CLINICAL GUIDANCE | SECTION ONE

1.1.1 Behavioural Procedures

1. Measure impedances by performing an implant test.

2. In the Open or Create MAP screen, create a new MAP by selecting the

required MAP parameters from the available drop-down menus and

clicking Create. Alternatively, you can select and open an existing MAP

that you can modify.

The default streamlined programming method is the behavioural one and

by default, channels 22, 16, 11, 6, and 1 are highlighted for measurement.

Any ﬂagged channels are noted.

3. Click on the Streamlined Programming drop-down menu. Using the

“Set Ts” buttons, measure the T-level on each of the default channels

(indicated by wider bars) using an ascending method. By default, the

starting level is 80 CL. For more information, see Programming

Principles T-level Assessment Procedure. Custom Sound

automatically interpolates T-levels on the unmeasured channels

(indicated by the thinner bars).

4. At initial activation, use of streamlined programming methods is

recommended. However, if a large variability in the proﬁle is observed,

additional measurements should be made in this area of the array, for

example on the basal electrodes (e.g. electrodes 4, 3 and 2) to improve

the accuracy of the interpolation and obtain optimum sound quality.

5. To set C-levels, click the “go live” button (the large green button) and

talk to the recipient as you gradually increase C-levels globally by

clicking the <up> arrow under “live Cs”. During live voice testing, the

microphone sensitivity is set to 12 by default for most processors (the

optimal sensitivity) and the volume control is set to maximum (this can

be reduced). Adjust C-levels so that ongoing conversational speech is

comfortably loud. It is recommended reading aloud to the recipient and

allowing the person to follow along with the text while tracking loudness

using the loudness-scaling chart. As the loudness level gets closer to

comfortably loud, reduce the step size from 5 CL to 2-3 CL. If necessary,

you can reduce the microphone sensitivity slightly.

6. Note: When going live to set C-levels, ADRO

is typically used, however it

can be turned off when setting C-levels using live voice if desired.

If you choose to use the traditional method of measuring individual C-levels

and then testing in live speech mode, it is recommended that you initially

reduce the microphone sensitivity or volume if it is at maximum because the

sound could be too loud. Gradually increase the sensitivity up to the default of

12 and check sound comfort at maximum volume.
