CLINICAL GUIDANCE | SECTION ONE

where T-NRT fell in relation to the behavioural dynamic range. As a

result of the large variability between recipients, offsets may need to be

changed depending on the stimulation rate being used for the MAP. The

current C-level offsets in Custom Sound may result in MAPs that are too

soft for some recipients when using the higher stimulation rates.

8. The current clinical recommendation is to combine the preset method

with any behavioural measures wherever possible, in order to determine

an offset for each individual. To change the preset defaults, go to Clinician

Preferences and the Progressive MAPs tab. To have an offset applied in

the negative direction, it is necessary to enter the value as a positive

number. To have the offset applied in the positive direction, enter the

value as a negative number. Then, create MAPs with progressively larger

dynamic ranges. Alternatively, drop the T/C-level proﬁle to a minimum

value and increase the levels using live speech mode until a behavioural

response is observed. Initially, T-levels can be brought up to this point and

MAPs with progressively wider dynamic ranges made. Where behavioural

responses are not available to determine an offset for any individual, it is

recommended that clinicians proceed conservatively.

9. Sweep the C-levels to look for any sound awareness or behavioral

responses before going live with the ﬁrst MAP. Go live with the MAP and

watch for any responses to sound. Note: this is a very conservative MAP.

Sweep C-levels of each progressive MAP prior to going live.

10. Save the MAPs.

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

them to the sound processor.
