Creating an Acoustic Reflex Protocol
Above is the Acoustic Reflex protocol editing window.
Protocol Name: the text entered into the Protocol Name field is what will appear in the instrument when
the protocol is loaded. This should be kept to approximately 14-16 characters in length so that the full
protocol name can be viewed on the instrument display.
Evaluation Criteria: check the box if a Pass or Refer outcome should be determined for this protocol.
Indicate the number of passing frequencies required for the overall test result to be
Pass.
Number of
passing frequency bands for a test pass can be set to any value between 1 and 4, but cannot exceed the
total number of frequency bands tested.
Using the check boxes under the
Reflex Stimulus
column, select up to 4 stimuli to be presented.
Using the check boxes 60-95 dBHL, select up to 6 intensities to be presented
Green check marks and/or red anti symbols will be shown in the area corresponding to each stimulus-
intensity combination. The green check mark indicates an allowed combination, whereas the red anti
symbol indicates a conflict between the stimulus type and the intensity.
The compliance change criterion determines the amount of compliance change required to consider the
acoustic reflex present. This is selectable between 0.03 ml and 0.09 ml.
Note: when using the 1kHz probe tone, broadband noise is the only allowable stimulus type. Use the
check box to the left of the broadband noise stimulus row to select this option.
