Rainville Test
The first three tests use air conduction as output, so set up the audiometer
and arrange the patient as previously described in 5.2.1 on page 23. For
Rainville, set up as described in 5.2.2 on pages 24 and 30.
All four tests are accessed from the Select Function Menu. Press Softkey 3 to
access the following menu: SOFTKEY 3
Select Special Test:
SISI Fowler Stenger Rainv.
Select test. Only the S.I.S.I requires further selection (Stimulus side) while
selecting any of the other tests accesses the test setup required
automatically and enables you to start testing immediately.
5.4.1 S.I.S.I. TEST
1. Select SISI and the following is displayed:
(Special, SISI, Air) Stimulus side ? :
Left Right
2. Select Left as ear to be tested first and the following screen appears:
Freq. SISI (A) L:Tone Score: 0( %)
1000 Hz 1-5dB 20 dB Pres.: 0 Stop
3. HL intensity is default set at 20 dB but should be set at 20 dB over the
patient's threshold for frequency to be tested (normally starting at 1000
Hz).
HL 20 dB Over
Threshold
4. Explain to the patient that he will hear a continuous tone and that the
intensity will be increased for a very short time (200 ms) once every fifth
second. Ask the patient to press the patient signal each time he hears a
change in the stimulus tone.
5. To demonstrate, set the Hearing Level at an intensity that can easily be
heard, ensure that the modulation increment is set at the default 5 dB
and press the
TONE SWITCH to initiate the test.
TONE
NOTE : The 5 dB modulation increment is for demonstration purposes only
as it should be easy for the patient to perceive the intensity changes -
neither presentation nor score counter is activated when 5 dB is selected.
The S.I.S.I. Test itself should always be conducted with 1 dB modulation!!
ATTENTION!
6. After the patient has been instructed and has practiced sufficiently, stop
the test by pressing Softkey 5.

7. Reset by pressing Softkey 1. SOFTKEY 1
