Abstract

Research has shown that personalized spatial cues used in 3D sound simulation lead to an improved perception and quality of the sound image. This paper introduces a simple method for photographically extracting the size of the head, and proposes a fitted spherical head model to more accurately predict Interaural Time Differences (ITD). Head-Related Impulse Responses (HRIR) were measured on eleven subjects, and ITDs were extracted from the measurements. Based on a photograph taken of each subject's face, the distance between the ears was measured and used to model a subject's personal ITDs. A head model is proposed that adjusts the spherical head model to more accurately model ITDs. Acoustic measurements of ITDs are then compared to the modelled ITDs demonstrating the effectiveness of the proposed method for photographically extracting personalized ITDs.
