Validation procedures. A) Stapes velocity transfer functions (HStap = VStap/PEAC; mean across three repetitions in specimen 359L) were measured before (○) and after (△) intracochlear pressure sensor insertion to verify comparable magnitudes (note that the angle of the LDV with respect to the stapes motion differed between measurements, thus absolute magnitudes could vary somewhat). Gray band represents the 95% confidence interval (CI) from (Rosowski et al., 2007). B) Round window velocity (blue) was compared to Stapes velocity (red) at 400 Hz to verify a 180° phase difference. The stimulus was a 1s duration tone pip. C) Cochleostomies were created near the base of the stapes and the round window (RW) to enter into the scala vestibuli (SV) and scala tympani (ST) respectively. D) After all experimental conditions were completed, intracochlear pressure probe placement was verified by dissecting away the bone between the two cochleostomies, and verifying that the basilar membrane (BM) was between the two fenestrations.
