山東公共廣播音響具有很強(qiáng)的現(xiàn)場(chǎng)性，擴(kuò)聲設(shè)備一般要求在演出現(xiàn)場(chǎng)實(shí)時(shí)調(diào)節(jié)，不允許在調(diào)音時(shí)出現(xiàn)一點(diǎn)聲音分割的誤差，否則，可能會(huì)造成很不好的后果，所以無(wú)論是在音響系統(tǒng)的設(shè)計(jì)還是現(xiàn)場(chǎng)調(diào)音都要保證演出的正常進(jìn)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.
在擴(kuò)聲系統(tǒng)中包括放音拾音到出音的整個(gè)過(guò)程，在很大程度上，聲音的聲音很容易被麥克風(fēng)的聲反饋噪聲所引起，而在其他系統(tǒng)中，由于電話的發(fā)聲區(qū)、聲場(chǎng)和音頻放音區(qū)、擴(kuò)聲區(qū)不在同一個(gè)空間，所以音頻的聲音不能通過(guò)空間傳到麥克風(fēng)，也就不會(huì)有聲反饋噪聲。
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，從事擴(kuò)聲工作的音響師須掌握聲反饋的方法；保證設(shè)備，擴(kuò)聲系統(tǒng)聲音變化大，事故多。調(diào)音時(shí)，稍有疏忽就可能導(dǎo)致功放或聲音燒毀，造成不要的損失。在系統(tǒng)設(shè)計(jì)和調(diào)試中，要注意采取各種措施，盡量減少設(shè)備燒毀的發(fā)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.
現(xiàn)代聲場(chǎng)設(shè)計(jì)要求充分利用來(lái)自擴(kuò)聲系統(tǒng)的直達(dá)聲，合理控制反射聲，聲音懸掛是獲得直達(dá)聲的佳方式，聽(tīng)音區(qū)可以看到所有聲音的整體；
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;
聽(tīng)音區(qū)在所有聲音交叉輻射的區(qū)域內(nèi)，混響聲到達(dá)早期反射后，聲音發(fā)生了多次反射，房間界面合適的混響聲可以使聲音環(huán)境變好，有助于提高聲音的豐滿度，強(qiáng)烈的混響聲會(huì)破壞聲音的清晰度，聲音的混響和直達(dá)聲的比例，決定了聽(tīng)聲源的距離，當(dāng)混響比大時(shí)，聲源離得遠(yuǎn)，而當(dāng)混響比小時(shí)，聲源離得近。
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.
在音響系統(tǒng)中可以通過(guò)調(diào)節(jié)無(wú)聲音聲音和處理立體聲聲音的比例關(guān)系，控制距離，如音響設(shè)置混響強(qiáng)度調(diào)節(jié)旋鈕，左為干，即直達(dá)聲，右為濕，聲音效果，此按鈕可以調(diào)節(jié)混響聲音的音量，早期反射也稱為近時(shí)間反射，它是直達(dá)聲后50毫秒內(nèi)到達(dá)的聲音，通過(guò)一次或兩次反射到達(dá)聽(tīng)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.
