Improved method to individualize head-related transfer function using anthropometric measurements

摘要

Humans have an inherent ability to encode the directional information of an incident sound in an acoustical transfer function The head, external ears, and torso of a listener can transform the spectral information of a sound as it travels from a sound source to the eardrum [1] The head-related transfer function (HRTF) is used to describe this physical transformation. However, the HRTF greatly* varies from person to person. Several studies have addressed the issue of HRTF individualization [2-7].. It has been suggested that marked perceptual distortion might occur when one listens to sounds spatialized with nonindividualized HRTFs Individualized HRTFs can increase the number of the cues necessary for spatial localization, particularly for elevation localization.
