摘要
The present invention is provided in virtual reality to predict noise generated in real space to users, A spatial database in which 3D information on noise realization spaces including buildings and roads is bui A noise library in which information on noise sources including vehicles is bui When a user wearing a virtual reality device including an HMD device moves in a virtual space, an output that implements the noise realization space in 3D on the virtual reality device according to the moving position and gives the noise generated from the noise source with size and direction Noise control module; It is composed including, The user provides a virtual reality-based road traffic noise environment simulation system, characterized in that the user directly experiences visual information and audible information on a noise source from a first-person view. And by using the virtual reality-based road traffic noise environment simulation system, (1) a connection step of the user wearing the HMD device and accessing a virtual reality system; (2) a setting step of selecting 3D information provided by the spatial database, selecting a noise source provided by the noise library, and setting various conditions; (3) an output step of outputting visual information and audible information about a noise source to the HMD device through the output noise control module; It provides a noise simulation method using a virtual reality-based road traffic noise environment simulation system, characterized in that configured to include.
