Figure 6.

Amplitude of pure piezoelectric resonance. (A) Amplitude is plotted against frequency with (dashed lines) and without (solid lines) mechanotransducer in the hair bundle. The $\gamma$ values are, respectively, 0 (left), 0.5 (middle), and 1 (right). (B) Enlarged plot with (solid lines) and without (dashed lines) strain-induced polarization stiffness (the second term in $B_h$). The $\gamma$ values are, respectively, 0 (right), 0.5 (middle), and 1 (left) for the dashed plots. A small amplitude increase and downward frequency shift with an increase in $\gamma$. The frequency scale is normalized to the resonance frequency ${\omega }_r$.
