摘要：

Head-related transfer functions (HRTFs), which represent the sound transmission process from sound sources to human ears, are widely used in virtual sound reproduction and relevant fields. In order to utilize the multiple dimensionalities of HRTFs, an extraction and modeling method of median-plane spectral characteristics is proposed on the basis of independent component analysis (ICA). Moreover, a subjective discrimination experiment is carried out to validate the applicability of the proposed model. Calculation results show that the mean value of median-plane spectral distortion decreases gradually with the rise of expansion order, and a weighted combination of the preceding six-expansion components represents the main part of median-plane spectral characteristics. Furthermore, experimental results show that no auditory degradation is perceived when the proposed ICA-based median-plane spectral model is employed at the elevations from 45° to -45°. © 2018, Editorial Department, Journal of South China University of Technology.
