8.3.2 Using STORE in the SISI test
Note
•
A maximum of four different sets of SISI values can be stored for both left and right ear.
Storing results
1. When the test is completed for a frequency, press
STORE
to store:
– SISI % score, number of dB increments administered,
– dB increment,
– dB level for test signal and masking signal (if applicable).
– An * symbol appears by the frequency and an x/o symbol for the left
or right side.
2. Test the next frequency.
8.4 ABLB (Alternate Binaural Loudness Balance)
In this test a tone is transmitted at the same frequency to the left and right ear alternately . The patient must decide when
the same volume is achieved in both ears. The patient indicates this by pressing the patient responder.
1. To select the test press
SPECIAL
once or more until ABLB is shown.
2. Press
ABLB
once, and the test display is shown.
The top line shows the intensity for Right and Left channel and the test
name.
The frequency of the test tone and the rate of alternation from ear to
ear and back again (the alternating frequency) appear in the bottom line.
Changing alternating frequency
To change the alternating frequency:
1. Press
SETUP
once and use the
Right level
knob (0.25 - 2.5 Hz).
2. Press SETUP again to implement the new setting.
3. You can present the signal in two ways:
– present the signal to the patient by pressing the INT button, or
– press the
REVERSE
button to present the signal continuously. You can then interrupt the test signal by pressing
the
INT
button.
Signal presentation (normal/ REVERSE ) follows the normal rules (see Stimulus/speech count buttons ► 24 ).
8.4.1 Using STORE in the ABLB (Fowler) test
Storing equal volume values
Press
STORE
to store values of "equal volume".
• You can store up to five sets of measurements for each test frequency.
If you try to save more than five sets of measurements for a given frequency, the message "No more STORE" is shown.
