VERIFICATION OF THE INFLUENCE OF PSEUDO IMPULSE WAVEFORM AND MESH RESOLUTION ON AURALIZATION

Abstract

This paper verifies the influence of pseudo impulse waveform and mesh resolution on auralization. For the pseudo impulse, we employed the pseudo impulse derived from the equation of Lubich's Convolution Quadrature Method and Gussian pulse. In order to investigate the accuracy and frequency characteristics, a 3D wave propagation analysis is performed. We verified the sound data obtained by convolution of sound source and impulse response obtained by the different pseudo impulse and mesh resolution. As a results, the pseudo impulse obtained by Lubich's CQM is suitable for the noise simulation based on the impulse response analysis.
