Note: Rev (Reverse) and if preferred Multi Pulse should be selected for channel 1 and Rev
(Reverse) or Sim (Simultaneous) for channel 2.
4) Clarify the test procedure to the patient. Explain that he/she will now hear speech and the assignment
is to repeat the presented words or numbers.
5) Use channel 2 for presenting speech to the better ear and set the intensity level to 20 dB above the
threshold.
6) Use channel 1 for the poorer ear and set the intensity level 20 dB below the level of the good ear.
7) Present the speech material to both ears simultaneously. Keep the intensity level of the better ear
fixed and increase the intensity for the worse ear in 5 dB steps. If the hearing loss in the worse ear is
genuine the patient will keep repeating correctly to the speech signal presented to the better ear
(Negative Stenger). If the patient is feigning the hearing impairment he will stop repeating correctly
when the level of the worse ear exceeds the signal presented to the good ear (Positive Stenger).
8) Use the arrow buttons on the PC keyboard or the dedicated keyboard to set the frequency and
intensity. You also choose Mouse operated audiometry
and perform the test using only the
mouse. Left click to stimulate and right click to store the threshold.
