一般的音響是沒(méi)有能力讓建筑結(jié)構(gòu)完全按照自己的意圖設(shè)計(jì)的，但是對(duì)于工程質(zhì)量要求嚴(yán)格、建筑工程屬于改建結(jié)構(gòu)上進(jìn)行處理的部分情況，音響設(shè)計(jì)人員都有必要盡量提出相應(yīng)的要求。下面來(lái)講講建筑結(jié)構(gòu)中音響工程實(shí)現(xiàn)一個(gè)均勻的聲場(chǎng)的相關(guān)內(nèi)容吧。

The general sound system is not able to make the building structure design completely according to its own intention. However, it is necessary for the sound designers to put forward corresponding requirements as far as possible in the case that the project quality requirements are strict and the construction project is part of the reconstruction structure. Let's talk about the related contents of the sound engineering in the building structure to achieve a uniform sound field.

對(duì)聲均勻度的概念，一般都不是十分清楚，工程中也沒(méi)有過(guò)多的考慮，是不是就不重要了呢?不是，非常重要。舉個(gè)簡(jiǎn)單的例子：你遇然去一個(gè)娛樂(lè)廳，發(fā)現(xiàn)現(xiàn)場(chǎng)各處聲音情況不同，有的地方音樂(lè)很動(dòng)聽，有的地方又好象缺點(diǎn)什么似的，聲音飄忽不定。這就是均勻度不好造成的影響。

Generally, the concept of sound uniformity is not very clear, and there is not too much consideration in the project. Is it not important? No, very important. Take a simple example: when you go to an entertainment hall, you find that the sound conditions are different everywhere. Some places have beautiful music, and some places seem to have some shortcomings. The sound is erratic. This is the effect of poor uniformity.

在有關(guān)標(biāo)準(zhǔn)中，一般要求各點(diǎn)場(chǎng)壓級(jí)測(cè)試值偏差是小于2dB。

In relevant national standards, it is generally required that the deviation of field pressure level test value at each point is less than 2dB.

建筑結(jié)構(gòu)中應(yīng)該沒(méi)有明顯的缺陷。例如：房間中不能有太多的立柱，墻壁應(yīng)避免有圈套的弧形，尤其是舞臺(tái)一側(cè)的墻面不能有較大形結(jié)構(gòu);不能在擴(kuò)聲范圍內(nèi)出現(xiàn)較大的聲陰影區(qū)等，但是由于在建筑結(jié)構(gòu)施工后期裝飾完工后無(wú)法進(jìn)行大量的改動(dòng)來(lái)滿足這些要求，所以在音響工程中應(yīng)該盡量利用經(jīng)驗(yàn)，巧妙地安排擴(kuò)聲區(qū)，避開較大的缺陷結(jié)構(gòu)，將它們帶來(lái)的影響降到很低;

There should be no obvious defects in the building structure. For example, there should not be too many columns in the room, and the wall should avoid the arc of traps, especially the wall on one side of the stage should not have a large shape structure; It is not allowed to have large sound shadow areas within the sound reinforcement range. However, since a large number of changes cannot be made to meet these requirements after the decoration is completed in the later stage of the construction of the building structure, experience should be used as much as possible in the sound engineering to skillfully arrange the sound reinforcement areas, avoid large defective structures, and reduce their impact to a very low level;

可以及時(shí)有效地向裝飾單位提供一些簡(jiǎn)單的提高聲擴(kuò)散效果的方案。例如：所有的音樂(lè)廳都有很好的聲擴(kuò)散效果，原因是其內(nèi)部采用了大量各種形狀的聲擴(kuò)散體，而且這些結(jié)構(gòu)可以通過(guò)一些簡(jiǎn)單的裝飾方法來(lái)完成。

It can timely and effectively provide some simple schemes to the decoration units to improve the sound diffusion effect. For example, all concert halls have good sound diffusion effect, because a large number of sound diffusers of various shapes are used inside, and these structures can be completed by some simple decoration methods.

所以只要方法得當(dāng)應(yīng)該可以達(dá)到較好的效果，當(dāng)然要想對(duì)擴(kuò)散體的形狀，位置、數(shù)量進(jìn)行合理恰當(dāng)?shù)脑O(shè)計(jì)不是件容易的事，一般比較經(jīng)濟(jì)可行的辦法就是采用墻體水泥拉毛的方法，雖然這種方法顯得比較陳舊而且不太美觀，但它對(duì)廳堂的聲擴(kuò)散能起到非常有效的作用。

Therefore, as long as the method is appropriate, it should be able to achieve better results. Of course, it is not easy to design the shape, position and quantity of the diffuser reasonably and properly. Generally, the more economical and feasible method is to use the wall cement roughening method. Although this method seems old and not beautiful, it can play a very effective role in the sound diffusion of the hall.

山東音響廠家認(rèn)為合理地布置音響系統(tǒng)，尤其是音箱的擺位一定要嚴(yán)格要求。假如在設(shè)計(jì)中能采用某些音箱廠商提供的電腦設(shè)計(jì)軟件進(jìn)行聲場(chǎng)模擬就再好不過(guò)了，如果沒(méi)有，就應(yīng)該在實(shí)際調(diào)整，直到現(xiàn)場(chǎng)聲場(chǎng)很佳為止。

Shandong audio manufacturers believe that the reasonable layout of the audio system, especially the placement of the speakers, must be strictly required. If the computer design software provided by some speaker manufacturers can be used for sound field simulation in the design, it would be better. If not, it should be adjusted in practice until the sound field is very good.
