First, electromagnetic radiation
Electromagnetic radiation produces such noise. Everyone knows that there are noises for everyday mobile phones, walkie-talkies and other communication devices, so it is recommended that you do not place electronic devices (such as mobile phones) close to audio devices when using audio equipment.
Second, power interference
The interference noise of the power supply, when noise occurs in the audio equipment, is generally when we do not meet the standard in the entire acoustic engineering design. If you want to avoid this situation, it is better to design the lighting lines of the private room separately when designing lighting and sound projects.
Third, the inside of the device
The noise generated inside the audio equipment, if the quality of the purchased audio equipment is too poor, there will be noise problems. Therefore, when purchasing or renting an audio, you must check the audio equipment.
