Abstract
The standard dummy head of Chinese adult male is designed by Communication Acoustic laboratory of Communication university of China. The head-related transfer functions of the dummy head installed with different pinna structures have been measured. There are 11 different types of pinna model plus a pinna-absent type, which is installed on the dummy head. The variation and difference of HRTF caused by detailed pinna changes is analyzed using similarity coefficient. It's the foundation for further investigation the impact on the sound perception of the physical structure of the pinna.
