Abstract

This paper presents evaluation results of binaural auralization system which is based on image source and edge diffraction modeling. The auralization method is briefly overviewed and evaluation of the quality of auralization is performed both objectively and subjectively. As a case study the auralization of a lecture room is considered. The evaluation results show that the spatial properties of applied auralization are almost identical than obtained with real-head recording. However, timbre of the sound still differs between binaural auralization and real-head recording, especially with transient-like signals and at frequencies above 6-8 kHz. Despite, the evaluation results proved that plausible and natural sounding binaural auralization is possible with current auralization algorithms.
