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.read more

Predicting the Precision of Elevation Localization Based on Head Related Transfer Functions
Sascha Dick,Jürgen Herre +1 more
TL;DR: A method to predict localization accuracy is presented, based on analysis of the gradient of HRTF log-spectral differences for elevation positional changes, which shows good agreement with results from subjective localization experiments reported in literature.

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
E. A. G. Shaw,R. Teranishi +1 more
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.
