Study of 3D Sound of Airport Crash Fire Vehicle Simulator

Abstract

Airport crash fire vehicle simulator is an important device that is used in training of the airport firefighters, which has advantage of safe, energy saving and decreasing training cost. Sound system is an important part of airport crash fire vehicle simulator, which provides voice message to training personnel, which can make training personnel have immersed sense. Based on the principles of sound source position to analyze the different physical structure of the human body (head, torso, pinna) the impact of sound localization, the establishment of head-related transfer function model, using the model of the sound source, filtering, delay processing, and virtual sound source. And we have tested and verified with listening experiment.
