SISI
The SISI (Short Increment Sensitivity Index) test requires the generation of a
continuous tone that increases in intensity a selected amount at a selected point in
time. The SISI has intensity increments of 5 dB, 2 dB and 1 dB. An intensity
increment is added to a tone in the selected channel for 200 msec, every 5
seconds.
The top section of the display has the common elements found on all the
previously described screens. The center section displays the results of the
testing. Using the Correct/Incorrect score buttons, obtain a percentage correct of
the patient responses. The results are added to the table when the test is Stored.
The Navigation Menu has an option for the dB Step (continuous HL level) and an
option for the SISI step (intensity increment). The results are not transferred to
GSI Suite via the data transfer and therefore should be entered as a comment.
