61 CLINICAL AUDIOMETER
In the next figure, High Frequency Audiogram, the x axis is labeled Right Ear or
Left Ear Frequency (kHz) and is marked at the frequency levels of 8 kHz, 10 kHz
12.5 kHz, 16 kHz, and 20 kHz. The dashed grid lines are displayed at the intermediate
frequencies of 9 kHz, 11.2 kHz, 14 kHz and 18 kHz. The y axis ordinate is incremented
every 10 dB, starting at -20 dB HL and ending at 110 dB HL. A crosshair, spanning
the length and width of the audiogram, shows the current frequency and dB level for
the ear under test.
