Abstract :
Much effort has been put on the head-related transfer function (HRTF), which is the core technology to generate three-dimensional (3D) virtual sound. Due to the errors in sound location by average HRTFs, it is necessary to produce 3D sound based on individualized HRTFs. In this paper, the morphological influence on HRTFs was studied to examine the possibility of HRTF individualization by morphological features of human body. From correlation analysis and principle component analysis (PCA), it was found that morphological measurements had different effects on the magnitudes of the HRTFs at different frequencies. Some key measurements were detected to well reflect the HRTF variations.
