Head-Related Transfer Function (HRTF)

Head-Related Transfer Function (HRTF) A characteristic of the human hearing mechanism that allows us to localize sound sources in three-dimensional space. Many physical factors are involved: ear spacing, the frequency-response detecting ability of the inner ear, the shape of the outer ear, and even the shape of the head itself. Indeed, the HRTF is a surprisingly complicated function of four variables: three different space coordinates, as well as frequency. In spherical coordinates, for…
