Note: Some tests are purchased as additional licences for the AC440. If a license has not been
purchased, the test will be greyed out in the start screen selection and it will not be shown in the ‘test
tree’ of the protocol settings (at number 1 in the above figure).
3) Select the default start Intensity (Tone, Speech, SISI, Weber). Use the dropdown lists to select the
preferred settings. Checking Switch extended range on automatically allows the user to go to high
intensities without the need for manual activation of the extended range. The extended range opens
automatically as soon as the cursor moves into that area of the audiogram
4) In the Automatic output selection the Ch 2 opposite Ch 1 output can be ticked. This way channel 2
will automatically choose the opposite output as channel 1 (e.g. if channel 1
is set to Right, channel 2 will automatically select Left). At Bone masking: the
user sets which transducer is chosen by default to mask bone
measurements. This option will not be active if Ch 2 opposite Ch 1 output is
not used.
5) Adjust the Pulse of the test signal. If Multi Pulse or Single Pulse are ticked
the pulsation length (in mS) can be adjusted using the sliders. Note the
option to add multi or single pulse in the front screen (as shown on the graph).
6) Direct Access Buttons: right click on the buttons to decide which direct access buttons appear on the
main AC440 screen. Up to 4 buttons can be displayed.
7) Set Talk forward to the desired intensity using the slider. To allow talk forward in free field tick the
corresponding check box. Tick Talk forward input calibration to adjust talk forward input level to 0 dB
VU. This is helpful if the talk forward microphone is always located at the same position.
8) If desired, allow Monitor on live voice speech. This function is rarely necessary as it is likely to cause
acoustical feedback. However, if the test is performed under circumstances where this is not the case,
monitoring of live voice can be allowed by ticking the check box.
9) sssssssUnder Settings – representation tick Show maximum intensities. This will allow for
showing/not showing the transducer maximum intensities in all tests. This is the dark shaded area on
the graph can in the tone audiogram be (de)activated by the dedicated button under Counselling
overlays
.
10) Use BSA logic forces the audiometry to use symbols according to the standards of the British Society
of Audiology (BSA).
11) Only show input/output on mouseover will hide the not selected input and output options while the
mouse is not over it and results thereby in a calmer screen.
