It often happens that only by buying new speakers or working with old and already tested speakers, we begin to notice that something is wrong with them. The sound has deteriorated. They themselves are buzzing and extraneous sounds are made from them. We’ll try to figure it out.
Why did the sound transmission fail?
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, so this is the integrity of the cable. Check it all the way for damage on it, for example:
- excesses;
- braid breaks;
- are there any internal fractures of the wire;
- his pets did not chew;
If the cable is removable, connect it to another device and check there.
Damage to connectors.Sooner or later, but with the active use of the device, its connectors wear out. This is noticeable, for example, by the play of the plug, and it should sit tight. Try to pull out the plug, then reinsert, twist in the socket. Noise will immediately be heard from the speakers.
REFERENCE! If there is no opportunity to purchase new speakers, then you can simply fix the cable in a normal state in which it does not cause interference.
Very long cable.Often the sound is distorted due to the fact that the cable has a large number of bends, especially if it is very long, and the distance to the computer is not very large. In this case, try to keep the cable laying that was done at the factory.
Operation of faulty connectors.As a rule, in any system unit there are two inputs for connecting audio systems. One is located on the front of the case, and the second on the motherboard. The front connector very quickly becomes unusable and starts to work poorly, or even does not determine the device at all.
BindingMany computer owners like to twist wires with each other so that they do not stick out in different directions. But this entails cable creases, and as a result, a buzz.
The speakers buzz when you bring the phone
Speakers often make noise and interfere when a mobile device receives SMS or suddenly it starts ringing. Actually, any technique that has an antenna leads to the appearance of similar effects in the speakers. But sometimes printers and even table lamps can call them. Try to remove potential sources of interference from the computer one at a time, and thus, you can find the culprit.
The constant humming of the speakers when they are turned on is, for the most part, normal. Not that it should be so, but it is simply connected with the circuitry of the sound card and the speakers themselves. This happens due to the fact that if power is not supplied to the sound card, it starts to catch any interference from everything around. To get rid of this, it is necessary to ground the computer case, 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 possible this is a poorly shielded amplifier or cable. It is very easy to check it, just take the cable with your hand. If the noise is amplified, you just need to wind the cable with foil, and it is better to purchase a shielded one.
If the reason for the noise is the amplifier, then you 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 case of the audio system and causes interference. If you ground the computer, noise may disappear.
REFERENCE! You can check the mix settings of the speakers. Find the “Sound” item in the “Control Panel”. Going to the “Playback” tab, look for the column 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, the noise should not be confused with the background. Fonite absolutely any speakers. The only difference is that expensive speakers begin to fade when the volume level is almost at the maximum mark. Budget Chinese speakers are already starting to fade when the volume does not reach even half of what is possible, and often even less. Thus, we will not identify the background with noise.
