Performing a measurement
Figure 47
The screen (Figure 47) shows the buttons for
Ipsi
and
Contra
as well as the different frequency buttons. They are
always presented according to the default settings in the
setting menu and from low to high frequencies. It is possible
to select or deselect one of the frequencies by pressing on it.
Pressing the
Ipsi
or
Contra
button will turn on/off all
frequencies or set the selection back to default settings.
NOTE:
If there are no frequencies chosen in the default
settings it is not possible to turn on an
Acoustic Reflex
test by pressing the
Ipsi
or
Contra
button. To turn on a
Reflex, press the individual frequency to be tested.
The
Ipsi
and
Contra
button also show the level range (for
automatic level adjustment) or the level (for fixed levels).
See section 5.6.10.
The measurement starts when the probe is properly placed in the ear (when in the
Basic
Settings
menu the automatic start of the measurement is selected (see section 5.6.3) or
the
Play
button is pressed (when the manual start of the measurement is selected).
When performing Acoustic Reflex testing it is possible to interrupt the measurement
for pausing by pressing the
Pause
button, the
Probe
button (both only possible in
manual mode) or removing the probe from the ear (no seal state). While having the
probe removed from the ear the display will show a message box asking if you want to
stop the measurement. Press
Stop
to stop the measurement. Continue the
measurement by inserting the probe into the ear again.
The evaluation of the
Acoustic Reflex
test results depends on the configuration
displayed as a graph or table.
Figure 48
Graph:
The measured curves are displayed simultaneously
to the ongoing test. For easier evaluation the pass criterion
threshold and the zero line are shown in the graph.
Underneath each diagram the frequency and the intensity
level in dB
NOTE:
The deflection of the graph can be modified in the
settings. See section 5.6.9.
Figure 49
Table:
The measured intensity level in dB HL is displayed
simultaneously to the ongoing test. Underneath each diagram
the frequency is displayed (Figure 49).
