In 2016, the Nucleus® Hybrid™ Hearing1 Acoustic Kit2 was approved for all Nucleus implants. As you may have experienced, converting the Nucleus 6 (CP910 or CP920) or Nucleus 7 (CP1000) sound processor to use an acoustic component, and fitting Hybrid Hearing MAPs in Custom Sound, is quick and easy. Support documents can be found under the Resources section of myCochlear Clinic.
The four program locations in either the Nucleus 6 or the Nucleus 7 sound processor make it easy to allow your patient to evaluate, if needed
- A Hybrid mode MAP and an electric-only (non-Hybrid mode) MAP
- Hybrid mode MAPs that differ in their acoustic and electric frequency boundaries
- Hybrid mode MAPs that differ in gain for the acoustic component
- Any combination of the above
There are, however, three parameters that must match across all MAPs you wish to write to the sound processor:
- Receiver Type
- Mould Type
- Vent Size
- Receiver Type
For Nucleus 7 only, you must specify the Receiver Type: 60, 85 or 100. Custom Sound will recommend the Receiver Type based on the audiogram entered for the patient.
In the Set Levels screen, the Acoustics screen may be accessed.
In this screen, the receiver type may be changed and a new MAP created.
In the Write to Processor screen, however, if two Hybrid Mode MAPs with different Receiver Types are selected to be written to the processor, the following message will appear:
- Mould Type
For both Nucleus 6 and Nucleus 7, Hybrid Mode MAPs that have different Mould Types cannot be written to the same processor.
In the Write to Processor screen, if two Hybrid Mode MAPs with different Mould Types are selected to be written to the processor, the following message will appear:
In this case, you may find it helpful to use the MAP Compare function in Custom Sound, which will show you how the MAPs differ at a glance:
- Finally, for both Nucleus 6 and Nucleus 7, Hybrid MAPs that have different Vent Sizes cannot be written to the same processor. The message shown in item 2 above will appear if two Hybrid Mode MAPs with different Vent Sizes are selected to be written to the sound processor.
Please contact your Clinical Territory Manager with any questions about fitting Hybrid Hearing.

The Acoustic Component should only be used when behavioral audiometric thresholds can be obtained and the recipient can provide feedback regarding sound quality. The Hybrid L24 Implant is approved in the U.S. for adults ages 18 and older.
