Mechanical damage of tympanic membrane in relation to impulse pressure waveform - A study in chinchillas.
TL;DR: The TM rupture threshold difference between the open and shielded cases suggests that an acoustic role of helmets may exist, intensifying ear injury during blast exposure and provides the biomechanical mechanisms for blast induced TM damage in relation to overpressure waveforms.

Experimental and Modeling Study of Human Tympanic Membrane Motion in the Presence of Middle Ear Liquid
TL;DR: The results from both experiments and FE model show that a simple deflection shape with one or two major displacement peak regions of the TM in normal ear was observed at low frequencies while complicated ring-like pattern of the deflection shapes appeared at higher frequencies.
Characterization of the Nonlinear Elastic Behavior of Chinchilla Tympanic Membrane Using Micro-fringe Projection
TL;DR: The mechanical properties of an intact, full tympanic membrane inside the bulla of a fresh chinchilla were measured and the relationship between the applied pressure and the resulting volume displacement was determined and analyzed using a finite element model implementing a hyperelastic 2(nd)-order Ogden model.

Dynamic properties of round window membrane in guinea pig otitis media model measured with electromagnetic stimulation.
TL;DR: It is suggested that middle ear infection primarily affects the stiffness of the RWM due to the morphological changes that occur in AOM ears, and the coil-magnet coupling method for assessment of RWM function may provide a valuable new approach to characterizing the mechanical response when reverse driving is selected for middle ear implantable devices.

Biomechanical Measurement and Modeling of Human Eardrum Injury in Relation to Blast Wave Direction.
TL;DR: Modeling results indicate that the sensitivity of TM stress change with respect to P1 pressure (dσ/dP1) may characterize mechanical damage of the TM in relation to blast waves.
