CLINICAL GUIDANCE | SECTION ONE

When programming a Nucleus

24 implant and the SPrint processor with 20

active channels, the default is Table 8 (188 - 7938 Hz) and the available non-

defaults are Table 1-7. Changing to Table 6 reduces the input range to 188 -

6063 Hz. For the ESPrit 3G the default input frequency range reduces as the

number of channels is reduced. However, other table numbers are available to

further modify the input frequency range. For example, for a 20-channel MAP,

the default is Table 7 (120 - 8658 Hz). Changing to Table 5 provides an input

frequency range of 100 - 7215 Hz. When converting between sound processors,

it may be necessary to change the table number for the CP810/Freedom

processor to match that used in the SPrint or ESPrit 3G, i.e. where the default

table was not used. The table number is changed via the Parameters screen of

Custom Sound. The options for changing the table number are listed in the pull-

down menu. For example, when converting a 22-channel SPrint MAP that uses

Table 4 (188 - 6938 Hz), use CP810/Freedom Table 22-B. When converting from

an ESPrit 3G to the CP810/Freedom processor, it may not be possible to achieve

the same input frequency range. In this case, choose the Table that provides the

closest input frequency range to the ESPrit 3G.

User adjustable frequency boundaries

Custom Sound allows you to manually adjust the channel frequency

boundaries for the CP810 and Freedom processors to have more ﬂexibility

when customizing recipient MAPS (e.g. MAPs for speciality devices), or to try

different frequency boundaries for different channels or groups of channels

to troubleshoot hearing problems. Typically, the user adjustable frequency

boundaries are used for the following applications: clinical research, Hybrid

™

partial insertions, Auditory Brainstem Implants (ABI), Double Array implants

and MAP conversions.
