There's some noise in the headphones. Hissing, noise, crackling and other extraneous sound in speakers and headphones - how to find and eliminate the cause? Noise when connecting USB devices

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 - best way get quality How to get rid of these annoying interferences? First, let's look at the reasons for their appearance.

Poor quality integrated sound card

Most users use a sound card integrated into 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 you just need to connect it to a USB connector external hard disk, keyboard or mouse, and noise immediately appears in the speakers. Moreover, in such cases the noise is very specific:

when connecting 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 sound PCI card, 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, but in combination with good headphones or sound system The sound quality will be excellent. This method is especially relevant if you are going to not only listen, but also record.

Using headphones connected to a computer, it is convenient to communicate in video conference mode over the network. In addition, this simple accessory allows you to listen to your favorite music without disturbing your household. Also, this gadget is an indispensable attribute for gamers, both amateurs and professionals. But there are situations when pleasant communication, listening to music, watching videos or an intense game begin to be interfered with by incomprehensible noise effects that are very annoying. In this case, the user is faced with the question of how to remove noise from headphones on a computer, the answer to which can be found in this material.

Main causes of the problem

To ensure that working with sound reproduction on a computer through a headset does not cause trouble, you need to have information about the main causes of poor sound and be able to deal with them. So, the main signs that will help identify a malfunction are the following factors.

Hissing noise in headphones may indicate damage to the cable connection. When you hear a crackling sound, or the sound is played only in one mini-speaker, it is also likely that the connection between the device and the PC is broken.
If the headphones distort the sound, it is possible that The computer sound card is not working correctly. This reason is also indicated by the following signs: broken sound, wheezing and other noises.
The hum in the headphones indicates grounding problem.
If gadgets are constantly buzzing, then the likely cause may be those connected to the PC low quality multimedia speakers.
Connected to a computer external USB devices may cause a monotonous background or clicking sound in the headset.
Extremely rare sound interference, but more often silence in headphones is a sign incorrect driver operation devices on PC.
A wide range of third-party sound effects are triggered incorrect sound settings in the OS Windows 10 or version lower (7/8/1).

How to find and fix a noise problem in a computer headset

Finding the cause of interference in headphones on a computer and eliminating it is quite difficult, since it is impossible to predict what measures will correct the situation. Therefore it is necessary sort through all potential sources of third-party noise in order, starting with the most common and obvious.

Monitoring cable integrity and correct connection

With a wired headset, the most obvious and common cause of the problem in question is poor connection quality. With prolonged use, the wire may break, then the headphones hiss instead of the expected sound reproduction. So, most often, damage to the integrity of the wiring occurs at the base of mini-speakers inserted into the ears, or near the connecting plug. To diagnose this malfunction you need:

carefully check the cable along its entire length for integrity of the braid;
make sure by touch that there are no tubercles or gaps inside;
Check the tightness of the plug into the computer connector.

Note! With certain skills, a damaged cable can be repaired. But this requires experience in delicate work and basic electrical knowledge. Therefore, it is easier to use other headphones.

Checking the health of the sound card

If everything is in order with the integrity of the headphones, it is recommended to use the operating system on a PC carry out the procedure: “Troubleshooting sound problems”(for OS version 10) or “Troubleshooting problems with sound playback” (in other versions of the system).

You can check whether your computer’s sound reproduction is working correctly using the “Device Manager” system tool. Near “Sound and video devices” and next to unlockable objects there should be no yellow or red exclamation mark icons. Otherwise, through the “Properties” mode, you should look at information about the state of the problematic object responsible for sound.

Note! The system wizard will help you carry out diagnostics, sequentially offer several options for problems and tell you how to fix them. Using the service, you can identify a faulty audio card. The wizard will report the following: “Could not resolve the problem? Seek help from a specialist."

As an option to solve a sound problem in the event of a breakdown of the audio card, you can connect it to a computer external USB sound card and connect the headset to it along with other audio devices. How to connect to a PC correctly - in the article ““.

Troubleshooting Grounding Problems

Computers and peripherals, including headphones, are very sensitive to the quality of power supply - connecting such equipment to an ungrounded outlet is fraught with various kinds of operational interference and breakdowns. If a grounding problem is suspected, it is recommended purchase a surge protector or UPS, and use this device when connecting equipment to power.

Checking the variant of interference from speakers

If both multimedia speakers and a headset are connected to the front panel of the PC, then the headphones are humming precisely because of the interference created by the speakers. Budget-class audio peripherals, as a rule, do not differ in build quality, and can create electrical background disturbances, to which the headphones react “noisily”. To verify/refute suspicion, you need to disable multimedia speakers.

Eliminating interference from third-party USB peripherals

Any external USB device connected to the PC will also can create electromagnetic waves, which reach the headphones through the computer and are reproduced in the form of third-party noise that interferes with comfortable listening.

Advice! To find the “culprit”, with headphones on, you should take turns disconnecting one device after another from the PC. If, after disconnecting all external peripherals, the devices are still noisy, then the source of the problem is somewhere else, and you should continue the search.

Analysis of the correctness of drivers and the correct sound settings on the PC

Headset drivers latest versions Windows OS is installed automatically. As a result system failures or virus attacks The sound driver may be damaged, resulting in skipped sound. In addition, point out incorrect operation This may occur in situations where the mini-speakers in the ears either crackle or wheeze. Sometimes users note the effect of “hearing myself” like an echo.

There are several ways to correct the situation, each of which should be tried.

The influence of power supply mode on noise in headphones

On a laptop, many users, in order to save battery power, configure the appropriate power consumption mode. For a headset with such a design, it can be elementary not enough tension, and the sound can be quiet at best, but is often accompanied by extraneous noise. This problem can be solved by reconfiguring the power supply circuit from economical to more efficient.

Wired headset malfunction

The noise source may be. This hypothesis can be verified or refuted using connecting the headset to another computer and/or laptop. An alternative way to check is on an iPhone, tablet or Android phone.

Important! If the headphones continue to make noise when working with another device, then it is advisable to replace such a gadget.

Possible sound problems on wireless headphones

Most wireless devices operate via Bluetooth. If such headphones reproduce sound perfectly from mobile devices, then when paired with a laptop it is rare, but there may be problems: lack of bass, squeaking and other noise. The fact is that when you connect headphones to Windows via Bluetooth, two audio devices are created - a headset and stereo headphones.

Important! You should check the sound settings to select the main audio device - the checkbox should be set to stereo headphones. Otherwise, you need to reconfigure the selection.

There is a big difference in sound quality between a headset and stereo headphones. If the sound output is assigned correctly, then there will be no significant differences from playback with mobile device will not be observed.

Using headphones is not a completely safe activity. In some cases, they can pose a risk to health and even life. Read below about what not to do.

Excessive listening to music through a headset at high volume, both temporary and permanent.
Also on the auditory organs negative influence provides poor sound quality.
Using a headset while walking or driving can result in injury and injury in the event of various road accidents, since the headphones interfere with timely reactions due to dull hearing.
increases the likelihood of losing or damaging your smartphone while traveling.

So, in order to protect yourself physically and financially, when listening to music (other audio files) through headphones, you should be vigilant and control the situation, especially when it comes to the street. In addition, to preserve hearing and health, you should limit the time such stress on the body and choose a high-quality headset. What to do if extraneous noise appears in your devices while listening to audio content from a computer was described step by step and in detail above.

Connecting any device to a computer is a process that requires special attention. The more complex the peripheral component, the more complex the procedure. Quite often, headphones/speakers and microphones are connected to computers. These elements help you communicate online. It is very difficult to imagine a modern user without them.

On the one hand, connecting headphones and a microphone does not require anything special. Only after the idea has been brought to life, it often takes a long time to configure these components. They work with errors. Most often, users wonder how to remove noise from headphones on a computer. Why does he even appear? What will it take to fix the problem? And is it really possible to get rid of it? If you can answer everything questions asked, connecting a headset and working with sound on a PC will not cause any trouble.

Why is there noise?

Initially, it is important to understand where the noise in the headphones comes from. Many users face this problem. Sometimes this is a temporary phenomenon, in some cases the noise does not disappear for a long time.

In fact, the nature of the problem is varied. Noise in headphones (with or without a microphone) occurs for various reasons. It is problematic to predict which alignment will help correct the situation. For example, noise may be caused by hardware damage or misconfigurations. Next, you need to figure out how to get rid of noise on your computer.

Sound card

The first reason that can affect sound quality in operating system- this is bad. If it is damaged or outdated, noise appears in the headphones.

The sound “breaks”; various crackling, squeaking and other noises may appear in the headphones or speakers. The situation can only be corrected by replacing or repairing the sound card. Only after that the headphones will disappear.

Grounding

The following problem occurs very rarely. We are talking about the lack of grounding at the sockets to which the headset and speakers/headphones in general are connected. In this case, various types of noise may appear.

If we are talking about a laptop, most likely, connecting the computer to a grounded outlet will not fix the problem. As a rule, in laptops it is the boards on the mother card that may not be grounded. You will have to either replace them or accept the problem. In some cases, users prefer not to use a particular laptop.

USB devices

Are there noises in your headphones on your computer? Usually, different kinds of sounds occur when connecting various devices. They appear immediately, not after some time.

For example, when connecting a mouse, you may hear a monotonous sound. And if we are talking about a keyboard, most likely you will hear clicks when you press the keys.

This happens due to:

Active transfer of information to the computer. Then it is recommended not to connect USB devices to certain ports. It is advisable to find other places. Or even start using a wireless headset and other devices.
Damage to the USB port. It is proposed to carry out repairs. In practice, users simply reconnect all devices to different ports.

Fortunately, this situation does not occur very often. Modern computers and laptops are made so that users can work on machines comfortably. Therefore, such a situation is unlikely to occur in practice.

Cable

How to remove noise from headphones on a computer? Much depends on what type of headset the user has. The thing is that now all devices are divided into wired and wireless. This feature plays an important role.

Often noise in speakers or headphones is found on models connected via cable. This is where the main problem lies. For example, when the cable from a microphone or headphones is damaged, various types of noise arise. This happens due to poor quality transmission of information to the sound card.

It is likely that the cable is damaged. Then the breakdown must be repaired. If wireless ones are used, this arrangement will not help.

Another trick that is advised to users with a wired headset is to remove the cord from the socket and reinsert it into the computer. This is the method that often helps get rid of noise.

Drivers

But the next source of the problem is relevant for all devices. But in practice it is rare. The thing is that strong noise in the headphones on the computer is a consequence of damage or lack of sound card or device driver.

In such a case, you simply need to reinstall or update the corresponding software package for normal operation of the operating system with the connected device. U wireless headphones As a rule, the corresponding drivers are included in the kit on a separate disk. IN as a last resort, you can download them from the website of the sound card or headset manufacturer.

Maximum sound - problems guaranteed

Background noise in headphones of any model is often encountered when the sound settings are incorrectly set. It doesn't matter whether a microphone is connected to the PC or not. After all, in this situation, nothing depends on him.

If your audio settings are set to maximum, you may experience noise or wheezing on your computer. Users who bought cheap speakers or headsets suffer from a similar problem.

The fix is simple - by turning down the sound. For example, through a mixer in the operating system. You just need to click on the gramophone image (near the clock and date), then move the slider down. So that the noise disappears. Nothing difficult or special. This is why it is recommended to buy mid-priced headphones. They encounter this problem less often.

Microphone - benefit or harm

Now it’s clear how to remove noise from headphones on a computer. But these are not all the techniques that can help. What to do if all the previously listed scenarios did not work?

The presence of a microphone on a PC plays an important role. It is this that often becomes the source of noise in headphones. What to do?

It's clearly not worth giving up the microphone. Instead, you will have to make small adjustments to the sensitivity and volume of the device. Then you will be able to get rid of excess noise.

How to do this? You need to follow a few instructions. It looks something like this:

Boot your computer. Be sure to connect a headset with a microphone.
Right-click on the mixer on the right side of the screen. In the menu that appears, click on “Sound recording devices...”.
Find the connected microphone. Double click on the corresponding line.
Go to the "Levels" tab.
Adjust the microphone volume and sensitivity by moving the sliders. If there is PC Beep, turn it off (move the volume mark to zero).
In the "Improvements" section, check the box next to "Reduce noise level". You can also check the "Remove constant component" item.

All this will help to quickly get rid of noise in the headset. How to set the microphone settings correctly? This is an individual component; each user independently selects the option that suits him.

Conclusions and Conclusions

It doesn't matter which headset is connected to the computer - wired or not. The main thing is that the majority of problems occur on all device models. for a computer with a microphone are most often connected and used without much difficulty. And the main cause of noise in the headset is the high sensitivity of the microphone, as well as the really loud environment around the user.

How to remove noise from headphones? All of the above methods will definitely help correct the situation. If we are talking about a wireless headset, then if there is constant noise, it is recommended to change the USB socket used as a receiver. Otherwise, all the previously listed tips remain the same.

Extraneous noise in headphones occasionally occurs due to virus infection. After curing the computer, the headset begins to work properly. Fortunately, these types of events are not that common. And the main methods of dealing with the problem under study are to reinstall the driver, reduce and adjust the microphone. From now on, it’s clear how to remove noise from headphones on a computer.

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 body personal computer. 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, ours USB ports give strong interference, which is amplified by the resulting earth 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 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’s a bit thick, from twisted pair cables it’s thin and brittle. No, hunting for something more civil. After rummaging through the bins, I found this work, probably from Soviet times. The next generation will no longer understand where he came from. I barely caught it myself

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

Rejoicing at the completion of the work, I assemble the entire case and turn on the computer. Hooray! No more noise in the headphones! True, there is no sound either... I collected it, of course. But he did everything carefully, it seemed like there was nowhere to make a mistake! After digging through the driver settings, I found out that not everything is so bad. The panel works, but it does not detect that a device is connected to it. If you disable the detection function, the sound goes through the headphones. Internet again? We are looking! It turns out that my panel was not HD Audio, but simply AC 97. After reading the information, I learned that this is exactly what makes them different. The ability to determine that a device has been connected. Bad. 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.

In order to begin eliminating the noise that has arisen in the headphones, you need to understand and find the cause of its occurrence. The reason may be in the headset itself, the amplification path, or the signal source.

Connection with a mobile gadget

If the headphones start to hiss when connected to an MP3 or smartphone, then the reason may be an insufficient level of reception of the frequency-modulated signal. Especially when it comes to hissing while listening to FM radio. In this case, it is necessary to unroll the cable to its entire length, and if this is not possible, then purchase a longer cable.

Try increasing the gain and decreasing the signal level. Did it help? This means the problem lay in the amplification path, it was simply overloaded.

Hissing also occurs when the signal level increases to the maximum possible. The defect can be eliminated by lowering the volume level and increasing the signal itself.

If the noise in the earphone resembles ringing, then the membrane has begun to beat against the body of the accessory. To fix this, simply lower the volume.

PC connection

The hissing sound can even be caused by outdated sound card installed on the computer. Over time, electromagnetic interference appears in it, which provokes unpleasant noise in an analog device.

An equally common problem is the lack of grounding of the outlet. If the headphones are connected to the laptop, then there is no grounding of the system board.

Hissing also occurs when headphones and any other device are connected at the same time. USB devices A. The transmission of information negatively affects sound quality.

What to do?

If hissing occurs when connecting to a PC, then connecting the ground will help correct the situation. In cases with laptops, this method is not suitable.

A solution may be to use a digital output. This will definitely prevent all noise, but for this you must be the owner of speakers with a digital-to-analog converter. Their use is also limited by the lack of a headphone jack in some systems.
