Abstract

Human ear canals cannot be measured directly with existing general measurement tools. Furthermore, general non-contact optical methods can only conduct simple peripheral measurements of the auricle and cannot obtain the internal ear canal shape-related measurement data. Therefore, this study uses the non-invasive method, computed tomography (CT) technology, to measure thegeometric shape of the ear canal to complete the anthropometry of external auditorycanal. The results of the study show that the average height and width of ear canalopenings,and the depth of the first bend for maleare generally longer, wider and deeper than those forfemale. In addition, the difference between the height and width of the ear canal openingis about 40% (p<0.05). Hence, currently the circular cross-section shape of the earplugs should be replaced byan elliptical cross-section shape during manufacturing for better fitting.
