On the oscillation behavior of the incus-stapes joint (author's transl).
A two-channel inductive measuring system in the human temporal bone preparation was used to oscillographically record oscillations of incus and stapes as well as to observe the phases between the two auditory ossicles at the same time. In the frequenzies between 300 and 1,200 Hz it was not possible to prove clearly a phase difference, in the higher frequency ranges (approximately from 2,000 Hz upwards), however, a phase difference was observed to occur regularly to an extent of 90 degrees and more.
