Abstract: Numerous studies have shown that on the interaural time difference (ITD) depends on the angle of incident of the sound wave as well as the individual’s anthropometric dimensions. When a geometric model is used for determining ITD, exact anthropometric head dimensions are desirable. However, measuring anthropometric dimensions always introduces uncertainties that are primarily caused by the projection from three-dimensional head shape to one-dimensional measures. This paper describes a listening experiment to derive the direction-dependent just-noticeable time deviation from an individual ITD. The determined threshold is then utilized to calculate the required measurement accuracy of the input dimensions of an ITD model exemplar. A feasibility study is presented in which four required head dimensions of 17 subjects are automatically measured on three-dimensional head models. These models are determined using an RGBD sensor and software for three-dimensional surface reconstruction. The accuracy of the automatically determined anthropometric head dimensions is evaluated by comparing them to dimensions obtained from magnetic resonance imaging scans.
