COMPARATIVE STUDY ON HRTFS OF SIMPLIFIED DUMMY HEADS AND SUBJECT LISTENING EVALUA- TION
Lin Yang, Zhonghua Fu, Ling Tang · 2014
The HRTFs of a standard Chinese dummy head and its different simplified versions are calculated and compared. Numerical comparisons are performed to analyze the influences of different head simplifications. Seven different simplified artificial heads are modeled based on the standard Chinese dummy head , where the head is simplified as ellipsoids of different sizes, including head height, head breadth, and head length as in GB/T 23461-2009[S], and the pinnae remain unchanged. All HRTFs are calculated using the boundary element method. The relation between numerical errors and listening distortions are highlighted.
