internet. All this cannot be done if the sound quality in the headphones is poor. Buy philips headphones - the best way to get quality ones. How to get rid of this annoying interference? First, let's look at the reasons for their appearance.
Poor quality integrated sound card
Most users use a sound card integrated into the motherboard. Only a few buy a separate board, especially an external one, to reproduce sound.
Motherboard manufacturers strive to minimize production costs, since most users do not pay enough attention to sound quality. Therefore, manufacturers limit themselves to only a couple of dollars for wiring an integrated sound board.
There is a serious flaw in this solution. High frequencies of neighboring microcircuits generate electromagnetic interference, which, although it does not affect the digital part of the audio subsystem, can cause noise in the analog subsystem.
Cheap separate sound cards that connect to the PCI connector of the motherboard have the same problems. True, to a lesser extent due to greater distance from other microcircuits.
Lack of grounding makes the problem worse
Not every home has grounded electrical outlets. If there is no ground connection, it will worsen the sound problem by increasing the noise. And if we talk about a laptop, then the presence of grounding in the electrical network does not reduce the problem at all, due to the design features of laptop computers.
Noise when connecting devices to USB
It often happens that extraneous noises and sounds are not even noticeable. But as soon as you connect an external hard drive, keyboard or mouse to the USB connector, noise immediately appears in the speakers. Moreover, in such cases the noise is very specific:
- when connecting a hard drive, a crackling sound is heard when copying data;
- when connecting a mouse, monotonous noises are heard when the manipulator moves;
- When connecting a keyboard, there is a clicking sound when pressing keys.
Typically, this problem is associated with the audio and USB chips being very close together. As a result, active transfer of information via the USB interface negatively affects the sound.
How to get rid of extraneous noise
In most cases, it is enough to connect the ground to the computer. But this method is not applicable for laptops; only an external USB audio card will help.
Use the digital audio output from your audio system. This is guaranteed to save you from extraneous noise. True, it requires acoustics with its own digital-to-analog converter. Another drawback is that most of these systems do not have a headphone output, which limits their use.
Buy a high-quality separate PCI sound card, or, as an option, a normal USB audio card. On the one hand, it is expensive, on the other, it is extremely effective. There will be no noise, and in combination with good headphones or a speaker system, the sound quality will be excellent. This method is especially relevant if you are going to not only listen, but also record.
