音響的噪聲問題經常困擾我們，其實只要認真分析和排查，絕大多數的音響噪聲都是可以自行解決的。那么這里簡單的分析一下音響產生其他方面噪聲的原因，以及自行排查方法。
The problem of sound noise often puzzles us. In fact, as long as we carefully analyze and troubleshoot, the vast majority of sound noise can be solved by ourselves. Here is a brief analysis of the causes of noise in other aspects of the audio system and the self troubleshooting methods.
1、插卡不正
1. Incorrect card insertion
由聲卡沒有同主板擴展槽嚴密分離造成，很常見，只要將聲卡插正就解決了。
This is caused by the fact that the sound card is not closely separated from the expansion slot of the motherboard. It is very common. Just insert the sound card correctly.
2、線路輸入不實
2. Incorrect line input
有源音箱，無論是2.0聲道的還是2.1聲道的都有從音源到音箱的線路輸入信號線，如果這根線接入不實，就可能造成雜音。另外，有些聲卡只有一個輸出端，需要調整跳線。
Active speakers, whether 2.0 channel or 2.1 channel, have a line input signal line from the sound source to the speaker. If this line is not connected properly, it may cause noise. In addition, some sound cards have only one output terminal, and the jumper needs to be adjusted.
3、聲卡驅動問題
3. Sound card driving problem
系統自帶的聲卡驅動程序可能不兼容或者驅動出現問題了。如果這樣，可以重裝或者換一個聲卡驅動程序。
The sound card driver of the system may be incompatible or the driver may have problems. If so, you can reinstall or replace the sound card driver.
4、音視頻文件質量問題
4. Audio and video file quality problems
如果網絡上下載的音視頻文件質量差，就會造成播放時有雜音產生，盡可能下載質量好的音視頻文件。
If the quality of audio and video files downloaded from the network is poor, it will cause noise during playback. Try to download high-quality audio and video files.
5、音箱損壞
5. Speaker damaged
無論什么音箱，時間長了都會老化損壞，損壞的音箱繼續使用就會有雜音出現。如果雜音真的是這個原因造成的，送修或換新吧。
No matter what speakers are, they will be aged and damaged over a long period of time. If the damaged speakers continue to be used, there will be noise. If the noise is really caused by this reason, send it for repair or replacement.
常用的排查方法和解決方式：
Common troubleshooting methods and solutions:
將電腦音頻交換著接入低音炮的左右聲道（紅、白蓮花插頭），聽音箱有沒有噪音。
Switch the computer audio into the left and right channels of the subwoofer (red and white lotus plugs) and listen for any noise from the speaker.
A、如果一只報告廳音音箱沒有噪音而另一只有，說明音頻線壞了，需要更換音頻線
A. If one speaker reports that there is no noise in the hall sound box and the other only reports that the audio cable is broken and needs to be replaced
B、如果都有噪音，說明問題不在音頻線上
B. If there is noise, the problem is not on the audio line
把低音炮連接兩個小音箱的連接線互換一下，聽音箱有沒有噪音。
Swap the connecting wires between the subwoofer and the two small speakers, and listen for any noise.
A、如果一只音箱沒有噪音而另一只有，說明音箱內部電路或者路線出問題了，可以找人打開低音炮檢查診斷具體情況并解決。
A. If one speaker has no noise while the other has only, there is a problem with the internal circuit or route of the speaker. You can find someone to turn on the subwoofer to check, diagnose and solve the specific situation.
B、如果依然有噪聲，說明機箱連接線有問題，或者這個小機箱有問題。
B. If there is still noise, there is a problem with the chassis cable, or there is a problem with the small chassis.
用耳機聽。
Listen with headphones.
如果耳機有一只有噪音說明電腦聲卡硬件或軟件存在問題。如果耳機沒有噪音，那么就可以確定是電腦外部擴聲設備的問題，即從音頻連接線開始，到2個小音箱之間的部分存在問題。
If there is only noise in the headset, there is a problem with the computer sound card hardware or software. If there is no noise in the headphones, it can be determined that there is a problem with the external sound reinforcement equipment of the computer, that is, there is a problem from the audio cable to the part between the two small speakers.
講了這么多，要從根本上減少音響噪音，還得從以下方面著手：
After all, to fundamentally reduce the sound noise, we have to start from the following aspects:
1、選擇用料足的大企業音響；
1. Choose big brand audio with sufficient materials;
2、盡量較少電磁干擾，合理排線，遠離手機、無線電接受器、發射器等輻射干擾設備；
2. Try to minimize electromagnetic interference, arrange cables reasonably, and keep away from mobile phones, radio receivers, transmitters and other radiation interference equipment;
3、信號線接實
3. Signal line connection
4. Keep the audio equipment in the lecture hall clean to reduce dust and wear.
