Fast measurement system for spatially continuous individual HRTFs

The head-related transfer function (HRTF) describes the individual perception of sound for different angles of incidence of a sound wave. The directional cues contained in the HRTF are introduced by reflection and diffraction of the sound wave at head and torso and are highly individual [1]. When hearing a binaural signal synthesized via a generic HRTF – deviating from the listener’s HRTF – localization is degraded, especially for the height impression as these deviations are is strongly related to the individual geometry of the pinna. As lateral impression relies on binaural cues, hearing with a generic HRTF will produce an overshooting or undershooting of the localization.
