Consultation of the measure
The tabular presentation allows you to immediately see the frequencies for which the patient's hearing threshold is
too high. You can click in the boxes to restart a measure in manual mode with the preset parameters (ear, frequency,
power).
The graph contains several pieces of information:
•
The blue curve with crosses represents the air conduction measure on the left ear.
•
The red curve with circles represents the air conduction measure on the right ear.
•
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 .
1.
The green area indicates "more" than normal hearing,
2.
The yellow area indicates normal hearing,
3.
The red area represents a hearing loss compared to normal hearing thresholds.

•
The red curves with circles represent the air conduction measures taken on the right ear,
•
The blue curves with crosses represent the air conduction measures on the left ear,
•
The blue dotted lines with brackets represent the bone conduction measures taken on the left ear,
•
The red dotted lines with square brackets represent the bone conduction measures taken on the right ear,
•
The white dotted lines with red and blue brackets represent the Weber test.
