(a) Amplitude of umbo displacement versus frequency of the acoustic stimuli at 120 dB SPL (aditus open versus aditus closed) in the ear canal. The finite element model predicted umbo displacements were close to McElveen's experimental results. (b) Amplitude of predicted stapes footplate displacement versus frequency of the acoustic stimuli at 120 dB SPL (aditus open versus aditus closed).
