The audiogram is a chart with "Frequency in Hertz (Hz)" along the top, with ranges from 125 to 8000. Along the left-hand side is "Hearing Threshold Level in decibels (dB)" with ranges from -10 to 120. "Slight" is marked between 10 and 20 dB, "Moderate" is marked between 40 and 50 dB, "Severe" is marked between 70 and 80 dB, and "Profound" is marked between 90 and 100 dB.

A legend of symbols is along the bottom of the chart with different symbols for the right and left ears, including for "Earphone (no mask)," "Earphone (mask)," "Bone (no mask,)," "Bone (mask)," "No Response," and "Sound Field."

Inside the chart cells, the symbols are marked along the top with lines between them for each ear, and two side by side purple waves indicate test results from the left to the right side.
