To validate a head-tracking system in comparison to a loudspeaker-arrangement regarding perception of auditory source width (ASW), i.e. the horizontal extension of the auditory event (s), experiments by representing narrowband and broadband noise stimuli of chosen degrees of correlation were conducted. The excitation signals were presented by (i) pairs of loudspeakers and (ii) headphones with head-tracking in an anechoic environment. The evaluation by five trained subjects resulted in a good correspondence of the outcomes of the speaker and the head-tracking experiments, i.e. the head-tracking system had a negligible influence on spatial perception.
