Biomechanics of the tympanic membrane

摘要: The tympanic membrane is a key component of the human auditory apparatus which complex biomechanical system, devoted to sound reception and perception. Over past 30 years, various bioengineering approaches have been applied ear modeling particularly middle part. membrane, included in ear, transfers waves into mechanical vibration from canal ear. Changes structure properties due diseases or damages can deteriorate transmission. An accurate model simulates acoustic-mechanical transmission, could improve clinical surgical intervention. In this paper detailed survey biomechanics focusing on finite element method conduced. Eight selected models are evaluated compared deducing main features most design parameters published models, mainly geometric, constraint material aspects. Non-specified replaced with commonly employed values. Our simulation results (in terms modal frequencies umbo displacement), numerical experimental results, show good agreement even if some scattering appears indicate need further investigation validation.
