Model for auditory localization

TLDR
Using a nonlinear regression program, the standard deviations of four of the auditory localization cues are estimated, allowing objective comparison of their relative accuracy.
Abstract
A mathematical model based on statistical decision theory has been devised to represent the human auditory localization task. The known localization cues have been represented as Gaussian random variables, so that their interaction in a given experiment can be analyzed (and predicted) along the lines of classical detection/estimation theory. We have applied this technique to most of the horizontal and vertical localization experiments reported in the literature during the past ten years, encompassing over 200 subjects and 20 000 trials. Using a nonlinear regression program we have been able to estimate the standard deviations of four of the auditory localization cues, allowing objective comparison of their relative accuracy. The resulting model provides a relatively good fit to the published results on 40 localization experiments.Subject Classification: [43]65.62, [43]65.58, [43]65.35.

Systems and methods for non-parametric processing of head geometry for hrtf personalization

TL;DR: In this paper, systems and methods for HRTF personalization utilizing non-parametric processing of three-dimensional head scans are described, and a personalized set of HRTFs for a user without having to extract specific geometric and/or anthropometric features from a 3D head scan of a user and from the training subjects in a database.

All-pole and all-zero models of human and cat head related transfer functions

TL;DR: Real Cepstrum analysis has been used to represent minimum phase HRTFs in the time domain and both models showed promising tractable systematic movements of the model poles and zeros with changes in sound source direction that may be used to build future models.

Use of Sonar Sensors with Human Infants

TL;DR: In this article, the authors used a sonar aid as a prosthesis for blind infants and children to represent space and spatial relations to themselves, based on a widely held belief that those who had never had visual experience lacked to an extraordinary degree the ability to represent spatial and spatial relationships to themselves.

Information-theoretic Performance Analysis of Azimuthal Localization for Spatial-Auditory Display of Beamformed Sonar Data

Jason Summers
TL;DR: An information-theoretic model of azimuthal localization is presented and the number of distinct source locations that can be encoded by a set of head-related impulse response functions (HRIR) is predicted in terms of information transfer as a function of the properties of the source signal and a quantization interval related to the level of internal perceptual noise.

Factors That Influence the Localization of Sound in the Vertical Plane

TL;DR: The ability of listeners to locate sound in the vertical plane was investigated and showed that for auditory stimuli to be located accurately, the stimulus must be complex, it must include frequencies above 7000 cps, and the pinna must be present.

Problem of localization in the median plane: effect of pinnae cavity occlusion.

TL;DR: It is shown that localization ability decreases with increasing occlusion, that it is better for signals in the anterior than in the posterior sector of the median plane, and that high‐frequency signal content is more important than the low.

Sound Pressure Generated in an External-Ear Replica and Real Human Ears by a Nearby Point Source

TL;DR: A rubber replica has a pinna, concha, and auditory meatus with dimensions comparable with those of real human ears, and pressure distributions in the canal and concha are given for M1, M2, and three other modes.
