Abstract

Head-related transfer functions (HRTFs) were measured on 40 human subjects for 97 directions of sound incidence, covering the entire sphere.Individual HRTF data for the median, horizontal, and frontal planes are presented in the frequency domain.Measurements were made synchronously at both ears, thus making the time representations, that is, the head-related impulse responses (HRIRs), valid also when interaural time differences are considered.The measurements were made at the entrance to the blocked ear canal.Sound at this point contains full spatial information, and the interindividual variation is lower than at the open ear canal.
