（三）杂音干扰 1. 电磁干扰：检查周围是否有电磁设备产生干扰，如存在，请移开干扰源。 2. 声卡设置：调整声卡设置，降低噪音门限。 3. 硬件问题：如以上方法均无效，可能是声卡硬件问题，请联系专业人员进行检修。 （四）麦克风收音效果差 1. 麦克风设置：检查麦克风设置及增益，确保麦克风处于正常工作状态。 2. 麦克风距离：调整麦克风与嘴部的距离，过近或过远都会影响收音效果。 3. 过滤背景噪音：使用语音处理软件进行背景噪音过滤。 三、英文解释

FAQ on Sound Card Issues of Computers: How to Improve Sound Quality?

Common Issues of Sound Card:

1. Distorted sound

2. No sound output 3. Noise interference 4. Poor microphone recording quality Solutions: (I) Distorted sound: Check if the sound card driver is up to date, if not, update it. Check for hardware conflicts,拔掉冲突设备或更换声卡。 If the distortion is from the source, try replacing the audio file. (II) No sound output: Check the connections of speakers, headphones and other devices to the computer. Ensure that the system volume and application volume settings are not set to mute. If the sound card driver is not installed or installed incorrectly, reinstall the driver. (III) Noise interference: Check for electromagnetic interference from surrounding devices and move them away if possible. Adjust sound card settings to lower the noise threshold. If none of these work, it may be a hardware issue with the sound card, so contact a professional for inspection and repair. (IV) Poor microphone recording quality: Check the microphone settings and gain to ensure it is working properly. Adjust the distance between the microphone and the mouth as too close or too far can affect the recording quality. Use voice processing software to filter out background noise.
