1.1 STREAMLINED PROGRAMMING METHODS

Custom Sound includes three streamlined programming methods that

make programming simpler for the recipient and reduce programming

time without compromising outcomes (preliminary data collected at the

Cooperative Research Centre for Cochlear Implant and Hearing Aid Innovation

in Melbourne

and in the US Streamlined Programming Study). Cochlear

recommends using one of these methods at the initial activation for recipients

who are using implant types that allow monopolar stimulation (i.e. have

extracochlear electrodes). After the recipient has some listening experience,

you can easily reﬁne and modify MAPs based on the individual’s feedback. The

streamlined programming methods use behavioural responses (behavioural

method) or objective measures, (objective offset method or objective preset

method). The behavioural method is appropriate for adults and older children

who can easily make reliable behavioural responses to sound. The objective

methods may be more appropriate for young children and other individuals

who have difﬁculty responding reliably to sound.

During the initial activation, it is recommended that you select ACE

™

/ACE

(RE) as the default sound processing strategy when recipients have at least

12 or more active channels available. Two independent studies by Skinner et

2, 3

found that approximately two-thirds of adult recipients preferred and

performed better with ACE. Another 25% preferred SPEAK and only about 8%

preferred CIS. Plant et al

recommend when recipients have less than 12 active

channels, to start with CIS since there may not be a sufﬁcient number of active

channels available for good spectral processing.

Streamlined programming is not recommended for use with Nucleus 22

implant types or when using other implant types with a bipolar mode

of stimulation. This is because interpolation cannot be used with bipolar

stimulation modes, due to possible differences in stimulation requirements

along the array.
