(Color online) Cochlear measurements when the ear was driven with a pure tone of frequency 9998 Hz. (A) Sketch of the cochlear region under observation. (B) B-scan, with round window membrane, BM, OCC, and Reissner's membrane surfaces in view. Location of A-scan of vibration measurement is indicated in the red vertical line. The red solid line to the left shows the magnitude of the A-scan, positioned to show the correspondence with structures in the B-scan. (C) A-scan with BM and OCC regions indicated. The regions corresponding to points 1 and 2 (BM region) and points 3 and 4 (OCC regions) are explored in (D) and (E). (D) Thick red curves: reported response amplitudes at points 1 and 2 and in-between and adjacent points. Other curves: theoretical reported displacements when accounting for phase leakage. The calculation used the A-scan and vibration results from the prominent points 1 and 2. Several ΔΘ_AB0 values were used to illustrate the sensitivity of the phase leakage prediction to this value. The thick-dashed green curves show theoretical reported displacement found using a slightly different optical sectioning curve.
