Abstract

<p>This paper presents construction of acoustic simuration method for considering absorbtion effect and applying this method to moving sound source problem. The CIP method using adaptive mesh refinements is employed for the descretization of wave equation, and impulse response analysis which can reproduce various noise problems is adopted.For considering absorbtion effect, Rayleigh model is introdeced. For considering moving sound source, time-variant convolution. As an example, we compute three-dimensional acoustic problem with absorbing material sound barrier and make auralization by using VR thecnology.</p>
