Eclipse Additional Information
The suggest waveform markers are only intended as guidelines and the function cannot determine if the selected peak
stems from a patient response or is just noise.
Always use this function with care and ensure that each of plotted waveform markers are correct.
7. Report: By selecting the Report button in the upper menu bar, you can write a report for the session. If
report templates are entered in the System Setup then you may choose one of these. You may edit such a
report template for this session if needed without changing the original contents of the report template.
8. Print: This function will provide a printout according to the printout designed in the Print Wizard for the
selected Test Protocol.
9. Display A/B curves: By pressing the A/B button the two curves A and B which average makes up the
main curve, will be shown.
They can be used for evaluating wave reproducibility, as they are actually recorded as independent curves.
With alternating polarity stimulation, the A curve will hold all the condensation sweeps, and the B curve will
hold all the rarefaction sweeps.
Furthermore displaying A&B curves will help pinpointing of the cochlear microphonic (going opposite direc-
tions) and to differentiate between these and Wave I.
10. Display contra curve: By pressing this button the contralateral ear waveform response will be shown.
This has certain diagnostic values:

Wave I can sometimes be difficult to pin point in the normal ipsilateral curve. By comparing the ipsi-
lateral curve to the contralateral curve, Wave I should be present only on the ipsilateral curve.

Wave IV and Wave V are often separated in the contralateral curve, which will help the identification
of Wave IV and Wave V.

When doing bone conduction testing both cochlea are prone to the same stimulation. The ipsilateral
curve and the contralateral curve will show the early responses (e.g. Wave I) for each ear individu-
ally. Please note however, that later waves (e.g. wave V) will be seen on both ipsi and contra curves
regardless of which ear receives the stimulus.

Wave I will therefore in this way indicate the integrity of the two cochleas as seen at the contralateral
curve and ipsilateral curve respectively. If wave I is present in only the ipsilateral curve, it is likely that
the contralateral curve was evoked by the ipsilateral cochlea. Separate testing of the other ear, with
masking, is likely to be necessary to assess the poorer hearing ear.
11. Talk Forward: Activates the talk forward function. The test will pause while this function is activated.
12. Single curve will display only the highlighted curve on the screen with larger display gain for easy visual
evaluation. Browsing is done with the tab key or by clicking on the hidden curve's handle with the mouse.
A completed curve is evident when the handle/box becomes filled in with color.
In Single Curve Mode you may also have an automatic display of the latency templates for the selected
curve. The single curve option may be selected as a default parameter for each individual protocol and may
also be selected/deselected by the Single Curve. This feature is selected in the Auto Protocol Setup, or in
the Temporary Protocol Setup.
