| dc.description.abstract | In the current study, we present full-spherical high resolution head-related transfer function (HRTF) datasets of the head and torso simulator FABIAN including data for multiple head-above-torso orientations within a typical horizontal rotation range of ± 50 degrees. While the first dataset was measured acoustically using sequential swept sines, the second one was modeled numerically using the boundary-element method accelerated with the fastmultipole method (FMM-BEM). Comparison of magnitude spectra revealed a good agreement at mid and high frequencies, but increasing differences at frequencies below 200 Hz which could be attributed to the limited frequency range of the measurement loudspeaker. Additionally, an analysis of times of arrival (TOA) revealed differences which were presumably caused by mechanical inaccuracies of the physical measurement setup. Consequently, by using the modeled data as a reference, in the measured head-related impulse responses (HRIRs), we corrected TOAs by fractionally delaying, and extrapolated the low frequency range. | en |
