Abstract
Presented at the 21st International Conference on Auditory Display (ICAD2015), July 6-10, 2015, Graz, Styria, Austria.In the absence of a well suited measure for quantifying binaural data
variations, this study presents the use of a global perceptual distance
metric which can describe both HRTF as well as listener similarities.
The metric is derived based on subjective evaluations of binaural
renderings of a sound moving along predefined trajectories in the
horizontal and median planes. Its characteristics and advantages in
describing data distributions based on perceptually relevant attributes
are discussed. In addition, the use of 24 HRTFs from two different
databases of origin allows for an evaluation of the perceptual impact of
some database-dependent characteristics on spatialization. The effectiveness
of the experimental design as well as the correlation between
the HRTF evaluations of the two plane trajectories are also discussed
