我是搞環(huán)保隔音工作的，增音設計還真沒(méi)考慮過(guò)。

我覺(jué)得，從源頭上，可以讓聲音通過(guò)四周的幾級大喇叭筒將聲音放大；

從傳播過(guò)程中，要注意演播的舞臺要設置高一點(diǎn)，不然前面的觀(guān)眾能聽(tīng)到，后面的就因前面的擋住減弱了；另外演播廳要設計成圓拱形的，美觀(guān)又便于回音；

在收聽(tīng)點(diǎn)位上，要讓觀(guān)眾席像一般的**院一樣，前排低，后排高，便于充分利用視聽(tīng)空間。

演播廳構建的時(shí)候如何利用回音原理

一、室內聲音的傳播

1. 反射與前次反射

聲波在傳播過(guò)程中，若遇到比它波長(cháng)大的物體表面，便會(huì )產(chǎn)生反射。當反射面比聲波的波長(cháng)大很多時(shí)，反射規律與幾何光學(xué)相似，即聲線(xiàn)的反射角等于入射角。這時(shí)，我們可以用幾何聲學(xué)來(lái)研究反射的情況。

我們把聽(tīng)到直達聲后50ms以?xún)鹊竭_的反射聲稱(chēng)為前次反射或早期反射。由于哈斯效應，前次反射聲人耳不但分辨不出來(lái)，而且還會(huì )將它當作直達聲的一部分，在主觀(guān)效果上增加了聲音的響度但又不會(huì )影響清晰度。這也是為什么在室內講話(huà)時(shí)要比在室外講話(huà)聽(tīng)起來(lái)聲音響一些的緣故。

劇場(chǎng)與音樂(lè )廳的前次反射強弱程度是一個(gè)很重要的聲學(xué)條件，18世紀在歐洲建造的一些古典音樂(lè )廳，以音質(zhì)效果極佳而著(zhù)稱(chēng)于世，曾使很多聲學(xué)家和建筑學(xué)家感到迷惑。但后來(lái)的研究和工程實(shí)踐表明，一些優(yōu)秀的古典音樂(lè )廳，除了良好的聲**與適度混響之外，很重要的原因是這些劇場(chǎng)或音樂(lè )廳的觀(guān)眾席有足夠的前次反射，尤其是來(lái)自側向和頂棚的前次反射聲增加了室內聲能密度，提高了音樂(lè )的空間感和豐滿(mǎn)度。

2. 混響與最佳混響時(shí)間

混響是建筑聲學(xué)中最重要的參數之一，適度的混響，可以明顯的改善聲音質(zhì)量，改變音樂(lè )的音色和風(fēng)格。

我們已經(jīng)知道，室內的聲波遇到四周墻面以及地面和頂棚會(huì )產(chǎn)生反射，而這種反射過(guò)程是往復多次的，從而延長(cháng)了到達聽(tīng)者的時(shí)間。如果這些反射聲在直達聲到達聽(tīng)者50ms后仍多次反射而繼續存在，直到一段時(shí)間后才衰減消失，聽(tīng)起來(lái)有一種余音不絕的感覺(jué)。這種過(guò)程與現象，我們稱(chēng)為混響，即交混回響之意。

那么，如何確定混響從建立到消失的時(shí)間呢？也就是說(shuō)，如何確定混響時(shí)間呢？上個(gè)世紀初，聲學(xué)家賽賓（W.C.Sabie）通過(guò)研究后提出：當聲源停止發(fā)聲后，殘余的聲能在室內往復反射，經(jīng)吸收衰減，其聲能密度下降為原來(lái)值的百萬(wàn)分之一所需要的時(shí)間，或者說(shuō)，室內聲能密度衰減60dB所需要的時(shí)間稱(chēng)為混響時(shí)間。

混響時(shí)間的實(shí)測值與計算值會(huì )有一定的差值。一般來(lái)說(shuō)，低頻混響時(shí)間的實(shí)測值小于計算值，高頻混響時(shí)間的實(shí)測值大于計算值。在實(shí)際計算時(shí)應根據經(jīng)驗作一些修正。

混響時(shí)間對聲學(xué)品質(zhì)的影響是眾所周知的，過(guò)長(cháng)過(guò)短都會(huì )使觀(guān)眾感到疲勞。只有適當的混響時(shí)間，才會(huì )使觀(guān)眾處于一種賞心悅目的藝術(shù)享受之中，此時(shí)聲音豐滿(mǎn)動(dòng)聽(tīng)，音符生動(dòng)活躍、語(yǔ)言親切溫柔，使觀(guān)眾有強烈的空間感和豐富的色彩感。

那么，多長(cháng)的混響時(shí)間才是最佳的呢？

事實(shí)上，很難確認一個(gè)統一的最佳混響時(shí)間標準，沒(méi)有一個(gè)確定的數據，很大程度上是個(gè)范圍值。不同類(lèi)型，不同風(fēng)格，不同專(zhuān)業(yè)用途的劇場(chǎng)都有不同要求。而且，它還受民族文化背景的影響。因此，各國發(fā)表的數據都不盡相同。

低頻段混響時(shí)間稍長(cháng)有利于音樂(lè )的豐滿(mǎn)度和語(yǔ)言的溫暖感，適宜于各類(lèi)音樂(lè )演出，而高頻段混響時(shí)間長(cháng)一點(diǎn)，則容易表現泛音，增加音樂(lè )“水分”與鮮活感。

不同頻率的不同混響決定了劇場(chǎng)的音色特性。在硬質(zhì)裝飾材料的環(huán)境中，高頻混響時(shí)間長(cháng)，音色冷艷，音色效果能模仿出山洞，水泥大廳，大理石宮殿等。而軟質(zhì)裝飾材料的低頻混響突出，音色偏暖，有著(zhù)古典音樂(lè )廳與歌劇院的特色。

3. 聲能比和等效混響

混響在主觀(guān)感覺(jué)上還與一個(gè)物理量有關(guān)：等效混響。

等效混響時(shí)間的存在，要求我們在舞臺擴音與錄音時(shí)要充分考慮其影響，因此，我們建議，對大型樂(lè )隊、歌劇的舞臺擴音或錄音應采用整體式遠場(chǎng)拾音，不宜采用多點(diǎn)式近場(chǎng)拾音，傳聲器的指向性不可太銳，以充分拾取到劇場(chǎng)空間自然混響聲，使音樂(lè )更趨于豐滿(mǎn)、自然。

4. 回聲

回聲與混響是有區別的。

混響在英文中是Reverberation，是指聲音經(jīng)過(guò)多次往復漫反射，包含多個(gè)不同角度、不同時(shí)間到達的混合反射聲逐漸衰減形成，聽(tīng)者分辨不出其中的任何音節。

而回聲是一種單一固定的反射聲，它的強度和時(shí)差都大到足以和直達聲區別開(kāi)，并能分辨出音節?；芈暤挠⑽拿Q(chēng)是Echo。

一定的混響對音質(zhì)有利，而回聲則只能破壞音質(zhì)，應絕對避免。

消除回聲的方法是進(jìn)行聲**處理。
