Image of FIG. 1.
FIG. 1.

Sphere scattering model with a hemispherically divided surface covering used to approximate the contribution of hair to the auditory percept. The black dot illustrates the pinna location.

FIG. 2.

Spatial reference planes and relative source rotation angles (starting from 0°). For the symmetric hair and pinna alignment used, the frontal plane is identical to the azimuth plane with the appropriate angular remapping.

FIG. 3.

Changes in the right ear head-related transfer function (HRTF) due to the addition of a hemispherical hair covering with a specific acoustic impedance of , . The left panels display the azimuthal HRTF and the right panels the median HRTF. The upper panels correspond to a rigid sphere, the central panels include a hemispherical hair covering, and the lower panels show the decomposed HRTF change due to the hair covering.

Azimuthal circumferential surface pressure magnitudes at for eight angles of source incidence for a spherical head with a hemispherical hair covering (where , ). The black dot on the polar plots corresponds to the pressure at the right ear and the dashed lines illustrate the polar axes and the unit circle for reference.
