Inter-Subject Differences of Head Related Transfer Functions
2018 Joint Conference - Acoustics, 2018Examination of the characteristics of individual Head Related Transfer Functions (HRTF) requires the use of a specific measurement setup and procedure. This paper describes the design of a far field HRTF measurement setup in which the subject is continuously rotated towards a sound source placed at a certain elevation angle. Currently the system allows

Method for measurement of head related transfer functions
The Journal of the Acoustical Society of America, 2010Head Related Transfer Functions (HRTFs) of an individual are measured in rapid fashion in an arrangement where a sound source is positioned in the individual's ear channel, while microphones are arranged in the microphone array enveloping the individual's head.

Modeling head-related transfer functions with spherical wavelets
Applied Acoustics, 2019Abstract The head-related transfer function (HRTF) describes the sound transmission characteristics from a sound source to a listener’s ears. Recently, spherical harmonic decomposition has been extensively used for modeling the HRTF spatial patterns. Despite its advantage of approximating the coarse structure of HRTF spatial variations with modeling ...

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 ...

Calibration of measured head-related transfer function database
ICCAS 2010, 2010Some causes and those effects on measurement error of head-related transfer functions (HRTFs) were analyzed. Among different causes of error on HRTF measurement, change of exact location of a listener and corresponding position change of eartips are the most important.

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.

Head-related transfer function interpolation in azimuth, elevation, and distance
The Journal of the Acoustical Society of America, 2013Although distance-dependent head-related transfer function (HRTF) databases provide interesting possibilities, e.g., for rendering virtual sounds in the near-field, there is a lack of algorithms and tools to make use of them. Here, a framework is proposed for interpolating HRTF measurements in 3-D (i.e., azimuth, elevation, and distance) using ...

Head-Related Transfer Functions in the Near Field
1998Abstract : Although researchers have long recognized the unique properties of head-related transfer functions (HRTF) in the near field (within 1 m of the listener's head), virtually all of the HRTF measurements described in the literature have focused on source locations 1 m or farther from the listener.

Explaining individual differences in head-related transfer functions
The Journal of the Acoustical Society of America, 1999The fidelity of virtual auditory images is degraded by differences between the listener’s head-related transfer functions (HRTFs) and the HRTFs used to synthesize the virtual images. Middlebrooks (this meeting) argues that simple frequency scaling accounts for many of these individual differences.

Binaural range estimation using Head Related Transfer Functions
2015 IEEE International Conference on Multisensor Fusion and Integration for Intelligent Systems (MFI), 2015Inspired by the role of the outer ear to shape, direct, and focus sound waves, we present a binaural method for sound source range estimation in a three dimensional space to be deployed in a humanoid hearing system. The method is designed to allow robots to localize sound sources using only four microphones, two of which are placed inside the ear ...
