Objective and Subjective Comparison of Electrodynamic and MAP Loudspeakers for Wave Field Synthesis

Document Thumbnail

This article deals with the direct comparison of WFS rendering using either MAP or electrodynamic loudspeakers on an objective and a subjective level. Objective criteria are used to evaluate coloration and localisation cues that are perceived in an extended listening area. It is shown in a first listening test that the reduced spatial coherence of MAP loudspeakers partly explains the perceived differences between the two loudspeaker technologies. This "diffuse" behavior can be artificially produced on electrodynamic loudspeakers using a diffuse filtering. The proposed diffuse filtering may also limit rendering artifacts above the spatial aliasing frequency. Finally, it is shown in a second listening experiment that MAP loudspeakers favor distance perception compared to electrodynamic loudspeakers.
