Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Investigational device - Sound Processor

Experimental: Investigational device - Sound Processor -


Treatment: Devices: Investigational device - Sound Processor
At visit 1 the subjects will complete self-reported assessments with respect to "pre-study experience" using precursor Sound Processor (comparator). At visit 1 the subjects will then receive the Investigational device (Sound Processor) which should be used during the following 6 weeks. At visit 3 the subjects will complete self-reported assessments regarding Investigational device and participate in audiology tests regarding both Sound Processors, comparator and Investigational device. The subject shall decide their preferred choice made by selection between Investigational device and the comparator.
