Figure 3.

(A) Effect of a sensor in the vestibule on H_V in individual ears: rH_V = ${\mathbf{H}}_{\mathbf{V}}^{\mathbf{V}}$/H_V. Data for ch18 and ch19 are shown by dashed and dot-dashed lines, respectively; others by thin solid lines. Mean effects ±1 s.d. shown by thick solid lines and shading. (B) Ratio of normalized stapes velocity with various other inner-ear manipulations to ${\mathbf{H}}_{\mathbf{V}}^{\mathbf{V}}$ with a sensor in the vestibule: the vestibule hole open but no sensor in place (VO), a sensor in the vestibule hole and a hole in scala tympani (STO), and sensors in both the vestibule and ST holes (SST). The gray regions are ±1 s.d. of |${\mathbf{H}}_{\mathbf{V}}^{\mathbf{V}}$| about 1 and of $\mathrm{\angle }{\mathbf{H}}_{\mathbf{V}}^{\mathbf{V}}$ about 0. The result that the plotted ratios are generally within ±1 s.d. of ${\mathbf{H}}_{\mathbf{V}}^{\mathbf{V}}$ suggests that the other manipulations had little additional effect on ${\mathbf{H}}_{\mathbf{V}}^{\mathbf{V}}$.
