dB Step
The dB Step Threshold Seek Option button is used to select the level (dB) step
size between the start and stop level for the reflex threshold testing when the
threshold seek protocol is selected from the reflex menu. When the button is
selected, it toggles between the options (1, 2, 5 dB).
Seek Below Start Level
When set to On, if a reflex is detected at the initial Start Level of Threshold Seek,
the intensity level will decrease until no reflex is detected.
Verification
The Verification Threshold Seek Option button is used to select if the threshold
is verified and what criteria is used for the verification for the reflex threshold
testing when the threshold seek protocol is selected from the reflex menu. When
the button is selected, it toggles between the options:
•
None – no verification is performed
•
Repeat – a repeat of the stimulus level where the threshold was found
•
Step above – a test at the next stimulus level above where the threshold
was found
Threshold Level
The Threshold Level Threshold Seek Option is used to set the admittance change
(in mmhos) that indicates a reflex threshold. The +/- buttons are used to
increase/decrease the level. When the reflex reaches the threshold, testing is
stopped and the level (dB HL) where the threshold was found (and verified if
verification is in use) is stored. A TS marking by the curve indicates that the
reflex threshold was collected using the threshold seek protocol.
Non-Threshold Seek
The Non-Threshold seek section is used to set the parameters when not using the
threshold seek function.
Start Level
The Start Level Non-Threshold Seek Option button is used to select the initial
stimulus level (dB HL) for manual reflex threshold testing. When the button is
selected, a dropdown list of options is presented.
dB Step
The dB Step Non-Threshold Seek Option button is used to select the level (dB)
step size when the stimulus level is increased or decreased for manual reflex
threshold testing. When the button is selected, it toggles between the options (1,
2, 5 dB).
Timing
Timing
The Timing button selects timing method used for the presentation of the
stimulus for the reflex testing. The button toggles between the Auto and Manual.
The Auto mode uses the on/off timing that has been specified in the PC Config
App and downloaded to the instrument. The Manual mode presents the stimulus
