Lokki and Pulkki Evaluation of parametric auralization EVALUATION OF GEOMETRY-BASED PARAMETRIC AURALIZATION

This paper presents evaluation results of parametric auralization system. The auralization method, based on imagesource and edge diffraction modeling, is briefly overviewed and evaluation of the auralization quality is performed both subjectively and objectively. As a case study the auralization of a lecture room is considered with three different musical stimuli. The evaluation results show that with sound of a clarinet the auralizations are almost identical than obtained with recording the anechoic signal in a real space. However, the auralizations slightly differ from the recorded ones with transient-like signals, especially at low frequencies below 600 Hz. Despite, the evaluation results proved that plausible and natural sounding monophonic or binaural auralization is possible with the current auralization algorithms.
