Abstract
In this paper we propose a method to customize a spherical head model for binaural sound rendering based on the listener’s anthropometry.
Interaural level difference (ILD) information from
a HRTF database is used to subjectively tune the radius parameter
of the spherical model so as to best fit individual measures.
Multiple linear regression on anthropometric data is performed,
yielding a closed formula relating the three head dimensions to the
ILD-optimized radius. The effectiveness of the proposed radius
estimation method in predicting the correct ILD with a spherical
model is compared to that of alternative methods from the literature. Results show that the average spectral distortion between experimental and predicted ILDs with our method is significantly lower than with other estimation methods for lateral source locations.
The proposed customization approach provides substance
towards the development and evaluation of personal auditory displays for binaural virtual acoustics.
