岜沙苗寨铜鼓坪声场仿真模拟研究

SIMULATION STUDY ON THE SOUND FIELD OF TONGGUPING IN BASHA MIAO VILLAGE

苗族铜鼓坪既是传统的观演空间,又是重要的祭祀空间,因此其在民族文化中具有着重要的艺术审美价值与精神价值。本文选取一个典型的铜鼓坪作为研究对象,运用ODEON软件建立了仿真模型,以混响时间T30、早期衰变时间、语言明晰度C80的值作为评价声场特性的指标,探讨了声场仿真在传统开敞空间的科学性与实用性。

The Miao Tongguping is not only a traditional performance space,but also an important sacrifice space.It has important artistic aesthetic value and spiritual value in their culture.This paper selects a typical Tongguping as the research object,and uses ODEON software to establish a simulation model.The reverberation time T30,the early decay time,and the value of language intelligibility C80 are used as indicators to evaluate the characteristics of the sound field.This paper discusses the scientificity and practicability of sound field simulation in the traditional open space.
