Abstract

A study was carried out in order to determine major cues for the perception of negative elevation in the median plane. Extensive analysis focusing on the differences of negative elevation angles to 0° in the median plane was conducted using multiple individual and KEMAR HRTF datasets. Based on the analysis, a parametric equalisation model using two notches and one peak is proposed. This model has been applied to a white noise stimulus in a listening test using headphones. The results suggest that the proposed method could effectively create the impression of a negatively elevated image.
