Variability in Perceptual Evaluation of HRTFs
Because appropriate head-related transfer functions (HRTFs) are key to binaural rendering, an evaluation is required to assess processing steps when individual HRTFs are not available. This study involving six subjects showed significant response variability in perceptual evaluations of HRTFs when subjects were asked to judge six sets of HRTFs, including individual HRTFs, with three different attributes. Insufficient reproducibility is problematic when trying to select nonindividual HRTFs. In order to minimize the effect of learning, adequate training should be provided. By using attribute evaluations and assessor selection, this study offers a methodology that might be used to produce consistent evaluations in commercial binaural syntheses.
