Influence of eardrum perforation position and eardrum perforation size on ear sound transfer function
 Straka, Martin ; Dušek, Daniel (referee) ; Pellant, Karel (advisor)
This thesis describes influence of eardrum perforation and perforation patching (myringoplastics) on sound transfer function. Perforation size, perforation position and inluence of graft material on hearing are discussed. This thesis is completed with 3D mathematical modeling in ANSYS system. The 3D finite element model of human ear is remodeled to represent the perforated and graft covered stage. Mathematical modeling is used for sound transfer calculations and for the discussions of the influence of tympanic membrane perforation on hearing. Set of audiological examination is processed and it is made the comparison between mathematical modeling results and audiology results.
