Abstrakt: Any dysfunction of vestibular system leads to various diseases, the most common among them is Benign Paroxysmal Positional Vertigo (BPPV). BPPV is most found in elderly people causing vertigo/dizziness which leads to fall and serious injuries. The primary system in inner ear helping in human body balancing and postural adjustment is the cupula. Cupulolithiasis is a type of BPPV caused when otoconia get settles on the cupula. In the present work, a three-dimensional model of cupula and otoconia particle is modelled. A free vibration modal analysis is carried out on the cupula with and without otoconia particle to extract the natural frequency and mode shapes. Change in natural frequency of the cupula due to presence of otoconia particle is presented. Present work has a future scope involving fluid solid interaction (FSI) and extracting response of the cupula incorporating damping to obtain complete dynamic characteristics of cupula. The extracted results help in future investigation of new therapeutical solution to treat BPPV. [ABSTRACT FROM AUTHOR]
