Weber; Stenger - Interacoustics AD528 Gebrauchsanweisung

Function keys
1 Press the '1,2,5 dB' button to toggle the dB step size. The current step size is indicated on the label of
this button.
2 Hold down the Meas. type button and use the wheel to select the threshold type – HL (hearing level),
MCL (most comfortable level), UCL (uncomfortable level).
3 Change the condition indication: None, Aided, Binaural, or Both. The function is only applicable during
free field testing.
4 The masking table shows the intensity of the masker for the stored threshold.
5 Man: Manual tone presentation each time the tone switch is pressed.
Rev: Continuous tone presentation which will be interrupted each time the tone switch is pressed.
6
Continuous: By default a continuous tone is presented.
Single: Presents the tone with a pre-set length.
Multi: Presents the tone pulsing continuously.
The length of the single and multi-tone is adjusted in tone settings.

Weber

The Weber test distinguishes between conductive and sensorineural hearing loss through use of a bone
conductor. Use the indications to show where the tone is perceived. If the patient hears the tone better in the
poorer ear, then the hearing loss is conductive, and if the tone is heard better in the better ear the hearing
loss is sensorineural at the given frequency.
The symbols for Weber correspond to the following soft buttons.

Stenger

The Stenger test is used when a patient is suspected of feigning a hearing loss and is based on the auditory
phenomenon 'The Stenger Principle', that states that only the louder of two similar tones presented to both
ears at the same time will be perceived. As a general rule it has been recommended to perform the Stenger
test in cases of unilateral hearing loss or significant asymmetry.
Press Tests and select Stenger to enter the Stenger test. The screen is the same as for pure tone
audiometry. Please refer to the tone audiometry test screen above for a description of the test screen. The
function keys 1, 5 and 6 are available from the Stenger test screen.
In the Stenger test the signal is presented to both ears when the tone switch is pressed. Use the wheel for
channel 1 to adjust the intensity of the primary ear and the wheel for channel 2 to adjust the intensity of the
secondary ear.
