Description of intervention(s) / exposure
Treatment: Devices - CP1170 sound processor
Treatment: Devices - CP1150 Sound processor

Experimental: CP1170 sound processor - Take home use of CP1170 Sound processor for 2 weeks followed by in booth testing of the investigational device.

Active Comparator: CP1150 sound processor - In booth testing of CP1150 sound processor.


Treatment: Devices: CP1170 sound processor
The CP 1170 sound processor will be used to determine the hearing performance with the new implementation of ForwardFocus in SCAN 2 (SCAN 2 FF), as assessed by speech perception in noise.

Treatment: Devices: CP1150 Sound processor
Active comparator off the ear sound processor.
