IMPEDANCE MEASURING SYSTEM
Probe tone:
Frequency:
226 Hz, 1000 Hz
Level:
85 dB SPL at 226 Hz, 69 dB SPL at
1000 Hz with AGC, assuring constant
level at different ear canal volumes.
Air pressure:
Control:
Automatic.
Indicator:
Measured value is displayed on the
graphical display.
Pressure change rate:
Speed at compliance peak (change in
settings):
Automatic (Dynamic from 60 daPa/s for
low gradient and 200 daPa/s for a
gradient larger than 5 daPa)
Minimum 950 daPa/s): slow, very
precise results
Medium (250 daPa/s): compromise of
speed and precision
Maximum (>400 daPa/s): fast,
screening
Range:
-400 daPa to +200 daPa.
Pressure limitation:
-750 daPa and +550 daPa.
Compliance:
Range:
0.1 ml to 8.0 ml at 226 Hz probe tone (Ear
volume: 0.1 ml to 8.0 ml) and 0.1 mmho to
15 mmho at 1000 Hz probe tone.
Test types:
Tympanometry
Automatic.
Indicators:
Graphical display
Compliance is indicated as ml for 226 Hz
and as mmho for 1000 Hz and pressure
as daPa.
Stimulus level is indicated as dB HL.
Memory:
Tympanometry:
1 curve per ear, per Tympanometry test.
And theoretically an infinite number of tests
per protocol.
