DESCRIPTION
DEFAULT
Level Mode:
Please note:
Depending on the
LEVEL MODE
selection, the
LEVELS
screen will contain different content.
ONE LEVEL:
Use the
S keys
to choose the level of reflex stimulus
to apply. Only one level will be tested in the measurement. The
maximum level of ipsilateral stimulus may be set to maximum
100dBHL; the maximum level of contralateral stimulus may be set to
110dBHL.
MULTILEVEL:
Use the
S 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 ipsilateral stimulus may be
set between 85dBHL and 100dBHL; the maximum level of
contralateral stimulus may be set between 85dBHL and 110dBHL.
Multilevel
Sequence:
Choose the type of reflex stimulus to apply: ipsilateral only, ipsilateral
followed by contralateral or contralateral only.
Ipsi
Levels:
Choose ipsilateral or contralateral and press the
►
key to confirm the
selection.
Then 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 ipsilateral stimulus may be
set between 85dBHL and 100dBHL; the maximum level of
contralateral stimulus may be set between 85dBHL and 110dBHL.

5 dB steps
Frequencies:
Use the
▼
key to scroll through the frequencies available for each of
the ipsilateral and contralateral stimuli (500Hz, 1000Hz, 2000Hz &
4000Hz), and then the
▲
key to select (
) or deselect (-) the
frequencies at which the reflex stimulus is to be applied. Then press
►
to save the entire selection.
1kHz ipsi
Selection:
Choose the circumstances when a reflex measurement is to be made
(always, never, only if an admittance peak is found, or only after
confirmation is made at the start of the test sequence).
In cases where an admittance peak has not been established a
pressure of 0daPa is used.
Only if peak
found
Threshold:
Choose the change in admittance required to signify that a reflex
response has been detected (0.01ml to 0.5ml).
0.03 ml
Auto-Stop:
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 will test for a reflex
at all selected levels.
Yes
Filter:
Choose either 2Hz or 1.5Hz.
2Hz is suitable for most circumstances.
2 Hz
