飞行模拟器三维声音仿真及实现
Simulation and realization of 3D sound for flight simulator
摘要
Abstract
In order to obtain the sense of reality and immersion for flight simulation,it is very necessary to recur three dimensional（3D） sound field environment of aircraft cockpit.On the basis of determining the sound events to be simulated by a flight simulator,the frequency spectrum analysis and time-frequency analysis were used to analyze the sound data acquired from the pratical field to find out the basic sound characteristics of each component for an aircraft.And then the sound sources to be used in the simulation were extracted from the original sound record with LMS adaptive filtering and various methods for signal processing.Based on the consideration of both system integration and performance,a new component scheme for sound simulation system was proposed,and an object-oriented program development method was used for software realization.The key technologies for researching and developing 3D sound simulation system,namely sound real-time synthesis and spatialization technologies,were particularly discussed.The developed 3D sound simulation system was integrated in a Boeing 737-800 flight simulator in laboratory.A large amount of flight tests prove that the proposed development method is effective and feasible.关键词
