Measuring a Dummy Head in Search of Pinna Cues
Extensive measurements were performed on a dummy head to investigate how the pinnae encode directional information. Transfer functions and impulse responses were examined to identify the features that contribute to localization. The reults suggest that near-vertical spectral edges play a major role. This finding sheds a new light on the relationship between the characteristics of the external car and the results of earlier psychophysical experiments by Blauert and by Hebrank and Wright.
