When acoustical problems occur in architectural spaces acousticians are often requested to help. The help is often complicated by very different knowledge in acoustics and problems in communication between architect, musicians and acousticians. Auralization of sound sources is considered to be a powerful tool to solve the problem, making acoustic information accessible for hearing. The present research assessed the quality of the output of different simulation procedures by subjective assessment of similarity with a reference sound, considering different perceptual dimensions (localization, reverberation, and timbre). The reference sound was obtained by binaural recording in the room that was auralized using ray-tracing, mirror sources or a hybrid pyramid tracing method. Two different types of sound sources, human speech and a guitar, were auralized. The results show that the subjective quality of the simulation procedure depends on the type of sound source and the perceptive dimension that was assessed. In general the mirror source method performed best for localization of speech, whereas ray-tracing was the preferred method for the guitar sound. Overall mirror sources also outperform the other methods when good localization is required. Independent from the source the hybrid method was considered the best for the reverberation dimension. |
