The image is a graph that displays data related to hearing thresholds measured in decibels (dB) over different frequencies in kilohertz (kHz). The x-axis represents frequency, ranging from 125 kHz to 8000 kHz. The y-axis represents the hearing threshold level in dB HL.

There are four sets of data points on this graph:

- **Right Air:** Represented by circles.
- **Left Air:** Represented by crosses.
- **Right Bone:** Represented by open squares.
- **Left Bone:** Represented by filled-in squares.

Each set of data points shows the hearing threshold level for different frequencies. The lines connecting these points are not explicitly drawn, but they would typically be used to show trends or patterns in the data if present.

The graph includes a legend on the right side that identifies which symbol corresponds to each type of measurement (right air, left air, right bone, and left bone). 

There is no text or diagram within the graph itself other than the axis labels and the legend. The numbers along the x-axis are 125, 250, 500, 750, 1000, 1500, 2000, 3000, 4000, 6000, and 8000 kHz. The numbers along the y-axis are in increments of 10 dB HL from 0 to 100.

The graph appears to be a scientific or medical chart used for analyzing hearing data, possibly comparing air conduction (sound passing through the air) versus bone conduction (sound passing through the skull).
