Abstract: This paper focuses on the environmental acoustic effect simulation and related technologies, and an environmental acoustic effect simulation system based on acoustic measurement modeling method is developed. In order to get the model of environmental acoustic effect in a room, assuming the model is linear and recognizing the impulse response of the model using correlation analysis method. The Interpolation technique in frequency domain is employed to calculate the room impulse response in the given condition. The software architecture, main modules and key technologies of the system are also presented. Experimental results demonstrate that the system can well simulate room environmental acoustic effect. The system can be applied to various virtual reality systems.

Key words: virtual reality, environmental acoustic effect, correlation analysis
