Quantitative Reappraisal of the Helmholtz-Guyton Resonance Theory of Frequency Tuning in the Cochlea

Figure 7

Maximal basilar membrane displacement at resonant frequency for sounds of 0, 60, and 120 dB in air as a function of distance from the stapes, computed using expression (9). The vertical scale is logarithmic. Dashed line indicates nonlinear behavior associated with membrane stretching as well as membrane bending at extreme incident sound pressure levels.
