CLINICAL GUIDANCE | SECTION ONE

4. The default streamlined programming channels 22, 16, 11, 6, and 1 are

highlighted. In the Method box, click the “Select NRT/Objective Levels”

button. Select the measurement type (e.g. NRT), the values you wish

to use from the “date of measurement” and click ok (more than one

set of measurements may be selected.). This brings the T-NRT values

(blue markers) on the measured channels into the Set Levels screen.

Alternatively, in the Set Levels screen you may click and drag the blue

T-NRT markers up to the T-NRT values.

5. Select “NRT/Objective Offset” in the Programming Method box. Custom

Sound highlights Channel 11 and interpolates the remaining T-levels

to keep the difference between T-NRT on each measured channel and

the starting T-level equal to the difference between T-NRT and starting

T-level difference on Channel 11. This has the effect of maintaining

the T-NRT proﬁle. Measure the T-level on Channel 11. Custom Sound

automatically adjusts the overall T-level proﬁle based on the measured

T-level on Channel 11. To measure additional T-levels, double click on the

speciﬁc channel.

6. To set C-levels, click the go live button and talk to the recipient as you

gradually increase C-levels globally by clicking the <up> arrow next

under “live Cs”. During live voice testing, the microphone sensitivity is

set to default of 12 (the optimal sensitivity). Watch the recipient for any

behavioural responses or indications that the sound may be too loud. It is

recommended that you initially set C-levels conservatively.

7. Stop the stimulation and sweep all of the channels at 80% and then at

C-level to conﬁrm that sounds are comfortably loud. For adults or older

children who can complete the task, you can balance loudness across the

channels by sweeping a small set of channels (4 – 5 at a time) to conﬁrm

equal loudness. To adjust individual channel C-levels that have not

been measured, double-click the speciﬁc channel or click the

“make all channels measurable button” and then modify individual

C-levels as necessary.

8. Save the MAP.

9. You may select to create progressive MAPs from the original MAP.

10. Personalize the MAPs for the listening environment(s) prior to writing

them to the sound processor.
