Modeling of non-individualized head-related transfer functions for nearby sources
The minimum realization method was used to model the non-individualized head-related transfer functions (HRTFs) of B&K HATS (Head And Torso Simulator) type 4128C measured with a special acoustic point-source positioned at various distances within 1 m from the head center for 3D sound implementation in hand-held devices such as MP3 players and cellular phones. The interaural time delays (ITDs) a...
متن کاملAre spectral elevation cues in head-related transfer functions distance-independent?
Since its title, this paper addresses one of the still open questions in sound localization: is our own perception of the elevation of a sound source affected by the distance of the source itself? The problem is addressed through the analysis of a recently published distance-dependent headrelated transfer function (HRTF) database, which includes the responses of a single subject on a spatial gr...
متن کاملEffects of Spectral Manipulation on Nonindividualized Head-Related Transfer Functions (HRTFs)
BACKGROUND Directional sounds simulated using nonindividualized head-related transfer functions (HRTFs) often result in front-back confusion. OBJECTIVE This study was designed to examine how manipulating these nonindividualized HRTF spectra can reduce front-back confusion in headphone-simulated directional sounds. METHOD HRTFs of six ear-level directions were studied (angles of 0 degrees, 4...
متن کاملInterpolating Head Related Transfer Functions
This paper describes the interpolation of head related transfer functions (HRTFs) for all directions. The interpolation of HRTFs enables us to reduce the number of measurements for new user’s HRTFs, and also reduce the data of HRTFs in auditory virtual systems. A linear interpolation and the spline interpolation are evaluated and the advantages of both methods are clarified. The interpolation m...
متن کاملModeling Head Related Transfer Functions
Head Related Transfer Functions (HRTF’s) characterize the transformation of a sound source to the sounds reaching the eardrums, and are central to binaural hearing. Because they are the result of wave propagation and difiraction, they can only be approzimated by finitely parameterized filters. The functional dependence of the HRTF on azimuth und elevation is described, the requirements for a mo...
