【摘要】 大型厅堂音质设计过程中,控制回声一直为声学设计者所关注。如何在设计之初准确确定厅堂内产生回声的反射面,并采取恰当的处理方式进行合理控制,已经成为整体声学设计的关键问题之一。本文利用声学模拟软件对中科院研究生院礼堂进行声场模拟计算,确定出厅堂内产生回声的反射面,并采用脉冲响应函数的测试方法,对该礼堂进行实际测试比较,对出声场回声的模拟和测试方法进行探讨。更多还原

【Abstract】 Echo control is one of the most important things in the building design. To find the surface which brings the echo in the Graduate University of Chinese Academy of Sciences hall, the sound field is calculated by the commercial software Raynoise and the reflection surface is also been detected by using impulse response measurement. Compared the measurement results with the results obtained by Raynoise software, the impulse response measurement of the echo in the hall is discussed.更多还原
