The image is a graph titled "An example of an audiogram used to record pure-tone thresholds." It includes a grid with horizontal lines representing decibels (dB HL) ranging from -10 to 120, and vertical lines representing frequency in Hertz (Hz), ranging from 250 Hz to 8000 Hz. The graph is divided into two main sections: the left side shows the audiogram itself, while the right side provides an audiogram key.

The audiogram grid has a scale on both axes. On the horizontal axis, there are intervals of 100 Hz from 250 to 8000 Hz. The vertical axis represents decibels in increments of 10 dB HL, starting at -10 and increasing up to 120.

The audiogram key on the right side explains what each symbol means:
- A circle with a line through it (O) indicates "AC unmasked" for the right ear.
- A triangle pointing upwards (Δ) signifies "AC masked" for the right ear.
- A square with a line through it (□) represents "BC unmasked" for the right ear.
- A square bracket ([ ]) denotes "BC masked" for the right ear.
- Two arrows pointing downwards (↓↓) indicate "No response."
- An arrow pointing to the left and then downward (←↓) signifies "Sound-field."

The audiogram key also includes a column labeled "Left Ear," which is currently blank, indicating that there are no recorded responses or measurements for the left ear in this example.
