An Efficient Auralization of Edge Diffraction

摘要

Principles and implementation of efficient auralization of edge diffraction is presented. A calculation principle for the impulse response from an edge is reviewed. This technique is integrated into an acoustic modeling system which is based on the image source method. For auralization purposes a low-order digital filter for each diffracting edge is designed which implements the diffraction phenomenon efficiently and is suitable for parametric auralization. Finally, examples of filter designs are presented.
