Program Hybrid mode
Note
The Nucleus 8 Sound Processor or Nucleus 7 Sound Processor can only be
programmed in Hybrid mode with Custom Sound software Version 7.0 or above. For
more information, see the Custom Sound software user guide or online help .
About setting frequency boundaries
An overlapping MAP
A minimally overlapping MAP is automatically generated by the Custom Sound software.
The low frequency information is presented via acoustic stimulation only. High frequency
information is presented via modified frequency-to-electrode allocation tables. The
boundaries of where acoustic stimulation stops and electrical stimulation begin are
determined by the recipient's residual hearing.
About Hybrid mode prescription options
Overview of Hybrid mode prescription choices
The Custom Sound software provides three prescriptive methods for programming the
Hybrid receiver. The fitting formulas are based on adult recipients and are provided to give
you a starting point for making fine tuning adjustments to the frequency-gain
characteristics of the system's acoustic output. There is no one fitting method that is
universally accepted. It is possible to use preferred prescription targets to manually match
the acoustic gain and power output.
The options for Hybrid mode are:
• CHP: Cochlear Hybrid Prescription. By default, CHP with WDRC (Wide Dynamic Range
Compression) is selected. It can be used with or without compression in Hybrid mode.
• NAL-RP: National Acoustic Laboratory. Revision for profound losses prescriptions that
equalise prescribed gain to make each frequency band of speech of equal loudness to
maximize speech intelligibility.
• DSL: Desired Sensation Level Prescriptions. Aims to preserve loudness among speech
frequencies.
