Frequency and amplitude estimation of the first peak of head-related transfer functions from individual pinna anthropometry

The first (lowest) peak of head-related transfer functions (HRTFs) is known to be a concha
depth resonance and a spectral cue in human sound localization. However, there is still no
established model to estimate its center-frequency F 1 and amplitude A 1 from pinna
anthropometry. Here, with geometries of 38 pinnae measured and their median-plane
HRTFs calculated by numerical simulation, linear regression models were evaluated in
estimating F 1 and A 1 from 25 concha depth and aperture measurements. F 1 was best …
