•
The ordinate scale represents the stimulation power in dB HL,
•
The x scale represents the frequency in Hz,
•
The graphical background represents the normal hearing threshold for this patient according to age and gender.

The green area indicates "better than normal" hearing,
2.
The yellow area indicates normal hearing,
3.
The red area represents a hearing loss compared to normal hearing thresholds.
