The complexity of the human ear grants it a pivotal role in both receiving and transmitting acoustic stimuli. This study investigates the impact of middle ear damping and stiffness on the acoustic properties of the outer ear. Using finite element modeling, we simulated the behavior of the outer ear while taking into account the mechanical characteristics of the middle ear. To achieve this, we constructed a three-dimensional geometric model of the outer ear from radiographic images, while the middle and inner ears were modeled using the equivalent mechanical impedance of a mass-spring-damper system. Our findings highlight the significant influence of middle ear damping and stiffness on sound waves in the ear canal and resonance frequency, thus directly affecting auditory perception. These findings deepen our comprehension of the underlying mechanisms governing the transmission of sound stimuli through various ear components, emphasizing the critical importance of damping and stiffness in auditory perception.
