Brief summary

The experimental sound processor and associated accessories is a sound processor that aims to combine the sound processing, connectivity, comfort and discretion of the behind-the-ear Nucleus 7 sound processor, This study requires usability listing tests in both the clinic and at-home use of the prototype design.

Interventions

All participants will be fitted with an investigational sound processor (CP1150) for use with 1 or 2 ears by a qualified audiologist. It will take approximately 30 minutes to fit a sound processor (connect to the existing cochlear implant). The study will run over 3 phases for a total of 9 months. In phase 1, only one ear will be fitted. If the subject has 2 implants, the second will not be used. In phases 2 and 3, if the subject has two compatible implants, then both will be used. Phase 1 i

All participants will be fitted with an investigational sound processor (CP1150) for use with 1 or 2 ears by a qualified audiologist. It will take approximately 30 minutes to fit a sound processor (connect to the existing cochlear implant). The study will run over 3 phases for a total of 9 months. In phase 1, only one ear will be fitted. If the subject has 2 implants, the second will not be used. In phases 2 and 3, if the subject has two compatible implants, then both will be used. Phase 1 is usability and speech testing conducted on a single day. Phase 2 includes a 2-4 week take-home period reviewing the usability of the CP1150. Phase 3 includes a 2-4 week take-home period reviewing the usability of the device and speech testing. There may be up to 4 months between phases; during this time you will not be using the CP1150 sound processor. Device use will be monitored through questionnaires, diaries, data logs from the sound processor and usability testing scenarios to be completed during periods of at-home use. A total of 5 clinical visits will be required over the 3 phases. Each clinic visit will take approximately 3 hours. Usability testing is reviewing a list of activities to determine if the subject can complete them. Speech testing is completed in a sound booth. All the procedures are conducted by an investigator who is a trained audiologist.
