9 Testing with Zodiac Diagnostic or Clinical - Stand-Alone
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
If the system cannot automatically analyze a reflex measurement, a
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
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.
56
SC
(Static Peak Compliance) when volume equivalent units are used
(Tympanometric Width/Tympanometric Ratio). Describes the steepness of the curve.
No Response
