音响的噪声问题经常困扰我们，其实只要认真分析和排查，绝大多数的音响噪声都是可以自行解决的。那么这里简单的分析一下音响产生其他方面噪声的原因，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
由声卡没有同主板扩展槽严密分离造成，很常见，只要将声卡插正就解决了。
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、线路输入不实
2. Incorrect line input
有源音箱，无论是2.0声道的还是2.1声道的都有从音源到音箱的线路输入信号线，如果这根线接入不实，就可能造成杂音。另外，有些声卡只有一个输出端，需要调整跳线。
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、声卡驱动问题
3. Sound card driving problem
系统自带的声卡驱动程序可能不兼容或者驱动出现问题了。如果这样，可以重装或者换一个声卡驱动程序。
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、音视频文件质量问题
4. Audio and video file quality problems
如果网络上下载的音视频文件质量差，就会造成播放时有杂音产生，尽可能下载质量好的音视频文件。
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、音箱损坏
5. Speaker damaged
无论什么音箱，时间长了都会老化损坏，损坏的音箱继续使用就会有杂音出现。如果杂音真的是这个原因造成的，送修或换新吧。
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决方式：
Common troubleshooting methods and solutions:
将电脑音频交换着接入低音炮的左右声道（红、白莲花插头），听音箱有没有噪音。
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.
础、如果一只报告厅音音箱没有噪音而另一只有，说明音频线坏了，需要更换音频线
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
叠、如果都有噪音，说明问题不在音频线上
B. If there is noise, the problem is not on the audio line
把低音炮连接两个小音箱的连接线互换一下，听音箱有没有噪音。
Swap the connecting wires between the subwoofer and the two small speakers, and listen for any noise.
础、如果一只音箱没有噪音而另一只有，说明音箱内部电路或者路线出问题了，可以找人打开低音炮检查诊断具体情况并解决。
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.
叠、如果依然有噪声，说明机箱连接线有问题，或者这个小机箱有问题。
B. If there is still noise, there is a problem with the chassis cable, or there is a problem with the small chassis.
用耳机听。
Listen with headphones.
如果耳机有一只有噪音说明电脑声卡硬件或软件存在问题。如果耳机没有噪音，那么就可以确定是电脑外部扩声设备的问题，即从音频连接线开始，到2个小音箱之间的部分存在问题。
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.
讲了这么多，要从根本上减少音响噪音，还得从以下方面着手：
After all, to fundamentally reduce the sound noise, we have to start from the following aspects:
1、选择用料足的大公司音响；
1. Choose big brand audio with sufficient materials;
2、尽量较少电磁干扰，合理排线，远离手机、无线电接受器、发射器等辐射干扰设备；
2. Try to minimize electromagnetic interference, arrange cables reasonably, and keep away from mobile phones, radio receivers, transmitters and other radiation interference equipment;
3、信号线接实
3. Signal line connection
4. Keep the audio equipment in the lecture hall clean to reduce dust and wear.
