| Replace high-quality cables | Headphones, microphone | 4.3 |
| Isolate sources of interference | Co-playing mobile phones and audio equipment | 4.1 |
| Update drivers | Computer sound card problem | 3.9 |
3. Scenario processing guide
1. Computer current sound solution
Recent forum data shows that 60% of computer-related current sound problems can be solved through the following steps: ① Unplug all external devices for testing; ② Update the sound card driver to the latest version; ③ Disable the "Microphone Enhancement" function in the control panel.
2. Current sound when the mobile phone is charging
Popular suggestions include: replace the original charger (non-original chargers cause problems up to 73% of the time), avoid using audio applications while charging, and turn on airplane mode for testing.
3. Sound system current sound
The professional audio community recommends three steps: check whether all interfaces are oxidized (accounting for 38% of the problems), try to connect the power amplifier separately for testing, and use balanced connections instead of unbalanced connections.
4. New technology solutions for 2023
| Technical name | Principle | Applicable equipment |
|---|---|---|
| AI noise reduction chip | Identify and filter specific frequency band noise in real time | TWS headsets, conference systems |
| Photoelectric isolation transmission | Replace electrical signal transmission with optical signals | Professional recording equipment |
| Intelligent power management | Dynamically adjust power supply waveform | High-end motherboards and sound cards |
5. Effective tips tested by users
According to the hot posts on social media: ① Use aluminum foil to wrap the data cable when charging the mobile phone (reduce interference); ② Add a magnetic ring to the router (improve wireless audio quality); ③ Use an eraser to clean the device interface (oxidation treatment).
6. When does it require professional maintenance?
When the following conditions occur, it is recommended to send it for repair immediately: ① The sound of electric current accompanies the device heating (danger signal); ② All basic methods are invalid; ③ The device is within the warranty period (avoid disassembling it by yourself to affect the warranty).
Through analysis of recent network hot spots, it can be seen that although current sound problems are common, most of them can be solved through system troubleshooting. It is recommended that users try it step by step according to specific scenarios and consult professional technicians if necessary. Maintaining equipment maintenance and reasonable usage habits can effectively prevent the occurrence of most electrical noise problems.
