Abstract
Principal component analysis (PCA) was used to reduce dimension and simplify the analysis of HRTF amplitude spectra of dummy head installed with different artificial pinna model. In addition to no-pinna case, 4 kinds of structural model of pinna were discussed. Directional mean of the corresponding frequency bands and the basic functions of spectral shape of HRTF were given to illustrate the effect of different pinna details act on HRTF. It proves, besides the no-pinna case, No.2 pinna structure (with connected cymba conchae and cavitas conchae), No.4 pinna structure(with thickened antitragus) affect the HRTF most obviously in the horizontal plane. However, the effect of helix alone on HRTF is rather little. As a whole, different pinna structural detail has different effect on HRTF amplitude spectrum.
