Abstract
<p>This paper presents a numerical method for sound field analysis based on fast multipole boundary element method. The impulse response analysis is usefully introduced to realize the efficient numerical simulation. The present method is applied to the sound field analysis around the sound insulation wall with complicated shape. The noise evaluation system is also developed for the use of immersive VR device and head mounted display. The system exposes to the users the computed noise level with both the auditory information using sound source signal and the visual information using CG image. In order to investigate the validity and efficiency of the method, the present method is applied to the construction noise problem and the numerical results are compared with the observed results in VR space.</p>
