 This paper presents a stochastic finite element model of the human middle ear, which takes into account individual variations in the model parameters. The authors found that these variations can lead to significant changes in the output of the model, particularly at higher frequencies. This suggests that deterministic models may not accurately represent the true behavior of the middle ear and could lead to misdiagnoses or incorrect device development.
