关于不良建筑声学环境的电声解决方案——以长安壹号会议厅为例

不良的建筑声学环境存在着许多声音缺陷，如声聚焦、颤动回声、声影等。可以通过恰当的电声设计来弥补这些缺陷，以达到相对理想的声音效果。首先使用先进的声学设计软件进行声场的模拟设计，然后选择合适的电声设备（如数字音箱）来解决实际建筑上存在的声学缺陷。论述了常见的各种建筑声学缺陷，并对其进行了分析，以及如何通过选择合适的电声方案来解决这些缺陷。

Electroacoustic Solution in Bad Architectual Acoustics Environment——Taking Chang＇ an No. 1 Conference Hall as an Example

Architectural acoustics environment has many defects of sound, such as sound focusing,muhiecho, acoustic shadow etc. These deficiencies can be made up by appropriate electroacoustic design,in order to achieve relatively ideal sound effects. Firstly, advanced acoustic design software is used to simulate the design of sound field,then the appropriate electroacoustic equip- ment （ such as digital speakers） is selected to solve acoustic defects in actual construction. A variety of common defects of archi- tectural acoustics is discussed,and how to choose suitable electroacoustic scheme to solve these defects is analyzed.
