This study compiles and analyzes experimental data on the mechanical properties of the human middle ear. The results show that there is larger uncertainty in the stiffness properties of the tympanic membrane, ligaments, and tendons compared to the ossicles' mass. Additionally, the uncertainties of the middle ear response vary across frequency, and vibration measures are more uncertain than input impedance and reflectance. These findings provide the basis for the development of probabilistic models of the human middle ear.
Many experimental data on the human middle ear (ME) mechanics and dynamics can be found in the literature. Nevertheless, discussions about the uncertainties of these data are scarce. The present study compiles experimental data on the mechanical properties of the human ME. The summary statistics of mean and standard deviation of the data were collected and the coefficients of variation were computed and pooled. Moreover, the linear correlation and distribution were assessed for the ossicles' mass. Results show that, generally, the uncertainties of the stiffness properties of the tympanic membrane, ligaments, and tendons are larger than the uncertainties of the ossicles' mass. In addition, the uncertainties of the ME response vary across frequency. The vibration measures, such as the stapes' velocity normalized by the sound pressure at the tympanic membrane, are more uncertain than ME input impedance and reflectance. It is expected that the results presented in this study will provide the basis for the development of probabilistic models of the human ME. (C) 2022 Acoustical Society of America.
