Numerical Simulation of the Environmental Acoustic Characteristics of the Mogao Grottoes
摘要
Abstract
Noise may have some risk of damage to the diseased wall-paintings in the Mogao Grottoes in Dunhuang. In this paper, the environmental acoustic propagation law of the Mogao Grottoes was analyzed. A large number of finite element models of the inner caves with different shapes and sizes were established. The environmental acoustic characteristics of the inner cave were simulated and analyzed. For the purpose of protection of cultural relics, based on the outer or inner acoustic propagation characteristics of the Mogao Grottoes, a method of estimation of the maximum noise levels on the surface of the inner caves was presented. In this method, the maximum noise levels of the inner caves with different shapes and sizes can be estimated conservatively according to the monitored sound pressure levels of different frequencies outside the caves, so that the damage risk levels of the wall-paintings due to the environmental noise can be reasonably assessed. This work may provide a scientific basis for monitoring and prewarning technology for the wall-paintings protection of the Mogao Grottoes.关键词
