Acoustical dummy head for Chinese adults
Na Qi, Meng Zihou · The Journal of the Acoustical Society of America · 2012
An acoustical dummy head is designed based on the Chinese national code of adult head geometry. From a survey of more than four hundreds Chinese adult auricle structure, a typical physiological structure of auricle is selected for the acoustic dummy head. Eyes, nose and other head structure are simplified. The HRTF of the acoustical dummy head is measured. The cues relating to sound source localization, including interaural time difference (ITD),interaural level difference (ILD), and spectral features introduced by pinna, nose, hair and other detail structure of head, are analyzed. And then the analytical data is compared with a full-scale dummy head. The result shows that the acoustical dummy head retains the main acoustic characteristics attributed to auditory localization. A listening test is carried out to verify this property.
