Convention Paper

Analytical Interaural Time Difference Model for the Individualization of Arbitrary Head-Related Impulse Responses

Authors: Bomhardt, Ramona; Fels, Janina

AES Convention 137 · Paper 9131 · October 2014

Abstract

If dummy head or individual Head-Related Impulse Responses (HRIR) are used for binaural reproduction, either it can result in an incorrect perception of virtual sound sources or poses an enormous measurement effort. Therefore, in this paper a model is presented that helps to calculate the Interaural Time Difference by anthropometric head-data. By means of this Interaural Time Difference, the time of arrival of arbitrary HRIRs can be individualized. This model is compared with 13 individual measured HRIRs and the subjects' anthropometric head-data. The result of comparison leads to the conclusion that the model works well to individualize the Time of Arrival of an arbitrary HRIR.
