## audiogram_disc6.jpg

The image is an audiogram, which is a graph used to show hearing sensitivity at different frequencies for each ear. The x-axis represents frequency in Hertz (Hz), ranging from 250 Hz to 8000 Hz. The y-axis represents the decibel level of sound intensity that can be heard by the person being tested.

There are two sets of data points on the graph, one represented by red triangles and the other by blue squares. These represent hearing sensitivity for different conditions:

- **Red Triangles (AC Unmasked):** This set shows how well a person hears in quiet conditions without any masking noise.
- **Blue Squares (BC Masked):** This set indicates how well the same person hears when there is background noise present.

Each point on the graph corresponds to a specific frequency and decibel level. For example, at 250 Hz, the red triangle shows that the hearing sensitivity for AC Unmasked is around -10 dB HL (Decibels Hearing Level), while the blue square indicates it's about +30 dB HL when BC Masked.

To the right of the graph, there is a legend explaining what each symbol and key means:
- **AC Unmasked:** A circle with an "X" inside.
- **AC Masked:** A circle without any marking.
- **BC Unmasked:** An arrow pointing to the left.
- **BC Masked:** An arrow pointing to the right.
- **No Response:** A square bracket [ ].
- **Sound-field:** The letter 'S'.

The audiogram also includes a key for interpreting the symbols used in the legend. This helps in understanding which symbol corresponds to each condition of hearing sensitivity.

There are no people or characters depicted in this image; it is purely graphical data representing auditory testing results.
