Impact of non-individualised head related transfer functions on speech-in-noise performances within a synthesised virtual environment

Direct comparison of the impact of head tracking, reverberation, and individualized head-related transfer functions on the spatial perception of a virtual speech source.

A study of sound localization performance was conducted using headphone-delivered virtual speech stimuli, rendered via HRTF-based acoustic auralization software and hardware, and blocked-meatus HRTF measurements. The independent variables were chosen to evaluate commonly held assumptions in the literature regarding improved localization: inclusion of head tracking, individualized HRTFs, and ear...

Toward orthogonal non-individualised head-related transfer functions for forward and backward directional sound: cluster analysis and an experimental study.

Individualised head-related transfer functions (HRTFs) have been shown to accurately simulate forward and backward directional sounds. This study explores directional simulation for non-individualised HRTFs by determining orthogonal HRTFs for listeners to choose between. Using spectral features previously shown to aid forward-backward differentiation, 196 non-individualised HRTFs were clustered...

Subjective Selection of Non-individual Head-related Transfer Functions

The individualization of head-related transfer functions (HRTFs) for virtual acoustics is a key technique for the optimization of the directional reproduction. This paper presents a subjective selection method for a fast, individual selection of one HRTF from a catalogue of non-individual ones. The selection method gives random access to sounds filtered with the HRTFs. In a first selection step...
