6.1.5 Stenger
The Stenger test is a test to confirm the presence of pseudohypacusis. During
this test, two tones of the same frequency will be presented simultaneously to
both ears, and only the louder tone will be perceived. Select HL to perform the
Stenger test and select both ears (9). Instruct the patient to press the response
button when the tone is heard. Present a tone to the better hearing ear 10 dB
above threshold and wait for the patient to indicate the tone has been heard.
Now present the tone to the poorer ear 10 dB below the indicated threshold
(the patient may “ignore” this tone). Present the tones simultaneously by
pressing the lock function button (14) and the STIM Mode button (8) to set it
to interrupter mode. If the patient responds it is a negative. If the patient does
not respond it is a positive Stenger, indicating that the tone is heard in the
poorer ear and the patient is ignoring the stimulus.
