警官(guan)學(xue)院大(da)講堂是滿足文藝(yi)演出、主(zhu)題(ti)晚會、音樂會、召(zhao)開會議(yi)等現場擴(kuo)聲綜(zong)合(he)性廳堂。本音響系統設計方案(an)為各種擴(kuo)聲形式提供(gong)優良(liang)的音頻環境，產(chan)生優秀的音質效果。

我司經充分理解圖紙及相應要(yao)求后，以全面(mian)滿足廳堂的(de)功能要(yao)求為原則，在設計的(de)過程中經過仔細的(de)考慮和(he)分析(xi)，找(zhao)到并(bing)形成了一個適合警官學院大講堂的(de)音響系統方案。

1、音響系統的需求定位與功能分析

根(gen)據警(jing)官學院大講(jiang)堂實際使用中(zhong)的功能(neng)需求，在設(she)計過程中(zhong)對該系統作如下基本定位：

！滿足文(wen)藝(yi)演(yan)出、主(zhu)題(ti)晚會的擴聲要(yao)求；

！?滿(man)足召開會議的擴聲要求

！滿足音樂演奏的(de)擴聲要求

根據多功能廳的使用需(xu)求定位，我們確定了本音響(xiang)系統的主要功能是：

1).??改善(shan)語(yu)言清(qing)晰(xi)度和音樂明晰(xi)度；

2).??提高(gao)節目(mu)源的響度，擴展節目(mu)源的動態；

3).??改進不同(tong)演出中的聲平(ping)衡；

4).??具有(you)良好的聲還原特性（即(ji)保真度）；

5).??具有極(ji)佳的聲像(xiang)自(zi)然(ran)度（即聲像(xiang)一致性(xing)）；

6).??在無(wu)樂(le)隊(dui)演奏時重放伴奏音樂(le)；

7).??可將(jiang)部分節目信(xin)號存儲和預置程序以簡化操作；

2、音響系統的擴聲形式

根據相(xiang)關(guan)要求，并依據對當前(qian)國(guo)內外各種(zhong)多功能廳(ting)堂音(yin)響(xiang)系(xi)統的(de)調查研究，確定該廳(ting)堂擴聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)系(xi)統采用(yong)左(zuo)、中、右三聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)主(zhu)(zhu)擴聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)與(yu)(yu)多點(dian)位補聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)相(xiang)結合的(de)擴聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)方(fang)式(shi)，觀(guan)眾(zhong)廳(ting)左(zuo)、中、右三個(ge)(ge)主(zhu)(zhu)擴聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)，每(mei)個(ge)(ge)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)基本獨立(li)覆蓋(gai)全場，在觀(guan)眾(zhong)廳(ting)設置多點(dian)位補聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)揚聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)，通(tong)過提高直(zhi)達(da)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)與(yu)(yu)混響(xiang)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)能比，從而提高語(yu)言清晰(xi)度，使得整(zheng)個(ge)(ge)音(yin)響(xiang)系(xi)統能夠兼顧(gu)左(zuo)、右聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)立(li)體(ti)(ti)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)，左(zuo)、中、右三聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)立(li)體(ti)(ti)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)，單(dan)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)擴聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)等(deng)多種(zhong)擴聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)形式(shi)。所有(you)揚聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)均使用(yong)有(you)源一體(ti)(ti)化揚聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)，保(bao)證了功放(fang)與(yu)(yu)揚聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)間的(de)一致性(xing)。

舞臺音頻系統選型：

揚(yang)聲(sheng)器是(shi)音響(xiang)系(xi)統(tong)中最重要的(de)(de)組成(cheng)部(bu)分。由于電子(zi)(zi)技(ji)術的(de)(de)發展，聲(sheng)系(xi)統(tong)中電子(zi)(zi)設備(bei)的(de)(de)頻率響(xiang)應與(yu)相位(wei)響(xiang)應上的(de)(de)處理已達(da)到很高水平，影響(xiang)音響(xiang)系(xi)統(tong)還原性能的(de)(de)主(zhu)要瓶(ping)頸是(shi)換能器的(de)(de)失(shi)真，因此揚(yang)聲(sheng)器的(de)(de)選(xuan)用是(shi)對最終(zhong)還音質量影響(xiang)最大、最有決(jue)定(ding)性的(de)(de)一(yi)個環(huan)節。
