## tuning_curvesb.jpg

The image is a graph that illustrates sound pressure level (in dB SPL) on the y-axis against frequency in kHz on the x-axis. The graph has two lines: one solid and one dashed.

- **Solid Line**: This line represents "Shape of Bekésy's tuning curve" which indicates the passive process.
  
- **Dashed Line**: This line shows "With loss of active process of OHCs," indicating a scenario where the active process is not functioning, likely due to the outer hair cells (OHCs) being inactive.

The y-axis ranges from 0 dB SPL up to 100 dB SPL. The x-axis spans from 0.1 kHz on the left side to 100 kHz on the right side.

There are no people or characters in this image, and there is text that explains what each line represents.
