英文摘要：

This article briefly introduces several uses in room environmental reverberation simulation method and expounded specific steps of using a method （IMAGE） to establish the room acoustics model. The simulation result shows that this method has flexible control reflective order, room dimension and microphone directional characteristics and has provided a feasible simulation method for building room reverberation model.
