The image is a scientific diagram from the book "Audiology: Science to Practice" by Kramer & Brown. It consists of two graphs labeled A and B, which illustrate tuning curves in auditory physiology.

**Graph A (Normal Tuning Curve):**
- The x-axis represents frequency in kilohertz (kHz), ranging from 0.1 kHz to 100 kHz.
- The y-axis represents Sound Pressure Level (SPL) in decibels (dB SPL).
- There are two labeled points on the tuning curve: CF=1 kHz and CF=10 kHz, indicating characteristic frequencies of 1 kHz and 10 kHz respectively. These represent the most sensitive frequency for a given ear.
- The tuning curve shows a peak at these characteristic frequencies with a high-frequency slope and low-frequency slope. The peak is labeled as "Tip" on the graph.

**Graph B (Shape of Bekésy's Tuning Curve):**
- This graph also has an x-axis representing frequency in kHz, ranging from 0.1 kHz to 100 kHz.
- The y-axis represents SPL in dB SPL.
- The tuning curve is shown with a broader peak compared to the normal tuning curve, indicating a wider range of frequencies that can be detected at similar sound levels.

The text below each graph provides additional context:
- Graph A describes a "Normal tuning curve illustrated for 1 kHz characteristic frequency (CF) and 10 kHz CF." It explains how sensitive an ear is most to its characteristic frequency.
- Graph B illustrates the shape of Bekésy's tuning curve, which shows damage to active processes in the cochlea. The broader peak indicates that fewer frequencies can be detected at similar sound levels.

The diagrams are accompanied by labels and arrows pointing to specific features on each graph for clarity.
