5.5. Reflex options
The CONFIGURATION options (Section 12.2) may be used to make the
following settings for the reflex test conditions. Refer also to Section 3.3.
Reflex selection
Use the ▲ and ▼ keys to choose the circumstances when a reflex
measurement is to be made (always, never, only if a compliance peak is
found, or only after confirmation is made at the start of the test sequence).
In cases where a compliance peak has not been established a pressure of
0daPa is used. Press the ► key to confirm the selection or the ◄ key to
cancel.
Reflex levels
Use the ▲ and ▼ keys to choose the maximum level of reflex stimulus to
apply and the step size between the levels of the preceding stimuli. The
maximum level of stimulus may be set between 85dBHL & 100dBHL. Press
the ► key to confirm the selection or the ◄ key to cancel.
Reflex frequencies Otowave 102-4 only
Use the ▲ and ▼ keys to choose between 1000Hz only or 500Hz, 1000Hz,
2000Hz & 4000Hz for the frequencies at which the reflex stimulus is to be
applied. Press the ► key to confirm the selection.
Reflex threshold
Use the keys to choose the change in compliance required to signify that a
reflex response has been detected (0.01ml to 0.5ml). The default is 0.03ml.
Reflex autostop
By default the reflex test at each frequency will stop at the lowest level of
stimulus that produces a response. By setting REFLEX AUTO-STOP to NO
the Otowave 102 will test for a reflex at all selected levels. (Note that
100dBHL at 4000Hz is not available).
Reflex filter
Use the keys to choose either 2Hz or 1.5Hz. The default of 2Hz is suitable
for most circumstances. However if a smoother reflex plot is required for
better interpretation 1.5Hz may be chosen.
5.6. Error messages
The following error messages may be seen during the test sequence.
