Horizontal Plane HRTF Reproduction Using Continuous Fourier-Bessel Functions
TLDR
In this paper, a separable representation consisting of a Fourier Bessel series expansion for the spectral components and a conventional Fourier series expansion of the spatial dependence is proposed to reproduce the Head Related Transfer Function (HRTF) in the horizontal auditory scene.Abstract:
This paper proposes a method to reproduce the Head Related Transfer Function (HRTF) in the horizontal auditory scene The method is based on a separable representation which consists of a Fourier Bessel series expansion for the spectral components and a conventional Fourier series expansion for the spatial dependence The proposed representation can be used to predict HRTFs at any azimuth position and at any frequency sampling point from a finite number of measurements Implementation details are demonstrated in the paper Measured HRTFs from a KEMAR manikin and analytically simulated HRTFs were used to validate the fidelity and predictive capabilities of the method The average mean square error for model reconstruction is less than two percentread more

Headphone simulation of free-field listening. II: Psychophysical validation
TL;DR: Listeners reported the apparent spatial positions of wideband noise bursts that were presented either by loudspeakers in free field or by headphones, with the aim of duplicating, at a listener's eardrums, the waveforms that were produced by the free-field stimuli.

A model of head-related transfer functions based on principal components analysis and minimum-phase reconstruction.
TL;DR: Free-field to eardrum transfer functions (HRTFs) were measured from both ears of 10 subjects with sound sources at 265 different positions and revealed that the HRTFs can be modeled as a linear combination of five basic spectral shapes (basis functions), and that this representation accounts for approximately 90% of the variance in the original HRTF magnitude functions.
