PINNA: Acceptance and Performance of CP1110 Sound Processor With Experienced Adult Cochlear Implant Recipients.
Study Details
Study Description
Brief Summary
The clinical study aims to investigate acceptance, actual-use usability and speech performance with a new behind-the-ear sound processor (model number: CP1110) system, compared with the commercially available Nucleus 7 Sound Processor (model: CP1000) system, with particular focus on the acceptance of and satisfaction with a noise reduction feature in the Automatic Scene Classifier 'SCAN'.

Detailed Description
The clinical study aims to investigate acceptance, actual-use usability and speech performance with a new behind-the-ear sound processor (model number: CP1110) system, compared with the commercially available Nucleus 7 Sound Processor (model: CP1000) system, with particular focus on the acceptance of and satisfaction with a noise reduction feature in the Automatic Scene Classifier 'SCAN'. This study will build on the evidence collected in previous Nucleus 7 Sound Processor take home studies and will also aim to confirm the in-booth performance of CP1110 and Nucleus 7 Sound Processors.

Outcome Measures
Primary Outcome Measures
- Speech Reception Thresholds (SRT) assessed in spatially separated speech and noise (S0Nrearhalf). [6 months]
Paired difference in dB SRT (AuSTIN) between the CP1110 Sound Processor with ForwardFocus ON (SCAN) and ForwardFocus OFF (SCAN) (65 dB SPL S0Nrearhalf 4TB).
Secondary Outcome Measures
- Speech Reception Thresholds (SRT) assessed in spatially separated speech and noise (S0N3). [6 months]
Paired difference in dB SRT (AuSTIN) between the CP1110 Sound Processor with ForwardFocus On (SCAN) and ForwardFocus OFF (SCAN) (65 dB SPL S0N3 Babble).
- Adult cochlear implant speech perception in quiet with the CP1110 Sound Processor and the Nucleus 7 Sound Processor. [6 months]
Paired difference in percentage CNC Words correct in quiet (50 dB) with the CP1110 Sound Processor and Nucleus 7 Sound Processor.
- Adult cochlear implant subjective hearing performance and sound quality with the CP1110 Sound Processor and Nucleus 7 Sound Processor. [6 months]
Paired difference in Global Speech, Spatial and Qualities of Hearing Scale SSQ12 scores after experience with the CP1110 Sound Processor and Nucleus 7 Sound Responses on the SSQ12 have a minimum value of 0 and a maximum of 10, wherein a higher score means a better outcome.
- To evaluate acceptance and satisfaction of the CP1110 Sound Processor. [6 months]
Responses on the 'CP1110 Questionnaire 1' after at least 2 weeks of experience with the CP1110 Sound Processor and 'CP1110 Questionnaire 2' up to 6 months later.
