A. On-line values
The on-line values show the current settings and status.
• Probe tone in Hz
• Pump speed
• Sweep direction
• Current equivalent volume/admittance (678, 800, 1000 Hz probe tone)
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. The ear canal volume is shown to the right of the graph.
• Norm area
C. Reflex Screening results
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.
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 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.
