Fig. 8. Relative ossicular response at the distal tip on the malleus head in line with the stimulation direction of the same five right ears for lateral (black) and vertical (gray) stimulation. Each frequency response was shifted along the logarithmic frequency scale to bring the resonant frequencies into alignment at an arbitrary frequency of 150 Hz. Over the frequency band tested, malleus velocity amplitudes in response to lateral stimulation exceeded those in response to vertical stimulation.
