| Abstract: | The key technology of sound simulation is discussed in this paper,including spatial sound localization principle,roll-off distance model,Doppler effect and it's mathematical formula.Two APIs for sound simulation in virtual space are introduced.They are OpenAL and DireceSound.Some urgent questions are put forward according to the actual utilizationthe of vehicle driving simulator.The vehicle driving simulator with sound simulation system can provide auditory information.This is very helpful for drivers to know more about the surroundings,make wise judgement and take correct action. |
| Keywords: | sound simulation roll-off distance model doppler effect vehicle driving simulator |
