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
TW/Ratio
•
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.
