The detected reflex is shown in the results area.
•
Stimulus type level
•
Progress indicator during measurements
•
Deflection curves are shown when a reflex has been detected.
If a reflex is not detected, the highest stimulus is displayed together with a
No Response
indication.
If the system cannot automatically analyze a reflex measurement, a
Not Tested
indication is shown.
C. Reflex Screening 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 Peak Admittance), or
SC
(Static Peak 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.
