Implementation of 3D sound effect modeling technology based on vehicle driving simulator

Sound simulation system of virtual driving environment of auditory perception module, can make up for the lack of a single visual information to enhance the driver of the interactive virtual driving environment and the judgement of the spot realistic driving simulator, in order to better complete the training and driving training mission. This article discusses the virtual 3D positioning in the voice of principle, sound attenuation distance model, the Doppler effect and sound formula, and other key technologies on the two voices in the virtual space development kits OpenAL, DirectSound; under simulated driving For the practical application, given some applications and examples of relevant research which should be focus on in the field of staff have a certain value.
