The test process - SISI
The audiometer produces an intensity increment every 5 seconds. Each increment has a rise time of 50 milliseconds, a dur-
ation at full strength of 200 milliseconds, and a decay time of 50 milliseconds. The size of the increment can be varied
from 0 to 5 dB in 1 dB steps (selected on-screen from the Increment box), although the test is scored only on the per-
centage of 1 dB increments correctly identified by the patient. Twenty 1 dB increments are presented during the test. If
the subject responds 10 times out of the 20 1 dB increments, the sensitivity index is 50%.
Before starting the test
Before starting the test, present five 5 dB increments to give the patient a noticeably intense increment to respond to.
