Start Level
The Start Level Threshold Seek Option button is used to select the initial stimulus level (dB
HL) for the reflex threshold testing when the threshold seek protocol is selected from the
reflex menu. When the button is selected, a dropdown list of options is presented.
Stop Level
The Stop Level Threshold Seek Option button is used to select the final stimulus level (dB
HL) for the reflex threshold testing when the threshold seek protocol is selected from the
reflex menu. When the button is selected, a dropdown list of options is presented.
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 and then increase until threshold
criteria is met.
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.
