The perceptual refinement of dynamic binaural synthesis has been subject to research for the past years. The basic principle relies on head-related transfer functions (HRTFs), which describe the directional filtering caused by the head, pinna, and torso. However, most systems are based on far-field HRTFs and therefore ignore the acoustical specifics of near-field sound sources. One reason might be that full spherical near-field HRTF sets are rarely available. In this paper, we present an HRTF set of a Neumann KU100 dummy head. The set is freely available for download and contains post-processed impulse responses, captured on a circular and full spherical grid at sound source distances between 0.25m and 1.50 m. In a subsequent listening experiment using dynamic binaural synthesis, we investigated if the captured binaural cues affect estimated distance of a virtual sound source. The set is useful for various spatial audio applications where nearby virtual sound sources are required, such as auditory displays.
