Personalizing head related transfer functions for earables
Proceedings of the 2021 ACM SIGCOMM 2021 Conference, 2021Head related transfer functions (HRTF) describe how sound signals bounce, scatter, and diffract when they arrive at the head, and travel towards the ears. HRTFs produce distinct sound patterns that ultimately help the brain infer the spatial properties of the sound, such as its direction of arrival, 𝜃.

A bottle model for head-related transfer functions
Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002We describe a parsimonious model for the direction-dependent transfer function of the pinna. The model describes the transfer function with reference to resonators located in particular physical positions relative to the ear canal. The purpose of the work is to provide a parametric model that permits identification with moderate data-gathering, and ...

Head-related transfer functions of the Rhesus monkey
Hearing Research, 2000Head-related transfer functions (HRTFs) are direction-specific acoustic filters formed by the head, the pinnae and the ear canals. They can be used to assess acoustical cues available for sound localization and to construct virtual auditory environments.

Considerations Regarding Individualization of Head-Related Transfer Functions
2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018This paper provides some considerations regarding using individualized head-related transfer functions for rendering binaural spatial audio over headphones. It briefly considers the degree of benefit that individualization may provide. It then examines the degree of variation existing within the ear morphology across listeners within the Sydney-York ...

Transforming the head-related transfer functions
The Journal of the Acoustical Society of America, 1997Auditory and visual localization of a real sound source under both natural and artificial listening conditions were examined. Five subjects were employed in a visual search task paradigm which contained some conditions that were aurally aided. The aurally aided conditions utilized white noise, emitted at the subjects horizon, from a single speaker at ...

On the generalization of accommodation to head-related transfer functions
The Journal of the Acoustical Society of AmericaTo date, there is strong evidence indicating that humans with normal hearing can adapt to non-individual head-related transfer functions (HRTFs). However, less attention has been given to studying the generalization of this adaptation to untrained conditions.

Head related transfer functions for KEMAR.
The Journal of the Acoustical Society of America, 2009The head related transfer functions (HRTFs) for KEMAR for a number of ear pinnas of different sizes and hardnesses have been measured. Right and left ear differences on KEMAR as well as change in HRTFs over the last 40 years will be reported along with data for the ITU - Type 3 and the IEC 60959 standardized pinna.

Distance-dependent Modeling of Head-related Transfer Functions
ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019In this paper, a method for modeling distance dependent head-related transfer functions is presented. The HRTFs are first decomposed by spatial principal component analysis. Using deep neural networks, we model the spatial principal component weights of different distances. Then we realize the prediction of HRTFs in arbitrary spatial distances.

A localization algorithm based on head-related transfer functions
The Journal of the Acoustical Society of America, 2008Two sound localization algorithms based on the head-related transfer function were developed. Each of them uses the interaural time delay, interaural level difference, and monaural spectral cues to estimate the location of a sound source. Given that most localization algorithms will be required to function in background noise, the localization ...

Head-related transfer function synthesis for immersive audio
1998 IEEE Second Workshop on Multimedia Signal Processing (Cat. No.98EX175), 2002Immersive audio systems are being envisioned for applications that include teleconferencing and telepresence; augmented and virtual reality for manufacturing and entertainment; air traffic control, pilot warning, and guidance systems; displays for the visually- or aurally-impaired; home entertainment; distance learning; and professional sound and ...
