Individualization of Head-Related Transfer Function for Three-Dimensional Virtual Auditory Display: A Review

Head-Related Transfer Functions and Virtual Auditory Display

3D sound image control by individualized parametric head-related transfer functions

It is well known that the listener’s own head-related transfer functions (HRTFs) provide accurate 3D sound image localization. However, the HRTFs of other listeners often cause degradation of localization accuracy. Though the 3D auditory display with a head-motion trucker, which provides a dynamic spatial cue to a listener, improves the rate of front-back confusion, this dynamic cue is not enou...

Toward HRTF personalization: an auditory-perceptual evaluation of simulated and measured HRTFs

Sound localization tests were carried out with two subjects using a Virtual Auditory Display (VAD) to determine the intersubject effects on localization accuracy, of employing either acoustically measured or Finite Difference Time Domain (FDTD)-simulated Head Related Transfer Functions (HRTFs). Results indicate that the simulated HRTFs were able to yield comparable localization performance and ...

Simulation, Visulization and Perception of Sound in a Virtual Environment Using Beamforming

This paper describes a method to visualize and localize the sound that is simulated within a virtual environment using beamforming. The use of an acoustic camera along with noise image software as a short introduction to beamforming method is demonstrated. Furthermore, the transition from the three-dimensional sound recording to the three-dimensional virtual acoustic mapping, visualization and ...

Free-Field Virtual Psychoacoustics and Hearing Impairment: Paper ICA2016-53 Measurement of pinna flare angle and its effect on individualized head-related transfer functions

Head-related transfer functions (HRTFs) are essential to the researches of binaural hearing and applications of virtual auditory display. Generally, HRTFs vary with frequency as well as source position relative to head centre. They also depend on anatomical structure and parameters of individual subject. The related anatomical parameters mainly include the dimensions of head and pinnae, and the...
