Simulation of high-resolution near-field HRTFs

The measurement of near-field head-related transfer functions (HRTFs) is challenging since a loudspeaker does not present a point source, and  the measurements can include unwanted  reflections between the head and the loudspeaker. A simulation based acquisition of HRTFs, however, allows an ideal point-to-point mapping from near-field source points to the measurement point at the entrance of the blocked  ear-canal.  Using the principle of reciprocity, a fast boundary element method can generate HRTFs for tens or hundreds of thousands source points. In addition, the HRTFs can be personalized by using 3d scanned models of head and pinnae. We introduce a simulation based approach for generating personalized  near-field HRTFs with high spatial resolution.
