| Popis: | Creating a realistic distance perception by means of spatial audio reproduction systems is not an easy task. Cues such as the ratio between the direct signal and the level of reverberation have been traditionally employed in stereo and surround systems. With the introduction of advanced spatial audio systems such as Wave Field Synthesis (WFS), it is possible to synthesize within the whole listening area the correct wavefront curvature produced by a virtual source located at a given distance. Some previous studies suggest that this curvature can be an additional cue for the listener to extrapolate distance. In this work, a subjective perceptual test has been carried out to compare the capabilities of WFS and Vector Base Amplitude Panning (VBAP) to reproduce accurately sound distances. Different variables were studied; type of sound, listening angle and reverberation at different distances. The analysis of the collected data suggests that WFS is better at reproducing distances than panning systems. |
