To create a festive atmosphere of festive events is impossible without high-quality musical design. The presence of an unpleasant sound or whistle emitted by the speakers introduces a dissonance. When you have to face a similar problem in a home environment, negative emotions force you to turn off the speakers that are buzzing, and to deal with the causes of such noise.
Why speakers can sound
If there are unpleasant sound vibrations on the audio system, computer or in the car, first, find out the reasons. We list the main ones:
- poor contact of the wires connecting the speakers to the sound source;
- poor cable shielding or lack thereof;
- lack of grounding of radio equipment;
- lack of screen on the amplifier;
- unsuccessful arrangement of speakers in relation to the source;
- Incorrect connection (mixing) settings
- malfunction of the board or one of its elements;
- failure in the equalizer or amplifier settings;
- moving the microphone.
The listed problems directly affect the quality of the sound produced. Some of them can cause noise constantly, while others - periodically. Correction of the defect can be performed after identifying the cause. Diagnosis of each of them is time-consuming and requires attention.
ATTENTION! Most speakers that convert the audio signal are equipped with a special screen that protects the signal from an external magnetic field. Stationary broadband speakers are not adequately protected and are subject to the effects of electrical vibrations from other sources.
What to do if the speakers are lit
To eliminate unpleasant noise, it is necessary to identify the cause of the occurrence and take the necessary measures to eliminate it.
Software Background Elimination Techniques
If the problem is related to the settings of acoustic or computer equipment, then it is advisable to first study the technical parameters of the speakers and the signal source, as well as the instructions. Diagnosis of such a malfunction is done by connecting speakers to another computer or amplifier. If the speakers cease to fade when connected to another sound source, you need to adjust the settings.
Perform this as follows:
- include a system unit;
- after that, in the start menu find the "Control Panel" section;
- further, they move along the opening windows: “Sound” and “Play”;
- in the latter, find the “Properties” section and the subsection with the name “Levels”, in which the Line Input function is adjusted;
- after the changes, turn on the speakers and check the sound quality.
IMPORTANT! If the section "Playback" does not reflect the connection of the speakers, then the problem is related to the drivers or the lack of contacts on the connectors. When the reason is related to the settings, the drivers are updated to fix this problem. They find a bad contact, and connect the wires.
When performing audio software adjustments, carefully study the technical parameters of the speakers. After that, they enter data into the equalizer or amplifier settings and turn on the speakers.
Other methods
The appearance of excess noise when the speakers are turned on is diagnosed by touching the connection wires. If the sound vibrations change, then the speakers are affected by electromagnetic waves. To eliminate this problem, use a foil in which they wrap the cable or change the connection wire to a special - shielded one.
REFERENCE! Using a stationary cable with a protective screen will allow you to get rid of the effects of magnetic fields and the appearance of excess noise when connecting speakers.
If the speakers are not shielded, then the foil is fixed inside the speaker casing, leaving only the plane for sound output free. Such measures must be taken, because a magnetic field occurs not only in the connection wires, but also in other electrical networks.
Failure of the component parts of the board can cause unpleasant noise. To identify such a disadvantage, carefully examine the internal elements of the amplifier. Finding burnt, swollen capacitors or resistors in the circuit, they are replaced with new ones. Also check the fit of all contacts to the board.
When the speakers are on the same level as the audio system or system unit, an unpleasant background may periodically appear or be constantly present. To eliminate such noise, computer attributes are set higher using furniture, and stationary speakers are mounted on stands.
One of the reasons may be the lack of grounding in the network. To get rid of this problem, check the network and connect the necessary contacts. Not all living spaces are equipped with a fixed ground connection. If this is the case, then you need to connect the amplifier housing with the battery with a cable and thereby get rid of the problem.
Fans of karaoke are faced with the problem of the appearance of unpleasant noise, and sometimes a whistle, when connecting a microphone. This is due to the lack of shielded protection on it in whole or in part, which can occur when the microphone is turned in the direction of the speakers.
When you turn on various household electrical appliances: fan, vacuum cleaner, electric oven, etc., noise may appear in the speakers. This is due to the low level of protection of the audio equipment from magnetic oscillations.
Sound quality largely depends on the correct settings and the availability of shielded radio protection. So that the speakers do not fonil use audio equipment of well-known brands that you can trust.
