【摘要】 本文是在厅堂可变混响的基础上,追踪国内外相关资料,对现有可变混响进行深入的研究。厅堂建筑中存在着多种的耦合空间,这些耦合空间给厅堂类建筑的音质带来了一定的影响,并易被建筑师和声学设计师所忽略。本文就是以这些耦合空间为主要研究对象,分析其本身的特性在可调混响及其音质效果等方面对厅堂产生的影响,从而使厅堂的混响时间“最佳”,并避免产生声缺陷。利用声学模拟软件EASE对厅堂存在的耦合空间进行了模拟,同时也对耦合空间本身不同的特性(容积的大小、壁面材料的吸声性能、耦合空间的位置、耦合空间的开口形式等)进行了模拟。通过实例,对天津大学建筑学院建筑技术研究所进行了测试与模拟,验证EASE模拟的准确性。通过对耦合空间计算机模拟结果的分析,得出了耦合空间在可调混响方面的定量化及其音质的影响,从而证明利用耦合空间可以代替传统的可调混响结构形式,实现厅堂的“多功能”用途,具有很好的经济性。同时,研究厅堂建筑的耦合空间,必须考虑周围环境噪声和设备噪声的影响,还要结合该建筑的内部装修共同考虑。更多还原

【Abstract】 This paper studied Adjustable Reverberation Time(ART) deeply bytracing and synthetizing internal and overseas current corelativeinformation.Many kinds of coupled rooms are in a hall,which impact the qualityof tone in some degree.These coupled rooms are easy to be neglected byarchitects and acoustics engineers.This paper take these coupled rooms as research objects.Thereverberation time is optimized ,and the accoustic defects are avoidedby analyzing the charcaters of the coupled rooms on ART and its effectson tone quality of a hall.The coupled rooms in the hall are simulated by the software EASE,atthe same time the characteristic of that,including cubage,soundabsorption property of the wall material,position and the orifice formof the coupled rooms,are also simulated.For instance,the accuracy of thesimulation by EASE was tested through the testing and simulation of theArchitecture Technology Graduate School of Architecture DepartmentinTianjin University.The impacts of the quality of tone by the coupledrooms on the fix quantify can be made sure through the analyzing of thecomputer simulation result of the coupled rooms.Utilizing coupled roomsas substitute for the traditional ART structure to achieve themulti-function of the hall is very economical can be concluted.The noises of surroundings and equipments must be take in account atthe same time in studying coupled rooms,as well as fitments in the hall.更多还原
