DEVELOPEMENT OF AN EXPERIENCE-BASED AIRCRAFT NOISE EVALUATION SYSTEM USING VIRTUAL REALITY TECHNOLOGY

Abstract

 This paper presents an experience-based aircraft noise evaluation system using virtual reality technology. The computation of noise level is performed by the geometric acoustic theory and the effect of the directivity of sound is considered to improve the numerical accuracy. The system is developed for the useful tool to evaluate the soundproof measurements in the indoor and outdoor around the airport. The present system is applied to several examples in order to investigate the validity and efficiency of the method. The computed results are compared with the measurement data in both real space and virtual reality space.
