山东公共广播音响具有很强的现场性，扩声设备一般要求在演出现场实时调节，不允许在调音时出现一点声音分割的误差，否则，可能会造成很不好的后果，所以无论是在音响系统的设计还是现场调音都要保证演出的正常进行。
Shandong public broadcasting audio has a strong on-site nature. The sound reinforcement equipment generally requires real-time adjustment at the performance site, and it is not allowed to have a little error in sound segmentation during tuning, otherwise, it may cause very bad consequences. Therefore, it is necessary to ensure the normal performance in the design of the audio system and on-site tuning.
在扩声系统中包括放音拾音到出音的整个过程，在很大程度上，声音的声音很容易被麦克风的声反馈噪声所引起，而在其他系统中，由于电话的发声区、声场和音频放音区、扩声区不在同一个空间，所以音频的声音不能通过空间传到麦克风，也就不会有声反馈噪声。
In the sound reinforcement system, the whole process from sound reproduction and sound collection to sound output is included. To a large extent, the sound of the sound is easily caused by the acoustic feedback noise of the microphone. In other systems, because the sound producing area and sound field of the telephone are not in the same space as the audio reproduction area and sound reinforcement area, the audio sound cannot be transmitted to the microphone through the space, so there will be no acoustic feedback noise.
所以，从事扩声工作的音响师须掌握声反馈的方法；保证设备，扩声系统声音变化大，事故多。调音时，稍有疏忽就可能导致功放或声音烧毁，造成不要的损失。在系统设计和调试中，要注意采取各种措施，尽量减少设备烧毁的发生。
Therefore, sound engineers engaged in sound reinforcement must master the method of eliminating sound feedback; To ensure the safety of the equipment, the sound of the sound reinforcement system changes greatly and there are many accidents. When tuning, a little negligence may cause the power amplifier or sound to burn, causing unnecessary losses. During system design and commissioning, various measures shall be taken to minimize equipment burning.
现代声场设计要求充分利用来自扩声系统的直达声，合理控制反射声，声音悬挂是获得直达声的佳方式，听音区可以看到所有声音的整体；
Modern sound field design requires full use of direct sound from professional sound reinforcement system, reasonable control of reflected sound, sound suspension is a good way to obtain direct sound, and the whole of all sounds can be seen in the listening area;
听音区在所有声音交叉辐射的区域内，混响声到达早期反射后，声音发生了多次反射，房间界面合适的混响声可以使声音环境变好，有助于提高声音的丰满度，强烈的混响声会破坏声音的清晰度，声音的混响和直达声的比例，决定了听声源的距离，当混响比大时，声源离得远，而当混响比小时，声源离得近。
The listening area is in the area where all sounds cross radiate. After the reverberation reaches the early reflection, the sound is reflected many times. A suitable reverberation at the room interface can improve the sound environment and help improve the fullness of the sound. Strong reverberation will destroy the clarity of the sound. The proportion of reverberation and direct sound determines the distance from the listening source. When the reverberation ratio is large, the sound source is far away, and when the reverberation ratio is small, The sound source is close.
在音响系统中可以通过调节无声音声音和处理立体声声音的比例关系，控制距离，如音响设置混响强度调节旋钮，左为干，即直达声，右为湿，声音效果，此按钮可以调节混响声音的音量，早期反射也称为近时间反射，它是直达声后50毫秒内到达的声音，通过一次或两次反射到达听者。
In the audio system, the distance can be controlled by adjusting the proportion between no sound sound and stereo sound. For example, the audio setting reverberation intensity adjustment knob, left is dry, that is, direct sound, right is wet, and the sound effect. This button can adjust the volume of reverberation sound. Early reflection is also called near-time reflection. It is the sound that arrives within 50 milliseconds after direct sound and reaches the listener through one or two reflections.
