A brief analysis of the four reasons why audio equipment produces noise

In daily life or when singing in a KTV room, I believe everyone has encountered the problem of audio noise. The "squeaky" noise makes people feel very uncomfortable. So, we can't help but ask, why does the audio equipment make noise? Here we will introduce to you the four reasons why the audio equipment makes noise during audio failure.

1. Noise caused by electromagnetic radiation

Electromagnetic radiation causes interference from stray electromagnetic waves in the noisy environment, such as high-frequency electromagnetic waves from mobile phones, walkie-talkies and other communication equipment. In order to allow guests to sing comfortably, the solution to this noise is to require our employees to gently remind guests not to bring their communication equipment close to our audio equipment when providing services to guests.

2. Noise generated by ground loop

In the sound system, the whole system must be well grounded, and the grounding resistance is required to be less than 4 ohms. Otherwise, the induced charges generated by various radiation and electromagnetic induction in the lighting and sound rental system will not be able to flow into the ground, thus forming a noise voltage superimposed on the audio signal.

3. Noise generated by power supply interference

When our audio equipment has problems, it is usually because we did not meet the standards when designing the entire audio project. If we want to avoid this phenomenon, we should try to separate the power lines in our private rooms when designing the lighting and audio rental project.

4. Noise generated inside the audio equipment

If the quality of the audio equipment we buy in KTV is not good, there are also reasons for this. Therefore, when we purchase lighting and audio rental equipment, we need to pay attention to the fact that audio equipment has an indicator - signal-to-noise ratio. Everyone needs to pay attention to this information when purchasing.
