(5) Repeat the test by reducing the signal level in 10dB steps until the
patient no longer responds. Then increase the signal level in 5dB
steps until a response occurs and note this level.
(6) Repeat step 5 until the patient responds three out of a maximum of
five times at the same signal level. This indicates the patient’s hearing
threshold level for that frequency. Either mark the threshold on an
audiogram card or press the appropriate ear key once to activate the
Threshold Retention Function and save the threshold level on screen.
(7) Proceed to the next test frequency. It is common practice to test the
frequencies in the following order: 1k, 2k, 3k, 4k, 6k, 8k and 500 Hz.
(8) Repeat steps 2 to 7 for the other ear.
