B. Tympanometry graph
The graph area shows the tympanometric curves and can rescale automatically to fit the curves.
• Tympanometric curves
• Pressure and admittance scales
• Ear canal volume bar
• Norm area
The ear canal volume is shown to the right of the graph.
C. Reflex Screening results
The detected reflex is shown in the results area.
• Stimulus type level
• Deflection curves
If a reflex is not detected, then the curve of the loudest stimulus is displayed together with a No Response indication.
D: Tympanometry results
The results table shows the results related to the currently selected curve:
• Probe (the probe tone in Hz)
•
TPP
(Tympanometric Peak Pressure)
• ECV (Equivalent Ear Canal Volume
•
SA
(Static Admittance), or
SC
(Static Compliance) when volume equivalent units are used
• TW/Ratio (Tympanometric Width/Tympanometric Ratio). Describes the steepness of the curve.
•
Type
(Jerger types A, As, Ad, B, C, D and E denote the shape of the 226 Hz curve). You can set the type to be
determined automatically, and you can subsequently change it manually, if necessary.
