【摘要】：1998年由國家文化部負(fù)責(zé)開始籌建國家大劇院,經(jīng)過了長達(dá)8年的前期準(zhǔn)備工作時(shí)間,籌備辦公室進(jìn)行了大量基礎(chǔ)性調(diào)研工作,編寫了建設(shè)設(shè)計(jì)計(jì)劃書。2007年國家大劇院正式投入運(yùn)營,由于其特殊的地理位置,首都北京的天安門廣場西側(cè)路上,緊鄰人民大會(huì)堂,建院之初就被賦予了特殊的歷史使命,定位于做國際一流表演藝術(shù)中心。自此,全國各地迎來了一輪劇場建設(shè)的高潮。劇《全國專業(yè)劇場發(fā)展基本情況》的調(diào)查數(shù)據(jù)顯示,截止到2013年底,我國有專業(yè)劇場873家,2013年全年演出4.05萬場,觀眾總?cè)舜?229萬。但整體看,專業(yè)劇場存在總量不足、利用率不高、運(yùn)行機(jī)制不健全等問題。由于國家還沒有統(tǒng)一的專業(yè)劇場建設(shè)標(biāo)準(zhǔn),很多新建劇院都以大劇院為參照,并沒有考慮當(dāng)?shù)氐奈幕�、�?jīng)濟(jì)等方面的因素,設(shè)計(jì)出很多形式、功能類似的劇場,耗資巨大,利用率低,不具有個(gè)性化。在今后劇場建設(shè)的發(fā)展中,為避免環(huán)境、建筑、人力、資金等方面的過度消耗,筆者就音響設(shè)備設(shè)施系統(tǒng)方面進(jìn)行了充分的研究。從音響系統(tǒng)發(fā)展方向來看,多通道音響系統(tǒng)具有良好的前景。對(duì)目前世界范圍內(nèi)引用的三種多通道音響系統(tǒng)進(jìn)行了舉例介紹,并從理論上研究其關(guān)鍵技術(shù)核心——可變聲場。通過對(duì)可變聲場的仔細(xì)研究,分析了8個(gè)影響其結(jié)果的重要參量,掌握了可變聲場的技術(shù)方法,進(jìn)一步研究學(xué)習(xí)三種領(lǐng)先的聲場控制系統(tǒng),為應(yīng)用實(shí)踐做好基礎(chǔ)工作。筆者利用在大劇院工作的有利條件,將研究內(nèi)容結(jié)合實(shí)際情況,選擇了兩個(gè)項(xiàng)目進(jìn)行實(shí)際操作。先對(duì)歌劇院音響系統(tǒng)進(jìn)行了概括性介紹,再具體分析了使用多痛道擴(kuò)聲中的音響設(shè)計(jì)情況,并在實(shí)踐過程中總結(jié)問題,體會(huì)心得。同時(shí),還邀請(qǐng)了多位行業(yè)人士進(jìn)行了主觀評(píng)價(jià),從更專業(yè)的眼光評(píng)論可變聲場技術(shù)的實(shí)際應(yīng)用效果,使實(shí)踐更具有參考價(jià)值。當(dāng)然在研究過程中也發(fā)現(xiàn)了許多問題,不僅是技術(shù)本身,也有建設(shè)之初需要改進(jìn)的地方。最終是為了能夠建出更好的劇院來,不僅保量還要保質(zhì),更能為文化發(fā)展提供廣闊的空間。
[Abstract]:In 1998, the State Ministry of Culture was responsible for starting preparations for the construction of the National Grand Theater. After eight years of preparatory work, the Preparatory Office carried out a large number of basic research work. The National Grand Theater was officially put into operation in 2007. Due to its special geographical location, the Tian鈥檃n Men Square road west of the capital Beijing, next to the Great Hall of the People, was entrusted with a special historical mission at the beginning of its construction. Position to be the international first-class performing arts center. Since then, all over the country ushered in a round of theater construction climax. By the end of 2013, there were 873 professional theatres in China, with 40500 performances in 2013, with a total audience of 32.29 million. But on the whole, professional theater has some problems, such as insufficient quantity, low utilization rate and imperfect operating mechanism. Since the country has not yet established a unified standard for the construction of specialized theatres, many new theatres have taken the Grand Theater as a reference, and have not taken into account local cultural and economic factors. They have designed theatres of many forms and similar functions, which cost a great deal of money. Low utilization rate, not personalized. In order to avoid the excessive consumption of environment, construction, manpower, capital and so on, in the development of theater construction in the future, the author has carried on the thorough research on the sound equipment facility system. From the direction of sound system development, multi-channel sound system has a good prospect. In this paper, three kinds of multichannel sound systems used in the world are introduced, and the key technology, variable sound field, is studied theoretically. Through the careful study of the variable sound field, eight important parameters affecting the results are analyzed, the technical methods of the variable sound field are mastered, and the three leading sound field control systems are further studied, so as to do a good job of basic work for the application practice. The author makes use of the favorable condition of working in the Grand Theater and combines the research contents with the actual situation and chooses two projects to carry on the actual operation. This paper introduces the sound system of the opera house, and then analyzes the sound design in the use of multi-channel sound reinforcement, and summarizes the problems in the process of practice and experiences. At the same time, many professionals are invited to make subjective evaluation, and to comment on the practical application effect of variable sound field technology from a more professional point of view, which makes the practice more valuable for reference. Of course, many problems have been found in the research process, not only in the technology itself, but also in the initial construction needs to be improved. Finally, to build a better theater, not only to ensure quality, but also to provide a broad space for cultural development.
