Why are the speakers humming?

It often happens that only after buying new speakers or working with old and already tested ones, we begin to notice that something wrong is happening with them. The sound has deteriorated. They themselves hum and extraneous sounds are emitted from them. Let's try to figure it out.

Why did the sound transmission deteriorate?

The first thing you should pay attention to if you notice that the sound of the speakers has deteriorated and extraneous noise is coming from them is the integrity of the cable. Check its entire length for damage, for example:

• kinks;
• breaks in the braid;
• are there any internal wire fractures?
• it was not chewed by pets;

If the cable is detachable, connect it to another device and check there.

Damage to connectors. Sooner or later, with active use of the device, its connectors wear out. This is noticeable, for example, by the play of the plug, but it should fit tightly. Try pulling out the plug, then reinserting it, twisting it in the socket. Noise will immediately be heard from the speakers.

REFERENCE! If it is not possible to purchase new speakers, then you can simply fix the cable in its normal state, in which it does not cause interference.

Very long cable. Often the sound is distorted due to the fact that there are a large number of kinks in the cable, especially if it is very long and the distance to the computer is not particularly large. In such a case, try to maintain the cable installation that was made at the factory.

Operation of faulty connectors. As a rule, any system unit has two inputs for connecting audio systems. One is located on the front panel of the case, and the second is on the motherboard. The front connector very quickly becomes unusable and begins to work poorly, or even does not detect the device at all.

Binding. Many computer owners like to intertwine wires with each other so that they do not stick out in different directions. But this entails cable kinks, and as a result, humming.

Speakers hum when you pick up your phone

Speakers often make noise and produce interference when your mobile device receives an SMS or suddenly starts ringing. Actually, any equipment that has an antenna leads to similar effects in the speakers. But sometimes printers and even table lamps can cause them. Try to move potential sources of interference away from your computer one at a time and this way you can find the culprit.

Constant humming from your speakers when they're turned on is mostly normal. Not that it should be so, but it is simply related to the circuit design of the sound card and the speakers themselves. This happens due to the fact that if the sound card does not receive power, then it begins to pick up any interference from everything around it. To get rid of this, you need to ground the computer case and reduce the input impedance of the speakers to about 20 kOhm.

How to get rid of harmful sound

Before getting rid of noise, it is necessary to find out the cause of its occurrence. It is quite possible that the amplifier or cable is poorly shielded. This is very easy to check; just hold the cable with your hand. If the noise intensifies, you just need to wrap the cable with foil, or better yet, buy a shielded one.

If the noise is caused by the amplifier, then you will have to open the speakers and shield them. Perhaps the computer is not grounded and the voltage that is present on its case passes through the body of the audio system and causes interference. If the computer is grounded, the noise may disappear.

REFERENCE! You can check the mixing settings of the speakers. Find the Sound item in the Control Panel. Going to the “Playback” tab, find the speaker indicator and in the properties, on the “Levels” tab, you will need to turn off the line input.

If none of the above helps, then there can only be one way out - replacing the speakers with new ones.

And, most importantly, do not confuse noise with background. Absolutely any speakers sound bad. The only difference is that expensive speakers begin to hum when the volume level is almost at the maximum level. Budget Chinese speakers begin to produce noise when the volume does not even reach half of what is possible, and often even less. Thus, we will not identify the background with noise.
